CalME: Caltrans Mechanistic-Empirical Tool

CalME

Version:3.DD001.3August 2020

This tool was developed by the University of California Pavement Research Center (UCPRC) for the California Department of Transportation (Caltrans).

CalME is a software program developed by Caltrans/UCPRC using the Mechanistic-Empirical (ME) methodologies for analyzing and designing the performance of flexible pavements. CalME uses an "incremental recursive" (I-R) approach that models the entire damage process, not just the initial condition after construction and the final failure condition. Instead, CalME simulates the pavement performance starting from the initial undamaged pavement stress, strain, and deformation responses to temperature and load to the end failure state. CalME has been calibrated using data from Caltrans pavement management system.
