Fatigue cracking is typically the result of heavy traffic, a lack of needed repairs, or poor construction of the asphalt surface.
Every asphalt surface can handle a certain amount of pressure. A strong foundation is critical to allowing the surface to bear pressure and traffic. When an asphalt surface is placed under too much pressure, from either heavy traffic or repeated use, then fatigue cracking can set in.
Once alligator cracking in pavement has occurred, water can seep into the pavement, degrading the foundation and ground beneath. This, in turn, causes more alligator cracking, which then allows even more water to seep into the pavement. This vicious cycle can lead to quick and extensive deterioration of asphalt surfaces.
