Methodology and Calibration of Fatigue Transfer Functions for Mechanistic Empirical Flexible Pavement Design

Abstract

An accurate fatigue transfer function is the critical link in M-E flexible pavement design. The model relates the conditions of the pavement structure to the expected performance or life of the pavement. The conclusions of this research, including the developed methodology and transfer functions, are presented below. Following the conclusions, a few recommendations on testing procedure and data collection for future testing cycles are presented. Further, this component of M-E design is probably the most deficient; thus, it warrants further attention and improvements. The recommendations based on this study for additional improvements and research are also given.
