Asphalt Paving Improving the Condition of Driveways

Asphalt is a composite material used on driveways, parking lots, airports, and other roadways. Asphalt concrete is made up of mineral aggregate, which has been adhered to a binder. This type of paving style has gained popularity due to its reliability that over 90% of parking areas in the U.S. have asphalt pavement, which is the material of choice for most development owners. Therefore, asphalt paving has a great future in the development field.

Types of Asphalt Concrete

Various kinds of asphalt concrete used on pavements exist, and they include:

1. Hot Mix Asphalt Concrete (HMA)

This type of concrete is made by drying the aggregate to remove moisture from it and then heating the binder to decrease its viscosity. The binder and aggregate are mixed at 95 to 150 °C depending on the aggregate used, which can be virgin asphalt, asphalt cement, or polymer asphalt cement.

Paving is done when the concrete is still hot. This concrete is usually used in the summer because, during winter, the compacted base will cool the concrete. This concrete is used to pave major highways, airfields, and racetracks.

2. Cold-Mix Asphalt Concrete

The cold mix-asphalt concrete is made by emulsifying the asphalt with soap before mixing it with the aggregate. Emulsion lowers the viscosity of the asphalt, making it easier to be used. The emulsion will break after the water has evaporated from the mix, and at this point, this concrete will have the same properties of HMA. This concrete is used to pave less is trafficked service roads.

3. Warm-Mix Asphalt Concrete

Abbreviated as WMA, this asphalt concrete type is produced by adding either asphalt emulsions, waxes, zeolites, or water to the binder before mixing it with the aggregate. This mixture allows paving to be done in lower temperatures, and in turn, lower consumption of fossil fuels.

4. Cut-Back Asphalt Concrete

This is a form of cold mix asphalt, but first, the binder is dissolved in kerosene and another lighter type of petroleum before mixing it with the aggregate. After laying the mixture down, the lighter type of petroleum will evaporate.

5. Mastic Asphalt Concrete

Also called sheer concrete, it is made by heating bitumen in a mixer until it becomes a viscous liquid, and then the aggregate is added. The bitumen should be partly oxidized. The mixture is then transferred to the construction site and laid to the desired thickness.

6. High- Modulus Concrete

This type of asphalt mixture is produced using a tough bituminous formulation. The unique part of this concrete is that it is modified in a proportion close to 6% to the aggregate weight and 10% to mineral powder making asphalt concrete with a high modulus of elasticity.

7. Asphalt Pavement Installation

Now that you have information on the types of asphalt concrete, it is important to discuss the pavement installation methods. First, the existing surface is demolished and removed, but if it is asphalt concrete, it can be recycled to save on money. Recycling is usually common during driveway resurfacing.

During asphalt paving, before anything is laid down, the surface is thoroughly checked to remove water. A sub base is then laid, and the asphalt mixture is rolled using machines.

Advantages of Asphalt Paving

Paving solutions that have been brought about by asphalt paving are breathtaking. One of the advantages is flexibility. Cracking is a problem faced mostly by commercial paving, as many people use that particular roadway. Asphalt paving is durable and flexible, and thus, it is not prone to cracking.

Also, it is cheaper than other concrete types. Asphalt services are affordable, and that is the reason residential paving services are on the rise. Moreover, asphalt paving sets by cooling, and not curing, which means, its setting is fast, and thus receiving asphalt services save on time.

Residential and commercial paving services are on high demand, which has made development companies come with better solutions such as asphalt paving. This guide offers in-depth information about asphalt paving. Asphalt services are being provided enormously due to the advantages that they provide.

Aspects to Consider for Asphalt Paving

Asphalt pavements are a great choice for your driveway or parking space because they look appealing, last longer, and can be installed quickly. A study shows that smooth pavements increase pavement life anywhere from 10 to 25 percent and at the same time, result in lower maintenance costs. It also good for your budget and the overall environment, and these are why asphalt paving solutions are so popular around the world.

Now that you know about the benefits of asphalt pavements, what are some of the aspects to consider while laying these pavements?

Selecting the Right Contractor

An important aspect is to choose the right commercial or residential paving services. The technicians should be experienced and knowledgeable, and they should be able to pay attention to the smallest of details to give you a smooth and lasting pavement.

While selecting contractors, make sure you get some references, talk to many residential paving services, and do some background research before deciding on a contractor. All these aspects are sure to lead to the good pavement.

Structural Design

While building pavements, ensure that the structural capacity can carry the loads and traffic. The subgrade is the foundation for your pavement and it should be free of topsoil or vegetation. This subgrade should also be molded to match the final contour of the pavement.

The next is your aggregate. Ideally, you need about six to eight inches of crushed aggregate for residential pavements and more for commercial ones. This should be followed by a dense-graded HMS base that should be approximately two inches thick. If the pavement is going to see heavy traffic, you should increase this thickness.

This is the broad structural design that can give you a strong and lasting pavement. Of course, you can also check with a commercial paving services company, as they can guide you better.


Drainage is another essential aspect for the longevity and performance of your pavement. You have to ensure that water doesn’t enter the subgrade because it takes a long time for water to evaporate from this layer, even during hot summer days. Over time, this will weaken the subgrade and can lead to the cracks in your pavement. To avoid all these problems, ensure that you have a proper system to drain water from the pavements before it seeps into the subgrade.


There are many types of HMA mix available and you should work closely with your residential paving services company to identify the right mix that would work well for you. Also, ensure that the asphalt services company buys the HMA mix from a reputed local producer.


The subgrade should be stable and the soil should be well-compacted before you begin construction. This will give the right shape for your pavement. Also, make sure that you do paving when the weather is good.

Thus, these are some of the aspects you should consider for asphalt pavements.
