What Causes Asphalt Pavement to Fail?

Assuming that the initial asphalt pavement was designed and constructed properly, the primary cause of failure is the penetration of water into the asphalt base.

This process begins with the oxidation of the pavement surface which caused the asphalt to dry and become brittle, this leads to the erosion of the top layer of fine particles and the appearance of larger stones and small cracks on the surface.

If left untreated these cracks grow over time and eventually allow water to penetrate to the base of the pavement. When water enters the base of the pavement the base material moves and settles leading to further cracking and an “alligator appearance.”

When the pavement reaches this stage the only option is removal and replacement of the old asphalt.
