Cracking in asphalt concrete (AC)-surfaced pavements is a phenomenon that pavement design and maintenance engineers have had to contend with for years. It is one of two principal considerations (fatigue cracking and rutting) in the pavement design process, and it is the primary mode of deterioration in AC pavements. Cracks are inevitable, and
12 years after placement of the asphalt, depends on the severity of the climate region with respect to age-related cracking, the asphalt construction compaction, and the type of asphalt binder. More severe climates are those with hotter summers that accelerate aging and/or colder winters that result in more contraction of the asphalt.
