Refined Limiting Strain Criteria and Approximate Ranges of Maximum Thicknesses for Designing Long-Life Asphalt Pavements

This study focuses on pavement design thresholds for thickness to improve the cost effectiveness of perpetual pavements. Perpetual pavements are those pavements designed to address specific pavement distress including bottom-up fatigue cracking and subgrade rutting. A literature review was conducted and the field performance of pavement sections at the National Center for Asphalt Technology (NCAT) Pavement Test Track was analyzed. Recommendations for limiting cumulative strain distribution, fatigue ratios, and maximum asphalt concrete (AC) thickness are given.
