The California Department of Transportation (Caltrans) has funded the development of design models for flexible pavements and for overlays that have been incorporated in the software currently known as CalME. Under the direction of University of California Pavement Research Center (UCPRC) staff over a two-year period, personnel from the Washington State Department of Transportation (WSDOT), the Texas Department of Transportation (TxDOT), and the Minnesota Department of Transportation (MnDOT) participated in examining these models and identifying areas where they might be modified or enhanced.
This project was funded by State Pavement Technology Consortium (SPTC -- California, Minnesota, Texas, and Washington) through a pooled-fund study.
In-person training on CalME was provided by UCPRC at each of the participating state departments of transportation (DOTs). Case studies were conducted by UCPRC using data provided by the individual DOTs. Feedback was collected throughout the project and questionnaires were sent at its completion to collect final comments on CalME. This technical memorandum describes the researchers’ efforts, including details of the evaluation and data collection procedures, other activities undertaken, and the case study using CalME. The participating states found many CalME features helpful and might adopt a selected set of models or approaches in their respective efforts to implement Mechanistic-Empirical design.
