Determination of Creep Compliance and Indirect Tensile Strength for the Mechanistic-Empirical Pavement Design Guide (MEPDG)

Abstract

This report provides details of the research, including data analyses and results, conducted into creep compliance and indirect tensile strength tests for use in the Mechanistic Empirical Pavement Design Guide (MEPDG). The study was conducted on field cores from the Idaho Transportation Department as part of an ongoing project at the University of Idaho. The data reported in this study were provided to University of Idaho researchers for use in the AASHTOWare Pavement ME thermal cracking database. By means of this database thermal cracking models in the AASHTOWare Pavement ME can be calibrated for the mixes used by the state of Idaho. Such local calibration will increase the reliability of these models for pavement design in Idaho.
