An asphalt surface may crack as it is used. However, while you cannot prevent every single crack in this type of surface, there are steps that can be done to minimize the amount of cracks that may develop in your asphalt surface. Here are a few of the common reasons why asphalt surfaces may crack and what you can do to minimize this issue.
An Improper Asphalt Thickness
One of the reasons why an asphalt surface may crack is because the asphalt is not thick enough for the conditions in which you are subjecting it to. When you are having asphalt paving done, you need to be honest with the contractor about the conditions your asphalt road or surface will be subjected to. An asphalt surface that is just being walked across will not need to be as thick as one that heavy trucks are being driven across. If you misrepresent the amount of traffic or weight of the traffic, a contractor may make the road thinner, and it can crack if exposed to different conditions.
Not Using a Seal Coat on Your Asphalt Surface
The other common reason why asphalt may crack is because the asphalt surface is not seal coated. Asphalt is a porous material. When it rains or sprinklers drip water onto the surface, the asphalt absorbs the liquid. Imagine what happens to a sponge as it absorb liquids. It begins to expand. The same is true of asphalt. It begins to expand and as this happens, it can crack. Seal coat can be placed on the asphalt surface to fill in the pores and prevent the surface from absorbing water.
However, seal coating the surface once is not enough to prevent cracking. A seal coat will need to be reapplied as the old seal coat wears off to keep the asphalt surface from absorbing water. The amount of traffic your asphalt surface is exposed to and the weather conditions it is exposed to will determine how frequently seal coating will need to be applied in order to best protect your asphalt surface from cracking.
An asphalt paving professional can help you determine what thickness of asphalt is best for your surface and apply a seal coat to your paved surface to protect cracking. However, despite your best efforts, you cannot prevent all cracks from forming. If your asphalt surface does begin to crack, you will want to have the crack filled as quickly as possible to prevent more extensive damage.
