TRB’s National Cooperative Highway Research Program (NCHRP) Report 602: Calibration and Validation of the Enhanced Integrated Climatic Model for Pavement Design explores the evaluation, calibration, and validation of the Enhanced Integrated Climatic Model (EICM) incorporated in the original Version 0.7 (July 2004 release) of the Mechanistic-Empirical Pavement Design Guide (MEPDG) software with measured materials data from the Long-Term Pavement Performance Seasonal Monitoring Program (LTPP SMP) pavement sections. In addition, the report examines subsequent changes made to the EICM designed to improve its prediction of moisture equilibrium for granular bases.
NCHRP Report 602 is an abridgement of the contractor’s final report for Part II of NCHRP 9-23. The full text of the Part II final report and its six appendixes are available online.
