What Causes Asphalt Pavement To Fail?
Assuming that the initial asphalt pavement was installed properly, the primary causes of failure are the penetration of water into the support base as well as ground shifting. Sun oxidation of the pavement surface causes the asphalt to dry and become brittle making it more susceptible to erosion of the top layer as the minerals and oils that bind the aggregate diminish. This breakdown will lead to surface cracking and further pavement failures.

​If left untreated, these cracks grow over time and allow water to penetrate the base of the pavement. Water will shift the base which can lead to additional cracks, low spots and damaged areas.

When the pavement reaches this stage, it is crucial to protect your investment and repair the asphalt.
