The value of an asphalt pavement is dictated by its performance, which is related to the level of distresses in the pavement. The two main pavement distresses are rutting and fatigue cracking. Rutting is a phenomenon that is exhibited through surface depression under the wheel path (Figure 1a). There are two types of rutting: asphalt rutting and subgrade rutting. Subgrade rutting is a structural problem and is not of interest in this paper. Asphalt rutting is directly related to material properties of the asphalt mixture at the surface of the pavement and typically results from poor materials selection, deficient compaction, sub-optimal mix design, among other constructability problems. Rutting typically occurs at high temperatures and low loading frequency (slow vehicle speed). On the other hand, fatigue cracking consists is manifested through the formation of a series of interconnected cracks caused by failure of the asphalt pavement at moderate temperatures under repetitive traffic loading (Figure 1b).
