Protecting your asphalt investment from deterioration is the key to keeping an attractive looking parking lot or driveway. Sealcoating new asphalt within one year of installation is the best and most cost efficient way to avoid expensive repairs due to pavement failures. However, let's take a look at some common asphalt problems and their solutions:
Oxidation and Graying
Over time, traffic, water, gas, oil, the suns unrelenting rays, especially in Florida, will wreak havoc on asphalt pavement. You can browse https://www.joemcasphaltservices.com/concord-driveway-paving/ to know more about asphalt paving.
The older the pavement gets, the more exposure to elements, the more the asphalt pavement will fade and take on a gray appearance. This graying is a sign that the asphalt is oxidizing and drying out.
The drier it gets the more brittle it will become and the more prone to cracking. It's a downward spiral at this point if nothing is done to stop the water from penetrating the asphalt cracks. It is critical that asphalt repairs are made as part of an ongoing asphalt pavement maintenance plan to avoid further decay.
Another asphalt paving maintenance issue to be aware of is raveling. When the binder, which acts as a glue, that is used to hold the stone and sand particles that make up the asphalt starts deteriorating, this is called traveling. Pieces of aggregate will loosen and breakaway from the pavement surface making it thinner and thinner as it deteriorates.
The surface of the asphalt pavement will appear rough as pieces of the asphalt away and separate. This can create a void for water to penetrate into the base material.
Linear Asphalt Cracks
Transverse and longitudinal cracks are fairly common in asphalt pavement as it ages. Starting small, they will expand over time. Again, any crack in asphalt is an opportunity for water to penetrate. Pavement expansion due to hot and cold temperatures will continue to cause the cracks to expand.
