Advantages of Asphalt Paving

Asphalt Paving is a complex process that transforms rough ground into smooth, drivable roads. It requires meticulous planning, careful preparation, and skilled execution.

Asphalt Paving

Asphalt comprises a mixture of aggregate materials, such as gravel or sand, additives, and bitumen. Bitumen is a sticky byproduct of petroleum and binds the aggregates together.

Asphalt is a great paving material for a couple of reasons, including its environmental benefits. From production and construction to maintenance and recycling, asphalt has a lower impact on the environment than other pavement types. This is because it requires less energy to produce and lay, produces fewer greenhouse gasses, and uses natural resources more efficiently.

The first step in determining an asphalt paving company’s green credentials is how they handle their materials. The best asphalt paving companies use recycled materials whenever possible, which reduces the need for new roadbuilding and saves on transportation costs. They also use eco-friendly tools to test the quality of their products, such as handheld spectroscopic devices, x-ray fluorescence spectroscopy, and Fourier transform infrared spectroscopy. This enables them to do spot tests in the field without having to take samples back to the laboratory.

The next thing that asphalt is known for as a ‘green’ material is how it can be used over and over again to save on the need to harvest fresh, raw materials. In fact, asphalt consists of recycled and reused aggregates such as rock, sand, and slag. Because of this, tearing up old roads isn’t a destruction process but more of a reconstruction. In addition, the reusable components of an asphalt road can be recycled to be used in future paving projects.

As an industry, asphalt is committed to continuous research and development of environmentally friendly technology. This includes developing warm and cold asphalt mixes that allow it to be laid at lower temperatures. This not only reduces emissions but also cuts heating costs and worker exposure to heat. It also allows the paving season to be extended into colder areas.

Other environmental advancements include the use of permeable asphalt, which helps to filter rainwater and reduce demand on storm sewer systems. In addition, porous asphalt is designed to let rainfall soak into the ground to replenish water tables and aquifers. This also helps to alleviate flooding and erosion problems in local areas. Lastly, the smooth surface of asphalt pavements reduces rolling resistance which in turn improves fuel efficiency and results in quieter, more comfortable rides.


Asphalt paving is a great option for roadways and parking lots because it is very durable. It is also easy to maintain and repair. The key to a long-lasting asphalt pavement is the quality of the materials and construction process. Great paving contractors pay attention to detail and use the latest technology and equipment to ensure that their work is done correctly the first time around. This helps to prevent costly mistakes and gives the end result a high level of performance and value.

Having quality asphalt is important because it can take on a large amount of traffic without damage or premature deterioration. Asphalt paving can last up to 20 years or more depending on the amount of traffic and climate conditions. In addition, asphalt is a green paving solution as it uses recycled materials and produces less greenhouse gasses than concrete or other surfacing products.

When it comes to quality asphalt, there are five keys that a contractor should keep in mind throughout the entire construction process. These keys are grading, compaction, air voids, asphalt mix design, and in-place density. These five factors can have a significant impact on how long and well an asphalt pavement will last.

The first step in making a good quality asphalt pavement is preparing the surface. This includes removing any existing material and grading the area so that water drains away from the pavement. Next, the contractor should lay a sub-base layer to support and load-bear the asphalt. The sub-base is typically made from aggregate materials like crushed stones and gravel.

After the sub-base layer is installed, a layer of hot mix asphalt (HMA) is placed on top. The HMA is a combination of aggregate and liquid asphalt cement that is heated and combined before being applied to the road surface. The final layer of asphalt is the surface course that is usually made from a mixture of larger aggregates and finer material.

Finally, the air voids in the asphalt must be reduced to improve its durability. This can be accomplished by either reducing the amount of aggregate or by using an air void control additive to the HMA mix.

Easy to Maintain

Asphalt is a durable material that can easily be maintained with proper care. The key is a preventative maintenance plan. Regular sealcoating and crack filling will keep your asphalt looking new and strong. By performing these simple tasks regularly, you can avoid the costly repairs and resurfacing that can occur when the surface is neglected.

It is also important to keep in mind that proper ground preparation is critical for a long asphalt life. This can be done through proper site planning, excavation and ground compaction. In addition, it is important to have the right materials for your paving project. These may include an aggregate base or an asphalt mix. The best option for your paving needs will be determined by the type of traffic you will be seeing on the area and how it is going to be used.

Another way to help your asphalt last longer is to ensure that it is properly drained. Standing water can damage the asphalt and cause potholes and cracks. Make sure that you have a drainage system installed for your parking lot and check that it is functioning properly.

In terms of repairing your asphalt, it is important to repair small cracks as soon as you notice them. Cracks left untreated will allow water and chemicals to penetrate the asphalt base, which will lead to severe damages that require expensive repairs. Small cracks can be repaired with a rubberized asphalt-emulsion crack filler. If the cracks are wider than two inches, they can be filled with an asphalt cold patch mixture.

The noise pollution caused by vehicles is also a major factor in the wear and tear of your asphalt pavement. A study found that the amount of damage caused by a vehicle is proportional to its axle load raised to the fourth power, which means that doubling the weight of a vehicle causes it to cause 16 times as much damage.

One way to reduce the amount of noise pollution generated by cars is to choose an asphalt mix with low granule content and high binder content. This will allow the granules to stay together and provide a smoother driving surface. In addition, a good quality noise control product can be added to the mix.


Asphalt is a cheaper and faster paving material than concrete. It is also easier to install, and less labor intensive. It is easier to repair than other paving materials, as well. This makes it a cost-effective option for homeowners and businesses alike.

During the construction process, asphalt is much more efficient than other options. It is able to be constructed in short windows of time and can be ready for traffic as soon as it has been compacted and cooled. This helps minimize road closures and saves traveler and business owners thousands of dollars in user delay costs.

The process starts by mixing aggregates such as gravel, crushed stone and sand in a heated binder. This mixture is then combined with liquid asphalt cement and mixed thoroughly on-site in a drum or a mixer truck. This asphalt is then placed on the desired surface and smoothed down using a roller. The result is a smooth, even and durable surface that can withstand heavy vehicle traffic for years to come.

Most asphalt paving projects require a base coat of 8-10 inches of gravel to give the asphalt stability and protect it from cold winter temperatures. This foundation step is an additional cost that varies according to the quality and amount of time spent applying it. However, many companies offer a more cost-effective option of recycled or reclaimed asphalt pavement (RAP) for the base coat, saving money on new materials while helping to reduce landfill waste.

Once the base coat is applied, the project is almost complete. Some areas may need drainage design to help prevent water erosion over the course of time. A good contractor will be able to assess these needs and recommend solutions.

The next step is to lay down the asphalt itself. Once it has been spread, the surface is smoothed down and rolled with a special machine. This helps to ensure an even and smooth surface for vehicles, pedestrians and skaters to enjoy.

Asphalt’s water drainage capabilities are very important. They help to redirect water that might otherwise build-up under the pavement and cause heaves. This helps to avoid costly repairs and maintenance work in the future.
