Simply put, Asphalt is a material for building pavements. It is made from a few different materials, which include stones, sand, and gravel. These components of asphalt are all held together by asphalt cement.
This combination of material and cement creates a smooth surface. This surface helps our cars in several different ways. The cars are consuming less fuel since the surface is smooth. Less fuel consumption also means this helps lower emissions plus it’s quiet. A quiet road removes the need for expensive noise reducing walls to be built. Asphalt provides excellent gripping power, but most importantly it is durable. On top of all this asphalt happens to be one of the most recycled materials in the USA.
Where can Asphalt be used?
Most commonly it is used on projects such as road surfaces, parking lots, and airports. The trick is in knowing what type of asphalt to use for a given project. Different types of asphalt have different performance characteristics. These are generally measured in roadway noise, braking efficiency, tire wear and surface durability.
What if the Asphalt deteriorates? What about Restoring Asphalt?
When we see asphalt deterioration this generally comes in the form of rutting, depressions in grade, potholes and upheaving. In colder climates frost heaving can occur when the groundwater freezes and expands thus cracking the asphalt.
In general there are three different factors or categories that impact asphalt: construction quality, environment, and load from traffic. Typically damage occurs when all three of these are combined. For example, in Texas we see very high temperatures. With high temperatues the asphalt binder may become softened which allows heavy tire loads to press in the asphalt thus deforming the asphalt by leaving ruts. I am sure you have driven down the high way and seen these ruts in the right lane. Since heavy trucks travel in the right lane often all year the right lane tends to have these ruts. Water under the pavement can do the same thing which leaves the road vulnerable to traffic loads.
The life of asphalt can be prolonged through proper construction, design, and general maintenance. Engineers will often times measure the traffic on the road to evaluate how much the road can withstand. Then thickness is applied depending on the evaluation. As for maintenance, well, that involves keeping the water out of the pavement and various layers under the asphalt. Simple ways to do this is to clean storm drains, which will extend the life of the road. Whenever we see standing water then there is certainly chance that that road is going to start degrading.
