Asphalt is one of the most common types of pavement used in the United States. Luckily, it is also one of the most easily recyclable materials in the country, too. If you have an upcoming project, such as an asphalt parking lot, you might be wondering what materials are used to create this necessary paving material. Let's take a quick look at what goes into making asphalt.

Materials

Asphalt pavement is really a combination of 95% stone, sand, or gravel that has been bound together with asphalt cement, according to the National Asphalt Pavement Association. In some instances, asphalt is even created using other recycled materials. When recycled materials are used to make asphalt, or when asphalt itself is being recycled, you begin to see how truly sustainable this material is.

Binders

In addition to the materials used in the asphalt, there must also be a binder to unite the aggregates together. Aggregates refer to these other materials in the mix, and the binder will create a cohesive mixture. Often, bitumen is used as a binder and contributes to the dark color of asphalt, too. Asphalt is actually made up of a few layers. The layers will consist of bituminous-bound and unbound materials. The lower layers act as a base so that asphalt concrete can then be poured on top.

Types

There are three main types of asphalt that can be used for various projects. The types are hot, warm, and cold. The type of asphalt that is used in a paving project will be based on how the paved area will be used. For instance, an asphalt parking lot at a truck stop will be much different from a driveway for a residential home. When you talk with an asphalt contractor, they will be able to advise you on which type of asphalt you should use for your project.

Quality

Asphalt quality is a big deal. If the asphalt paving you receive is not high quality, it could really affect you financially, and it could create a dangerous safety situation in the future. You might be affected financially if you are required to repair or replace the asphalt very soon. It can affect the safety of the area if cracks and shifting occur. These issues may cause accidents.
