Paving Asphalt the Right Way

Asphalt Paving Charleston SC requires an experienced crew and equipment. Paving Companies maximize productivity through the best paver operation and maintenance techniques.


The aggregate components of an asphalt mix are weighed with a belt weighing instrument and dried by rotary dryers. This step is critical to ensuring the blend meets design specifications and has adequate stability.

Paving asphalt is a great way to provide a durable, attractive surface for roads, parking lots, and driveways. But before any paving can take place, the area must be properly prepared. This step is important because the proper foundation for your asphalt surface will determine its longevity and performance.

After ensuring that the sub base layer is in good condition, it’s time to add the binder layer. This is made of large aggregates mixed with oil and makes your new asphalt surface strong, resilient, and durable. This layer also helps your asphalt stand up to the elements and heavy traffic.

Once the binder is in place and any soft areas have been addressed, it’s time to lay down the top asphalt layer. This is composed of small aggregates like sand and oil. The combination creates a jet-black asphalt that provides a smooth, attractive surface and a safe ride for vehicles.

This is one of the most important steps in the process. It’s vital to ensure that the asphalt has been poured evenly, compacted, and smoothed. This will help prevent rutting and other problems later on in your pavement’s life.

TFHRC has developed a number of methods to test asphalt for quality, including the use of handheld spectroscopic devices that allow asphalt paving contractors to quickly analyze samples without having to transport them back to a lab. These tools can detect the presence of REOB, as well as lime and styrene-butadiene rubber polymers.

Another important step in the preparation of an asphalt pavement is to verify that the soil under the surface can support the load of a structure or structure built on it. Failure to do this can result in a pavement structure that sinks or buckles under the pressure of traffic and weather conditions.

Finally, any transitional areas between the new asphalt and existing roads, parking lots, or driveways must be graded and compacted to make sure that they’re strong enough. This is also when butt joints are installed to ensure a smooth transition and proper water run-off. Once the transitional areas have been taken care of, a proof roll is used to secure and seal the underlying asphalt surface.

The proper mixing of paving asphalt allows it to meet the required stiffness, resistance to deformation and durability. Various types of mixes can be made to suit different requirements such as traffic volumes, weather conditions or noise reduction. The mix needs to be able to support the heavy weight of vehicles while maintaining good traction. Aggregates vary in size, gradation, hardness and toughness, which is why careful selection and blending is so important for achieving the right mix type. The aggregate must also be properly connected by asphalt binders to ensure the finished product can resist varying pressures and movement.

The mix is heated and thoroughly blended with additives such as recycled materials, emulsions, or polymers to achieve the desired consistency and performance. These additions help minimize asphalt binder drain-down and improve mix stability, workability and durability. The mix is tested for its temperature, density, and particle size distribution before it is loaded into trucks to be delivered to the job site.

Once at the jobsite, the material is placed on the road by specially designed equipment. The hot asphalt must be compacted to the correct density (145 lb/ft3) in order to prevent future cracking and failure of the pavement. The compaction process can be assisted by vibration or mechanical tamping.

Hot mix asphalt, also known as HMA, is the most widely used paving material in the country. It is produced by heating a mixture of aggregates, binders, and fillers to temperatures between 300 and 350 degrees Fahrenheit in the plant. This creates a viscous liquid that can be poured over the aggregate and then crushed, mixed and distributed by the paver for construction.

Another popular option is cold mix, which does not involve any heating of the aggregate and is usually used for patching and repairs. The mix is created by emulsifying asphalt in water before it is mixed with the aggregate. The result is a less viscous material that requires fewer fossil fuels for production, and that can be spread and compacted manually.

Governmental transportation agencies and contractors have recognized that traditional prescriptive mix designs were not delivering pavements with the required performance. A new method of designing HMA mixtures called balanced mix design has been developed to replace this approach. This new design incorporates the rutting and fatigue test results of the Hamburg and Overlay Tester with the lab molded density and aggregate stockpile specific gravity of the mix in order to predict performance and determine its suitability for a particular application.

When it comes to paving asphalt, compaction is one of the most critical phases. Achieving a certain asphalt density allows the pavement to resist damage caused by traffic and weather elements over time. However, the process of achieving this asphalt density involves more than just using the right equipment. It also requires a great deal of attention to detail.

The first step in ensuring proper compaction is to ensure that the new layer of asphalt is still warm enough for compaction. The asphalt-concrete mix should never be allowed to cool down below a temperature that can’t be reoriented by the compaction equipment into its densest configuration. This compaction cutoff temperature is typically 175 F or higher.

This is why it’s important to keep an eye on the temperature of the asphalt mixture during the laydown and roller compaction stages. In addition to the temperature of the mix, a contractor must consider the base temperatures of the existing pavement and the ambient air. This is because the temperature of the base and the ambient air affect how fast the HMA cools.

After the pavers finish placing the new layer of asphalt, the crew then uses a series of mechanical compaction passes with pneumatic tire or vibrating plate rollers. These rollers are designed to help increase the density of the pavement. However, it is important to note that the type of roller used must be appropriate for the size of the aggregate used in the mix. If a large roller is used on a small aggregate, the compaction force may be insufficient to achieve the required density.

The sequence, speed, location, and pattern of the roller passes can have a profound impact on the ability to achieve asphalt compaction targets. This is especially true if the mat temperature is low and the roller passes are made too quickly.

Another important factor that can influence the ability of a contractor to achieve compaction targets is wind velocity. A high wind velocity will cause the HMA to cool more quickly than a low wind velocity. It will therefore take less time for the material to reach a temperature that can be reoriented by the compaction equipment and the rollers.

The rolling of asphalt is a critical part of the paving process. When done correctly, it can lead to a pavement layer with high density and long-lasting durability. Properly regulating the temperature of the mix, using a roller with the proper size and type of tires, and maintaining a consistent rolling pattern are all important aspects of the asphalt compaction process.

Vibratory and static rollers are both essential paving tools for asphalt construction. Depending on the project, these tools may be used alone or in conjunction with a paver to achieve desired results. When choosing a roller, contractors should consider the size and type of surface they are building, as well as the budget for the project.

When the paver is in motion, the rollers must follow suit, or the resulting asphalt surface will have inconsistent quality and density. The best way to ensure a consistent and precise roller rolling pattern is to train the operator before the job starts. During training, the operator learns how to read the paved area and maintain the proper speed. In addition, the contractor should use a nuclear density gauge during paving to measure compaction as it occurs. This is an important step to help identify areas of over-compaction and determine if additional paving steps are necessary.

Ideally, an HMA should reach an air-void content of 3% to 8% during the compaction phase. This can only be achieved by using the right amount of pressure from the rollers and a correct sequence of operations. Breakdown rolling is often done first, followed by intermediate and finish rolls. The breakdown roller should have a drum width that is equal to or greater than the paver’s layout. This ensures uniform coverage of the paving panel.

The TFHRC is working on a new method of looking at the compaction of asphalt. By measuring the viscoelastic properties of an asphalt sample, researchers can identify what materials were added to the mix during blending. This information can then be used to improve the performance of asphalt mixes and reduce rutting. The process also allows for a better understanding of how shear stresses impact the underlying layers of an asphalt pavement.

Advantages of Asphalt Paving

Asphalt is the pavement of choice for many commercial parking lots and roads. It has a professional appearance that helps to make your business look good.

Asphalt Paving

The main ingredients in asphalt are aggregates and bitumen, which bind the aggregates together. Various recipes can be mixed and then heated to form the hot asphalt mix used for paving. For professional help, contact Asphalt Paving Fort Lauderdale now!

Asphalt is a popular choice for paving because of its strength. It is resilient enough to withstand heavy traffic and weather and will not disintegrate easily over time. The main strength of asphalt comes from its ability to absorb and transfer loads. This is achieved by squeezing the aggregates together to create a dense mass that can support large amounts of weight. This gives asphalt pavements a strong structural design, which is especially important for busy roads and highways.

When comparing the strength of asphalt to concrete, it is important to look at the thickness of each type of pavement. A concrete pavement requires a minimum of four inches for an acceptable surface while asphalt is much thinner, requiring only two or three inches in most applications. However, even though asphalt is thinner than concrete, it still provides the same traffic-carrying capacity at the same thickness. This is because both materials provide a high traffic-carrying strength per inch of thickness.

Unlike other forms of paving, which must be compacted by hand, asphalt is mechanically compacted using an asphalt paver. The machine agitates the mixture and uses multiple layers of compaction rollers to pack it down into its maximum density. This is essential for high-traffic applications because it helps to keep the pavement stable and prevent damage to the subgrade.

The asphalt used in paving is typically made by heating bitumen and mixing it with aggregates in a large mixing drum or tank. The resulting mixture is then transported promptly to the paving site and poured while it is hot.

This mix is known as a hot mix because the asphalt and aggregate are heated to 350 degrees Fahrenheit before it is poured. It is the most commonly used mix for paving residential and commercial driveways, sidewalks and parking lots. Hot mixes are also used to build high-traffic roadways, interstates and highways.

Traditionally, most asphalt testing has focused on engineering properties such as stiffness. Researchers at TFHRC are developing handheld spectroscopic instruments that can determine what is in an asphalt mixture without the need to take a sample back to the lab. For example, an instrument called a x-ray fluorescence spectrometer can detect REOB (recycled extended oil base) and phosphoric acid as well as other additives like lime, copper and zinc.


Asphalt is durable, which makes it ideal for roads and parking lots. It can withstand heavy traffic and extreme weather conditions without breaking down. It can even last a few decades before needing to be replaced. It is a very affordable option for long-lasting pavements.

Asphalt paving is made from many ingredients that are combined and heated to create a strong, flexible material. The most important ingredient is bitumen, which holds the aggregates together. The mix also contains clay, sand and other substances to add traction and strength. The final product is rolled and compacted for a smooth surface that can be driven on safely.

The durability of asphalt depends on how it is installed and how much traffic it receives. It requires proper installation and the use of quality materials to ensure longevity. Proper installation includes making sure that the soil is well drained, and that it is properly compacted after the layer of asphalt is applied. The thickness of the layer is also an important factor in durability. The type of asphalt used can play a role in its longevity as well. Different mixes can be designed for specific applications to meet the needs of different climates and traffic levels.

Durability is also determined by the temperature of the environment in which it is placed. Extreme heat can cause the asphalt to soften, which can lead to rutting in some instances. Cold temperatures can cause the asphalt to shrink, which can also lead to cracking.

To avoid these issues, it is recommended to use high-quality asphalt mixtures that have been tested for their stability and durability. A good way to test the durability of an asphalt mix is to perform a wheel-tracking test or a dynamic modulus test. These tests are able to measure the structural integrity of an asphalt mixture, as well as its ability to resist damage from traffic and temperature changes. The results of these tests can help to determine the best asphalt for a particular project. The results of the tests can be compared to the requirements for various specifications, including the rutting resistance, temperature fatigue and water damage test.


Asphalt pavement is very flexible, which makes it easy to repair and maintain. It can be adjusted to accommodate different traffic loads and environmental conditions. This flexibility is a result of its layered structure that distributes stress over the subgrade. In contrast, rigid pavements rely on concrete flexural strength and are sensitive to temperature changes.

When paving with asphalt, it is important to choose the right mixtures to meet the project requirements. For instance, high-traffic roads and parking lots with heavy traffic require an asphalt mix that is both stiff and resistant to distortion. It also needs to have adequate flexural strength that prevents damage caused by varying pressures on the pavement surface. It is essential that the asphalt mix can be worked easily during application, and it must be compacted to achieve optimum durability.

The asphalt paving process requires a number of tools and equipment to ensure proper and efficient completion. The first step is to remove the existing pavement and prepare the site for laying the new asphalt. Then, the asphalt mixture is placed on the ground using a specialized paving machine called a paver. This machine has a conveyor system that transfers the material from the hopper to the screed plate. The conveyor system is designed to allow for different materials depths, widths, and grades. It is a critical component of the asphalt paving process because it determines how smooth and even the finished product will be.

Once the asphalt mixture is placed, it is compacted by a mechanical roller. The compacting process takes about 15 minutes per inch of pavement. After the asphalt is thoroughly compacted, it is graded to ensure proper drainage and slope. This ensures that water will flow away from the paved area and not pool on it, which can damage the structural integrity of the road or pavement.

The grading process is also crucial to prevent water from collecting in the cracks of the asphalt. This can cause them to erode and crack over time, leading to permanent damage. To avoid this, it is important to have a professional inspect the job and perform any necessary maintenance before it becomes too serious.

Ease of Maintenance

Asphalt is a popular surface material for roads and parking lots because it offers many benefits that help reduce maintenance costs and keep your property safe for both vehicles and pedestrians. Some of the most important advantages that asphalt provides are a smoother and safer ride for drivers and good drainage to reduce flooding and water runoff. Asphalt is also able to withstand weather elements such as snow and rain more easily than concrete.

While a new asphalt installation does require some initial maintenance, it is significantly easier to maintain than other surfaces such as concrete or gravel. In addition, asphalt is recyclable, which helps to reduce the amount of waste and preserve natural resources.

Unlike concrete, which is poured directly into place on the ground, asphalt is mixed with a binding substance and then laid over it. The asphalt is then compacted with heavy machinery such as rollers and a paver, which results in an even and durable surface. Asphalt paving equipment is designed with precise specifications to ensure that the pavement has proper density and strength. This enables the equipment to be operated at high speeds, which allows for faster and more accurate placement.

A great asphalt contractor will have complete quality control measures in place to ensure that the finished product is high-quality. This begins from the moment the aggregate materials are collected and processed. All of the aggregates are carefully sized to resist early wear and all the bitumen used is derived from fully refined petroleum products. A proper grading and drainage system is also in place to help manage water runoff and flood risks.

The best asphalt paving contractors will use state-of-the-art technology and machines to provide you with the highest quality pavement possible. The machines are specialized to ensure that the asphalt is laid and compacted correctly without any aggregate segregation, resulting in a strong, durable surface that will last for years.

Asphalt is an eco-friendly, versatile material that can be shaped to meet the unique needs of your road or parking lot. Its water managing qualities help to prevent cracks that can lead to damage over time, and its dark color helps to melt ice and snow more quickly than other surfaces. Regular maintenance checks will identify any problems and allow your paving contractor to make the necessary repairs as soon as they are needed.

Asphalt Services You Need To Know

Asphalt can be durable, but that doesn’t mean it will never need repair. Regularly performing small maintenance tasks can keep your asphalt surface looking great and functioning properly.

Weeds, oil and chemical spills, drainage problems, and standing water should be tended to right away. If left unchecked, these can lead to larger issues that will require costly repairs.

Seal Coating

Seal coating is a process that transforms faded asphalt to an almost brand-new look. It also protects the asphalt from damage by UV rays, water, oil, chemicals, and traffic. It also helps fill small cracks and voids that may otherwise cause the asphalt to deteriorate quickly. It’s a cost effective way to keep your pavement in good condition, and it extends the life of the asphalt.

The process of seal coating consists of applying a liquid product to the surface of the asphalt. This product is then rolled or squeegeed onto the asphalt to create an even and thick layer that seals the surface, and fills in any small cracks. The pavement then gets a dark and rich appearance that is appealing to many property owners.

Before the seal coat can be applied, it’s important to ensure the pavement is clean and free from debris. Any potholes and cracks need to be filled with asphalt or patching material, and any vehicle fluids like oil should be removed. Once the surface is ready, it’s best to allow for a few hours of dry weather, and barricade the area to prevent access while the seal coat is drying.

The seal coat itself is composed of bituminous or acrylic based products, along with water, silica sand, and additives. These ingredients are mixed in a proportioning formulation that’s called a mix design, and it varies depending on the manufacturer of the sealcoating product. The mix design will also vary according to the pavement condition, traffic frequency, and age.

Choosing the correct type of asphalt sealcoat is important. Refined coal tar is the standard for most sealcoats, as it provides a high level of protection and a durable deep black finish. However, it does not offer resistance to petrochemicals such as gasoline and oil. It’s also known to be toxic to humans and animals if not properly ventilated during application.

For this reason, a majority of contractors are now using asphalt emulsions, which are less toxic and easier to ventilate. These types of emulsions have been shown to be more environmentally friendly, and they also offer superior performance and durability compared to traditional coal tar sealcoats.


Crack sealing uses rubberized products to stop water infiltration and protect the longevity of your asphalt. This pavement repair is effective for non-working cracks that don’t show significant movement over time and can be done for a fraction of the cost of replacing a section of asphalt.

Asphalt cracks aren’t just unsightly; they can also let water in and erode the base, leading to a variety of problems including rutting, shoving and depressions. Crack sealing prevents moisture and debris from entering these cracks and deteriorating the base, and should be performed before cracks get out of hand.

When performing crack sealing, it’s important to clean out the cracks with a blower or compressor set at a minimum of 90 psi. This will avoid dirt from one crack being blown back into cleaned cracks. Cracks should be prepared by routing or saw cutting to create a reservoir, which will allow the sealant to adhere better to the sides of the crack. Cracks should be sealed when the pavement is warm, but not hot. This allows the sealant to expand and contract with the temperature changes, rather than forming a hardened, brittle crack.

Pavement damage is often the result of a number of different factors, including distortions (rutting), environmental and climate influences, traffic loading, or cut corners in the initial installation. A slurry seal can be used to repair these types of damages, although it will only offer a short-term solution.

It’s important to visually inspect your pavement every year to identify any new cracks that may need to be filled or sealed. Annual inspections can also identify if existing cracks need to be re-sealed or repaired.

There are a variety of crack filling placement configurations, such as flush fill, overband or reservoir, but the key to successful application is the correct wand tip. The proper wand tip ensures the crack fill is placed at the bottom of the crack, so that it doesn’t push up through the top layer of pavement. It’s also essential to use the right crack sealant for your type of pavement.


Asphalt is one of the most durable materials used for road construction. This makes it a viable option for commercial parking lots and driveways. However, it can still suffer from severe damage if not properly maintained and repaired. It is important to hire an experienced team to take care of your asphalt surfaces. Here are the services you can expect from a reputable contractor:

Asphalt Pavement Repair

Asphalt repair should start with a full inspection of your pavement. A dependable contractor will check for any structural problems like rutting, shoving and depressions. They will also look for distortions in the surface like buckling or warping. This typically occurs when the base layer is compromised due to a lack of support or improper installation in the first place. It can be exacerbated by the use of heavy vehicles in the area such as trash trucks or tractor trailers. This type of damage can lead to costly repairs such as a complete resurfacing or even a total replacement.

Cracks are another common cause of asphalt deterioration. These should be addressed right away as they can continue to widen over time if not treated. Some types of cracks are easier to fix than others. For example, alligator cracks are shallow surface defects that resemble the skin of an alligator. These can usually be repaired with an asphalt crack filler. Other cracks require a more extensive repair such as an overlay or complete replacement.

Other structural problems with your asphalt surfaces include sinkage or heaving. These issues are often caused by water and heat eroding the binding agents in the asphalt. They can also be the result of chemical spills and stains that continue to sink into the pavement until they are addressed.

A good asphalt service provider will also offer preventive maintenance solutions. These can be done on a regular basis to slow down the deterioration of your surfaces. For instance, they can apply an asphalt sealant to protect the surface from UV rays and heat and to prevent water damage to the sub base. This helps extend the lifespan of your asphalt surfaces by several years. They can also treat minor surface imperfections like alligator cracks, potholes, reflective cracks and oil spots.


Asphalt has some very interesting properties that make it a highly effective pavement material. It can withstand heavy loads, it can be used for different purposes and it has an excellent lifespan that’s longer than most other materials. Despite its durability, this material is still subject to wear and tear, which means it’s important for owners and managers of commercial property to understand the different asphalt services available to them.

Asphalt maintenance includes everything from repairing small areas of damage to resurfacing the entire lot. It’s also essential to regularly sealcoat asphalt, which protects it from weather damage and other deteriorating factors. By performing these important asphalt services, you can help ensure your commercial property’s asphalt surfaces last longer and look better.

It’s important to find a reliable and trustworthy asphalt service provider. This is why you should ask for references from past clients and read reviews online before deciding which company to hire. You want to be sure the company you choose is experienced and can provide top-notch workmanship.

A quality asphalt service can help you save money in the long run. Whether you need to repair potholes, smooth your parking lot or restripe faded lines and directional markings, it’s worth the investment. Not only will it improve the safety standards of your business and property, but it will also show customers and tenants that you care about the quality of your property.

When choosing an asphalt service provider, be sure to find out if they are familiar with the local climate and terrain. This way, they can offer options that are best suited for your location and the conditions it faces. You should also ask for examples of their work and what kind of results you can expect from them.

The most common type of asphalt damage is what’s known as “fatigue cracking.” This involves jagged and interconnected cracks that resemble alligator skin. This type of damage can be caused by increased traffic, environmental or climate influences or simply cutting corners in the initial installation. If left untreated, this type of damage can weaken the subgrade, leading to costly repairs like BST overlays and full depth patching.
