There are many reasons you might want to install asphalt over concrete. Maybe you have a driveway in disrepair, and you’d like to replace it with something easier to maintain.

In general, it is possible to install asphalt over concrete, but there are a few things you need to take into consideration.

First, the existing surface needs to be in good condition and free of any major cracks or potholes. If it is not, the asphalt will not bond properly and could eventually peel away.

Second, the thickness of the asphalt layer will need to be increased to account for the fact that it is going over a harder surface. Finally, installation costs will likely be higher than installing asphalt over an existing gravel driveway.

The Benefits of an Asphalt Driveway

Asphalt is a popular choice for driveways because it is durable, long-lasting, and easy to repair. It is also one of the most affordable driveway materials.

Asphalt is made from a mixture of aggregate and bitumen, which is a black or dark brown substance that is derived from crude oil. It is then compacted to form a hard surface that can withstand heavy traffic. A professional contractor typically installs asphalt driveways, but it is possible to install them yourself.

Why Installing Over Concrete Isn’t Recommended

While installing asphalt over concrete is possible, it is not recommended:

  1. The concrete will need to be in good condition. Any cracks or potholes in the concrete will need to be repaired before the asphalt is installed. Otherwise, the asphalt could eventually crack or peel away from the concrete.
  2. The thickness of the asphalt layer will need to be increased to account for the fact that it is going over a harder surface.
  3. Installation costs will likely be higher than installing asphalt over an existing gravel driveway.

The Best Way to Install Asphalt

It is important to prepare the foundation before laying asphalt in order to avoid having to replace it a few years later. Compacting the soil is one of the most important steps in preparing the foundation for asphalt. This can be done with a hand-held tamper or a plate compactor. The soil should be compacted to a depth of at least six inches.

Another important step in preparing the foundation for asphalt is installing a gravel layer. The gravel should be compacted to a depth of at least two inches.

Once the foundation has been prepared, the asphalt can be installed. The asphalt should be compacted to a thickness of at least two inches.

If you take the time to prepare the foundation properly before installing asphalt, you can be sure that your pavement will last for many years.

Wrapping Up

In conclusion, while it is possible to install asphalt over concrete, it is not always recommended. The asphalt may not adhere properly to the concrete, which can lead to problems with the surface of the asphalt. Additionally, the weight of the asphalt can cause problems for the underlying concrete.
