摘要

The objectives of this research study are to: Determine the asphalt mix properties (i.e. percent aggregate, sand and fine, aggregate angularity, binder type and content, and percent air content) that affect pavement rutting and fatigue cracking; Model the rut and fatigue cracks as functions of the asphalt mix properties, traffic load and volume, and the pavement cross-section; Recommend changes in the existing asphalt mix design, and construction practices to decrease rut and fatigue cracking potentials; and Develop an accurate, user-friendly, mechanistic computer program for the backcalculation of layer moduli.
