Abstract:
The development process included a number of phases, which are described in the report. Included in this report are the following: 1) a state-of-knowledge review for fatigue response of asphalt aggregate mixes, 2) a description of a pilot test program and its results, 3) a description of an expanded test program using the equipment and methodology selected in the pilot test program, and 4) a description of a mix analysis and design system, which can be used to mitigate fatigue cracking.
