Picture pavement preservation as the unsung hero of road maintenance. It’s an approach that believes in proactively maintaining roads to prevent them from nosediving into a state where major rehabilitation becomes essential. As the age-old adage goes, prevention is invariably cheaper – and indeed smarter – than the cure.

So, buckle up, folks. This article will delve into diverse pavement preservation treatments and their power to extend the lifespan of our roads.

What’s Pavement Preservation and Why Learn About It?

Pavement preservation is more than a buzzword; it’s a proactive strategy championing the protection and upkeep of our existing roads. With a bouquet of ever-evolving techniques, it’s gaining traction as a wallet-friendly alternative to traditional construction and rehabilitation.

As an elegant shield against damaging oxidation, it preserves both aesthetics and structure – brightening your driveway and echoing your values and personality. Thinking about keeping your asphalt dazzlingly fresh? Let pavement preservation do the heavy lifting.

Different Pavement Preservation Treatments

Navigating the labyrinth of pavement preservation treatments can be complex. Each boasts unique prowess, but these treatments’ application isn’t one-size-fits-all. The key lies in a scrupulous examination of the specific situation and damage level before charting the optimal course of action.

Sealing and Filling Cracks

Cracks – those pavement nemeses – can’t be ignored. Acting as a blockade against water, sealing and filling cracks mitigate further damage and obstruct debris, negating the need for milling.

Take heed, though. These treatments don’t cater to grave structural issues, and an overzealous application could compromise visual appeal and skid resistance. Extreme caution with temperature parameters and moisture should ensure superior crack sealing.

Overlaying

Overlays are layers of either warm or hot mix asphalt added atop the milled pavement. Dubbed “thinlays” and “thicklays,” these ingeniously rectify minor issues like rutting and weathering and even restore skid resistance.

However, their utility wanes when faced with major structural damage, which may need a thicker overlay or even a complete overhaul. Thus, a solid understanding of the asphalt’s current state is integral to optimizing your overlay application.

Slurry Sealing

This treatment comprises water, asphalt emulsion, crushed rock, and additives applied to existing asphalt surfaces. Unlike fog seals, slurry seals boast aggregates, creating the ‘slurry’ that restores pavement flexibility, seals cracks, returns a black tinge to faded roads and protects the pavement structure.

Ideal for roads with minor to moderate distress, the frequency of its application, intermittent or cyclical, hinges upon location, climate, traffic load and pavement conditions. Indeed, it is one underdog giving road surfaces a fighting chance.

Micro-surfacing

Here’s micro-surfacing, slurry sealing’s savvy cousin. Like slurry, it blends asphalt emulsion, water, and tiny crushed rocks. Its secret weapon? Chemical additives that help it harden swiftly without relying on evaporation – a boon for shaded or high-traffic roads where slurry surfacing falters.

Sealcoating

Acting as a protective layer, this pavement treatment protects your asphalt driveway against damaging elements, including oxidation and fuel spillages.

Sealcoating is also more than just a defender. It adds a pristine, polished aesthetic, a lifesaver for property managers seeking to captivate tenants and customers with their stunningly maintained parking areas.

Chip Sealing

Chip sealing is a two-step technique that spreads asphalt emulsion – paving asphalt, water, polymer, and rejuvenator – onto existing pavement topped with crushed rock.

As a driveable surface, a component of a ‘cape seal,’ or an interlayer between asphalt surfaces, chip sealing efficiently seals narrow cracks, binds cracked pavement and protects the underlying structure from aging and traffic loads.

Final Thoughts

Ultimately, it boils down to one thing: The best way to start with prolonged asphalt longevity lies in vigilant inspection for cracks, potholes, water and oil damage.

Doing so lets you know what to do next – whether remedying the problem yourself or calling a professional. Remember, proactive care is the best solution for pavement preservation.

Whether you have a commercial parking lot or a residential driveway, taking care of your asphalt surface is essential to avoid costly pothole repairs. Taking the time and effort now to prevent them from forming is much easier and less expensive than fixing them later. Once a divot forms and the asphalt structure crumbles and breaks, it can become a real hazard causing harm to pedestrian traffic and costly vehicle repairs.

So, give yourself, your customers, employees and vehicle traffic a break by following the steps necessary for prevention. Here’s how:

1. Keep asphalt clean

We say this a lot but it’s worth repeating. The build up of rocks, debris, fallen branches, fuel and oil stains on an asphalt surface can cause damage. We recommend sweeping or blowing the asphalt surface clear of debris as needed or once a month in the summer. Also clean up any weeds, grass and plants that may be growing or thriving along the edges of your driveway or parking lot to prevent erosion of the gravel base. In the winter, keep your asphalt surface clear of ice and snow so that when a freeze/ thaw cycle occurs, it doesn’t seep into any surface cracks or form pooling areas of water.

2. Crack Fill

Living in Alberta, asphalt cracks are unavoidable. It’s common to find hairline cracks and there’s not a lot we can do about those. If you see a crack over a ¼ inch, sweep it clean and call a professional to have it filled. That little crack provides opportunity for water to erode the gravel base and weaken the asphalt structure. If it is left over the winter where a freeze/ thaw is bound to occur, the crack usually worsens and can lead to a pothole.

3. Seal Coat

Sealcoating provides a protective barrier that guards that asphalt from environmental factors such as UV rays, oil leaks and water. Additionally, it fills in smaller cracks that may not be immediately visible. With regular seal coating maintenance, you can reduce the damage that could lead to pothole formation in the future. Remember that seal coating is only a preventative measure, not a repair solution.

4. Add a temporary patch if needed

If there’s a pothole forming on your asphalt surface, cold-mix asphalt can be used as a temporary solution to mediate any hazards the pothole has created and give some protection to asphalt’s base layer. It is best to call an asphalt professional that can provide a proper, longer term fix with hot-mix asphalt.

Final Thoughts

Taking the time to inspect and maintain your asphalt regularly is essential for preventing potholes. From regular cleaning and maintenance to seal coating and patching, there are a few steps you can take to save yourself time and money in the long run.

Don’t wait until it’s too late–start taking preventative action now.

If you have just had your driveway repaved or are planning to do so soon, you may wonder when driving or parking on the freshly paved surface will be safe. Driving or parking on the asphalt driveway before it has fully cured can cause damage to the surface, so it’s important to know when it is safe to do so.

In this article, we will discuss the different factors that affect the curing time of an asphalt driveway and provide some tips to help you determine when it is safe to use.

Factors that Affect Curing Time

Several factors affect the curing time of an asphalt driveway. The most significant of these factors include:

Temperature: Hot temperatures generally cause asphalt to cure more quickly, while cooler temperatures will slow the curing process. For example, if the temperature is around 80 degrees Fahrenheit, the asphalt will take about 24 hours to cure, while in cooler temperatures, it may take up to 48 hours.
Thickness: Thicker layers of asphalt will take longer to cure than thinner layers. If your driveway has multiple layers of asphalt, it may take longer to cure.
Traffic: Heavy traffic on the driveway can cause damage to the asphalt before it has fully cured. It’s critical to avoid driving or parking on the driveway until the process is complete.

When is it Safe to Drive or Park on Freshly Paved Asphalt Driveway?

Typically, you should wait at least 24 hours before driving on a freshly paved asphalt driveway. However, the curing time can vary depending on the factors mentioned above.

It’s important to note that driving or parking heavy vehicles like campers or trailers on the driveway before it has fully cured can cause damage to the surface. The vehicle’s weight can cause the asphalt to sink and become uneven, leading to unsightly cracks and bumps. Additionally, if the asphalt is still curing, animals and pets should remain off the driveway to protect their paws from the heat of a freshly paved road, driveway or surface.

Tips for Maintaining a Freshly Paved Asphalt Driveway

After repaving your driveway, take proper care of it to ensure it lasts as long as possible. Here are some tips to help you maintain your newly paved driveway.

Avoid heavy traffic

As mentioned earlier, heavy traffic on a freshly paved driveway can cause damage to the surface. Avoid driving or parking on the driveway until it has fully cured.

Keep it clean

Regularly sweeping or hosing down the driveway can help prevent dirt and debris from building up on the surface. This can help extend the life of the driveway and prevent damage.

Sealcoat

Sealcoating your driveway can help protect it from the elements and prevent cracks and other damage. Sealing your driveway every 3 – 5 years is recommended to keep it in good condition.

Spring maintenance

Spring is a great time to perform maintenance on your asphalt driveway after the harsh winter months. Here are some steps you can take to maintain your driveway in the spring:

Remove debris: Remove any accumulated debris on the driveway’s surface, such as leaves, twigs, or branches, to prevent them from causing damage.
Patch cracks: Inspect the driveway’s surface for any cracks or potholes. Fill them in with an asphalt patching material to prevent further damage.
Clean stains: Remove any oil or other stains using a degreaser or other cleaning product. This will prevent them from causing permanent damage to the surface.
Keep clean edges: Keep weeds from encroaching on the edges of the asphalt surface and avoid planting trees nearby. The roots can cause damage to the surface layer and erode the aggregate base.

Taking these steps can help extend the life of your asphalt driveway and prevent damage, saving you money in the long run. By following these tips, you can ensure that your newly paved driveway remains in good condition for years. Check out more spring maintenance tips here.

Driving or parking on a freshly paved asphalt driveway before it has fully cured can cause damage to the surface. It’s important to wait at least 24 hours and perform a simple test to determine if it is safe.

As the snow melts away, it’s a good idea to perform routine maintenance to help keep your asphalt looking and functioning at its best. This article will explore some maintenance steps you can take now to ensure your asphalt stays in top shape.

Maintenance Tips

Keep your driveway, parking lot, or patio area looking amazing with these helpful maintenance tips.

Perform a Thorough Inspection

Once winter is done, it’s important to assess the condition of your asphalt. Start with a thorough visual inspection and note any cracks or potholes that may have formed over the winter months.

This is a good first step as it can help you identify what course of action to take moving forward.

Fill in Cracks and Potholes

Small cracks in asphalt can easily become larger when exposed to natural elements like snow and rain. To prevent this from happening, you should fill these small cracks with an appropriate material as soon as possible. Any potholes should also be filled to prevent further damage.

Practice Periodic Seal Coating

Practice periodic seal coating to help keep your pavements in top condition and prevent cracks from occurring.

Seal coating involves applying a protective layer of material to your asphalt surface. This can help protect against environmental factors such as UV rays, oil spills, and other contaminants that could cause your asphalt to deteriorate over time.

Clean and Remove Debris

It’s also important to keep your asphalt free of debris. This can be done by regularly sweeping away any dirt, leaves, or other debris built up over the winter months. Removing this debris will help keep the surface clean and in great condition.

Touch Up Your Striping

Striping is an important part of asphalt maintenance, as it helps to provide guidance and delineate parking spaces. Over time, the lines may fade due to natural wear and tear or weather conditions.

To keep your striping looking fresh, you should go over them with touch-up paint now and then. This will ensure your pavements look neat and professional.

Check Your Drainage System

While not directly related, your drainage system can have an indirect impact on the condition of your asphalt.

Inspect the gutters and downspouts around your property to ensure they are not blocked or damaged. This can help prevent water from pooling or draining onto your asphalt surface, which could cause it to degrade over time.

Importance of Spring Maintenance

The main benefit of performing spring maintenance on your pavements is to help prevent serious damage from occurring. While small cracks may seem like minor issues initially, leaving them unattended can lead to expensive repairs down the road.

Regular asphalt maintenance will help maintain its aesthetic appeal and prevent any safety issues due to uneven surfaces or potholes. The latter is especially detrimental since you can be held liable for injuries on your property due to negligence in upkeep.

Invest in Professional Maintenance

Some repairs are best left to the experts. Going DIY may seem tempting at first, but if you don’t have the right materials and experience, it can lead to more problems down the road. If the condition of your asphalt is more than you feel comfortable handling yourself, it’s a good idea to invest in professional maintenance services.

Holloway Paving can come and assess the condition of your asphalt, repair any damaged areas, seal coat surfaces, and give general advice on how best to maintain it moving forward.

Your driveway is many things – a place to park your car, part of your home’s curb appeal, and one of the first things people see when they come to visit. Over time, even the most well-maintained driveways can start to show signs of wear and tear. And eventually, you’ll have to replace your asphalt driveway.

In this article, we’ll explore five signs that you’re in need of an asphalt driveway replacement. From potholes to drainage issues and fading colour, we’ll help you identify the signs that could be affecting the safety and appearance of your driveway. Let’s get started!

Cracks

One of the most common indications that your asphalt driveway needs to be replaced is noticeable cracks. Small cracks may not seem like a big deal at first, but they can slowly grow over time and become a more serious issue. Having cracks means that water can seep into the underlying layers of your driveway, which can cause further damage and lead to more expensive repairs down the line.

If you notice cracks in your driveway, it’s best to have them repaired as soon as possible. However, if there are too many cracks or they’re overly large, it may be time to consider replacing your driveway altogether.

Potholes

Another similar sign is the presence of potholes. Potholes can form when water seeps into the underlying layers (thanks to cracks!) of your driveway and freezes, causing the asphalt to expand and contract. This can result in the asphalt breaking apart, leaving behind a hole.

Potholes can be dangerous for your car and your family, and they’re certainly not aesthetically pleasing. Just like cracks, potholes need to be addressed right away.

Drainage Issues

If water is not draining properly from your driveway, it can lead to standing water, which can ruin the texture and appearance of your driveway and create safety hazards. Poor drainage can be caused by a variety of factors, including a sloping driveway, clogged gutters, or a damaged drainage system.

Fading Colour

Asphalt driveways are typically black or dark gray in colour. As the years go on, the colour of your driveway may start to fade or become lighter. This might be from exposure to the sun, weather, and other environmental factors.

While fading colour may not seem like a serious issue, it might be telling you that your asphalt is getting weaker. A sealant could be an effective solution in this case, but if your driveway doesn’t cooperate with it, it’s time for asphalt replacement.

Age

While asphalt driveways can last for many years with proper maintenance, they will eventually reach the end of their lifespan. If your driveway is more than 10 – 20 years old and is losing its smoothness and shine, contact the professionals. A new driveway will not only improve the appearance of your home, but it will also provide you with a safer and more functional place to park your car.

Are you looking to upgrade the curb appeal of your home or business? Pathway paving provides a great opportunity to add a touch of sophistication that will draw the eye for years to come. There are two popular materials used in pathway paving: concrete and asphalt. Each material has its own benefits and drawbacks, making it essential for homeowners and businesses to be informed about their options before deciding which material is most suited to their needs. To help you make the right decision, we’ll take an in-depth look at both concrete and asphalt pathways. Let’s get started.

Concrete Pathways

Concrete paving is a cost-effective option when compared to the expense of interlocking tiles or pavement and can be a great addition to any outdoor space.

One of the primary advantages of using concrete pathways is their durability. They are also easy to clean and maintain with just a basic broom or pressure washer.

On the other hand, a major disadvantage is that concrete can be slippery when wet, making it an occasional hazard for pedestrians. In addition, concrete pathways that aren’t properly installed and maintained can crack due to soil movement or changes in temperature.

Because of concrete’s permanence, it’s difficult to make adjustments down the road if you decide you want a different style or design for your pathway. There’s no denying that concrete paving also takes more time to install than asphalt.

Here’s a quick breakdown of the pros and cons of concrete paving.

Pros of Concrete Paving:

Durability – Concrete paving is extremely durable and can last for many years without needing to be replaced.
Low Maintenance – Unlike asphalt paving which needs to be resealed periodically, concrete does not require as much maintenance.
Versatility – Concrete is versatile enough to be used in a variety of applications, such as driveways, patios, walkways, and more.

Cons of Concrete Paving:

Installation Time – Installing concrete can take much longer than other materials due to the need for drying time between each layer of material being applied.
Cracking – Although concrete is durable, it can still crack due to shifting soil or other environmental factors.
Costly Repairs – Over time, concrete can lead to unsightly cracks and require replacement in order to keep the area looking nice.

For added beauty, safety, and convenience, concrete pathways are an excellent choice for any outdoor space.

Asphalt Pathways

The strength, durability, and classic look of asphalt pathways make them one of the most popular choices. Aside from their attractiveness, asphalt pathways can also be cost-effective, low maintenance, and easy to install.

Especially in Canadian weather, asphalt is usually seen as the safest option for walkways due to its dark colour. This allows snow and ice to melt more quickly compared to lighter surfaces like concrete. Additionally, it provides a smoother experience for walking, biking, or skating.

However, asphalt paving may be more expensive because of its maintenance needs, and it doesn’t have the same longevity as concrete. For example, seal coating should be done every three years to keep the asphalt in good condition—more often than if you were using concrete.

Here’s a quick breakdown of the pros and cons of concrete paving.

Pros of Asphalt Paving:

Easy to install – Asphalt pathways are easy to install and can be completed quickly, allowing for a fast turnaround time from start to finish.

Aesthetic appeal – The natural black colour of asphalt makes a striking impression.

Cons of Asphalt Paving:

Maintenance – Asphalt pathways require regular maintenance, such as sealing, patching, and resurfacing, to maintain their appearance and prevent deterioration.
Shorter Lifespan – Compared to concrete, asphalt typically only lasts up to 25 years (less if not properly maintained).

By applying sealant and performing regular maintenance, you can extend your asphalt paving’s lifespan significantly. However, asphalt requires continual upkeep in order to remain effective.

Are you tired of the bumps and potholes that form on your gravel driveway? Looking for a way to make it easier to drive up and down your driveway with less maintenance required? Look no further because upgrading your gravel driveway to asphalt is the right solution.

While gravel driveways present a more natural appearance and are a more affordable option, they also have a number of drawbacks that should be taken into account.

In this article, we’ll look at the four top reasons asphalt driveways offer superior performance and better value, and explain why it might be time to make the switch.

Gravel Needs to Be Frequently Replenished

Gravel driveways are a popular option for many people because they are relatively low-cost and easy to install. However, they also require regular maintenance in order to look good and remain safe.

One of the key aspects of maintaining a gravel driveway is constantly replenishing it with new material. Gravel can be easily displaced by traffic or weather conditions such as rain or snow. This displacement causes ruts, cracks, and other irregularities that can become dangerous if left unchecked.

Gravel is also constantly replenished to prevent weeds from taking hold which can make the driveway appear unkempt. In no way is this maintenance convenient.

On the other hand, asphalt is a firm, solid material that can last for up to 20 years with proper maintenance before it needs to be replaced.

Gravel is Not Ideal For Snow Removal

Gravel and snow don’t get along very well. Gravel driveways are not ideal for snow removal because of the way the stones shift when exposed to extreme temperatures, making it difficult to plow or shovel a gravel driveway.

The shifting stones can also cause a bumpy surface which is hard and uncomfortable to walk on in winter conditions.

As gravel absorbs moisture from snow and ice, it becomes heavy and compacted, so any kind of snow removal equipment will struggle to remove it efficiently. Frozen or wet gravel can create an uneven surface that makes driving hazardous if you don’t have a four-wheel drive.

In comparison, an asphalt surface is much more resilient to snowplows scraping it than gravel. It can be easily cleaned and treated with salt when necessary, as it is designed to tolerate freezing temperatures and subsequent thawing.

Gravel Lacks Aesthetic Appeal

While gravel can come in many aesthetically pleasing colours and textures, even the most premium gravel has an unfinished and unprofessional appearance.

Gravel driveways often aren’t visually appealing because they are made up of small, loose stones that can easily be scattered by the wind or driven over, leaving an uneven and unsightly surface. The size and colour of the gravel used in a driveway may be inconsistent, resulting in a patchy look.

In contrast, asphalt driveways provide a consistently clean appearance due to their smoothness and resistance to wear.

Gravel Is Noisy

The high noise level produced by gravel driveways is a distinct disadvantage that is often overlooked. This noise is created by car tires rolling over the small stones which make up the surface of the driveway.

The sound can become especially loud when vehicles with low-profile tires travel on them. This is especially true when there is heavy rain, which causes puddles to form on the rocks and creates splashing noises when vehicles pass over them.

In order to reduce noise levels on a gravel driveway, homeowners can consider installing either smaller or smoother stones. Adding a thin layer of sand over the top of the surface will also help keep rocks in place and lessen sound due to shifting gravel particles.

However, for those seeking a home driveway that simply functions as intended without requiring a lot of maintenance, these measures may quickly start to feel like a burden.

Asphalt pavement is a vital part of our transportation infrastructure, providing a smooth and safe surface for vehicles to travel on. Its affordability and durability make it the material of choice for many roadway and parking lot projects.

The structure of asphalt pavement is designed to support the weight of traffic and withstand the forces of nature, while also providing drainage and flexibility to minimize cracking and potholes. Knowing how the layers of its structure work together makes proper design and construction possible to ensure a long-lasting asphalt pavement.

In this article, we’ll take a look at the different layers that make up asphalt pavement to better understand their characteristics.

Composition of Asphalt Pavement

Asphalt pavement is generally made up of four main layers, namely subgrade, subbase, base, and surfacing course. Each layer has different materials and properties that contribute to the overall strength and flexibility of asphalt pavement.

Subgrade

Typically composed of native soil or stabilized material, the subgrade provides a foundation for the pavement structure. It must be compacted and free of soft spots to provide a stable base for the other layers.

While some soils contain clay materials that are classified as unstable, they can be stabilized by mixing with lime, cement, or similar additives before compaction. Recycled materials like crushed concrete, reclaimed asphalt pavement (RAP), or a combination, can also be used in the subgrade layer.

When you have a solid subgrade layer, it will resist deformation from the weight of traffic and minimize cracking in the pavement, which reduces construction costs.

Subbase

Added on top of the subgrade, the subbase layer provides additional support and stability to the pavement. Common materials used are granular fill, crushed rock, lean concrete, and manufactured aggregate.

The particles in the subbase material are usually larger than those in the subgrade to allow better drainage. It also prevents smaller particles from being pushed up into the asphalt pavement during compaction.

While it’s not always necessary to have a subbase, a well-designed one will increase the overall lifespan of your asphalt pavement by distributing traffic loads and minimizing settlements. It can also be used as a stand-alone pavement in certain applications.

Base

The base layer is the main support for the asphalt pavement and can be made up of unstabilized or stabilized aggregates. Its thickness ranges from 4 to 6 inches, depending on the soil bearing capacity and traffic loads.

The base material is spread and compacted to achieve a high density for strength and durability. It must be able to resist the shearing force of traffic while also providing drainage to prevent water from saturating the base and subgrade layers.

Surface

As the topmost layer of the asphalt pavement, the surface must be able to withstand the wear and tear of traffic. It is usually made up of a hot mix asphalt (HMA) mixture, which is a combination of asphalt binder, filler, and aggregate.

The surface layer is generally divided into two sub-layers, namely the binder course and the wearing course. The binder course serves to bind the various materials together to provide structure to the HMA, while the wearing course ensures a smooth and wear-resistant surface for traffic.

A good surface layer can resist the effects of weather and aging, minimize tire noise, provide skid resistance, and improve drainage to provide a long-lasting driving surface.

Know what asphalt pavement looks like

Asphalt pavement is a complex structure made up of different layers, each with its own materials and properties that contribute to the strength and flexibility of the overall structure. A well-designed and constructed asphalt pavement will have a solid subgrade layer to provide a stable foundation, a subbase layer for additional support, and a base layer made up of high-density aggregates. The surface layer should be smooth and wear-resistant, with good skid resistance and drainage.

Every single year, millions of tons of asphalt pavement are removed from roads and parking lots across the country.

In fact, asphalt is one of the most recycled materials in the world. Asphalt is a very durable material, and with proper maintenance, asphalt pavement can last for decades. But even well-maintained asphalt will eventually need to be removed and replaced. When that happens, asphalt recycling is a great way to reduce waste and save money.

But what is asphalt recycling and how does it work?

What is asphalt pavement?

Asphalt pavement is a mixture of two key ingredients: asphalt binder or bitumen and crushed aggregate (stone, sand, or gravel). The asphalt binder is a sticky black substance that helps glue and bind the aggregate together.

The finished product we see on roads and parking lots is typically about 90 to 95 percent aggregate and 5 to 10 percent asphalt binder.

What is asphalt recycling?

Asphalt recycling is the process of taking old asphalt and crushing it down into smaller pieces. The crushed material can then be used as a base for new asphalt pavement. It’s a closed-loop system: old asphalt is removed, crushed, and used to make new pavement.

According to the National Asphalt Pavement Association, more than 87 million tons of asphalt were recycled into new mixes in 2020. Using recycled asphalt pavement (RAP) saves $3.3 billion every year and reduces the need for mining new materials.

How is asphalt recycled?

There are many methods for recycling asphalt, such as hot-in-place or cold-in-place recycling (CIPR) and full-depth recycling (FDR). But generally, asphalt recycling involves these steps:

The top layer of old asphalt is removed with a milling machine in a process called asphalt milling.
Pieces of crushed old asphalt, called chunks or millings, are mixed with some water and additives in an asphalt recycler.
For hot recycling, the recycler heats and combines the mixture to create recycled asphalt pavement. On the other hand, cold-mix asphalt is kept cold during the mixing process.
The new mix is then placed back down on the road as new pavement. Often, recycled asphalt pavement is used as a base or subbase layer for new construction projects.
Some of the asphalt that’s removed during milling can also be used as a base for new asphalt.

What are the benefits of using recycled asphalt?

Most asphalt pavements are removed because they’ve reached the end of their useful life, but it doesn’t mean they can’t be used again. Here are the top benefits of using recycled asphalt:

It reduces the need for mining new materials: Every ton of RAP used in new asphalt pavement saves a lot on virgin asphalt binder, which means that we can use less new material.
It cuts down on emissions: The production of asphalt pavement generates a significant amount of greenhouse gas emissions. Recycling old asphalt pavement reduces those emissions by up to 25 percent.
It’s cheaper than using new materials: It costs less to produce new asphalt pavement from RAP than it does to use virgin materials. In fact, the U.S. Department of Transportation estimates that using RAP can save up to $10 per ton.

Recycled asphalt is good RAP

Recycled asphalt is a popular choice for many reasons: it’s environmentally friendly, cheaper than virgin asphalt, and as strong and durable as new asphalt. Asphalt recycling not only saves money but also reduces waste and helps to sustain our environment. Virgin asphalt material may be requested or required for specific projects but in most cases, asphalt mix containing RAP is generally used for parking lots, driveways, pathways and more.

Holloway Paving uses both RAP and virgin materials. We also haul all excavated, old asphalt to a recycling facility for all of the reasons stated above. Let’s do our part for the environment and keep your budget while updating your asphalt pavement. Call us today for a free quote (403) 975-3030

Asphalt is one of the most widely used construction materials. It’s found on highways and byways, in driveways and parking lots, in playgrounds and recreational areas – even on airport runways.

However, it is also one of the most vulnerable materials to damage from weather, wear and tear, and poor maintenance. Cracks, potholes, and other surface damage can quickly turn a smooth asphalt surface into an unsightly and dangerous mess.

To keep your asphalt surfaces in good condition and extend their lifespan significantly, here are some asphalt maintenance tips that you should keep in mind.

1. Perform routine inspections

Regularly inspecting your asphalt surfaces is the best way to catch problems early on. It’s best to do this at least once a month, but more often if you live in an area with extreme weather conditions where surfaces are exposed to sunlight, rain, hot and cold temperatures, and snow.

During your inspection, look for any cracks, holes, or other surface damage. If you find any, make a note of their location and size so you can repair them as soon as possible.

2. Clean and remove debris regularly

Debris such as leaves, sticks, and garbage can accumulate on your asphalt surfaces over time. This can not only make your property look unkempt, but it can also speed up the deterioration of your asphalt.

To keep your surfaces clean, sweep them regularly with a broom or leaf blower. You should also remove any gum or other sticky substances as soon as you see them. These can be difficult to remove once they’ve hardened, so it’s best to take care of them right away.

3. Sealcoat your asphalt surfaces

Sealcoating is one of the most important things you can do to prolong the life of your asphalt by as much as 30 years.

The process involves applying a special coating to the surface of your asphalt. This coating helps protect the asphalt from damage caused by weather, sunlight, and other elements like oil and gas spills, which can cause cracking and other forms of deterioration.

Ideally, it should be done every two to three years, or more often if you live in an area with harsh weather conditions.

4. Fill in cracks and potholes right away

When you find cracks or potholes in your asphalt surfaces, it’s important to fill them in as soon as they appear. This will help prevent the damage from spreading and becoming worse.

Small cracks can quickly turn into larger ones, so it’s important to nip them in the bud before they get out of hand. Potholes are also a tripping hazard and can cause damage to vehicles, so it’s best to fill them in as soon as they form.

There are various materials you can use to fill in cracks and potholes, such as cold-mix asphalt, asphalt emulsion, or concrete. But for more serious damage such as large cracks or deep potholes, it’s best to hire a professional paving company like Holloway Paving to make the repairs.

5. Resolve drainage problems immediately

If you have any drainage problems on your property, it’s important to fix it immediately to avoid damage to your asphalt surfaces. Standing water can quickly cause surface damage that leads to the formation of cracks and potholes.

It’s best to hire a professional to assess the situation and recommend the best course of action. This may involve installing a drainage system like catch basins or French drains, or regrading the land around your property to ensure proper drainage.

6. Maintain asphalt surfaces during winter

During the winter season, it’s important to take extra care of your asphalt surfaces to prevent damage from the cold weather. Snow and ice can quickly cause surface damage that leads to cracks and potholes, so it’s important to clear them away as soon as possible.

To protect your asphalt surfaces during winter, have a professional apply a sealcoat before the season starts to create a barrier against many elements.
