Top-Down Fatigue Cracking of Hot-Mix Asphalt Layers - Phase I

The objectives of this research are to (1) identify the mechanisms that govern the initiation and propagation of top-down fatigue cracking in HMA layers, (2) identify or develop method(s) of laboratory testing HMA mixtures for determining susceptibility of the HMA surface layer to this cracking, (3) determine the significant factors associated with the occurrence of top-down fatigue cracking, and (4) identify promising models for predicting the initiation and propagation of top-down cracking.
