Implementation of Concrete Overlay Evaluation and Design

The primary tasks in this implementation project are to train TxDOT Staff (1) to evaluate existing Portland Cement Concrete (PCC) pavements and develop appropriate optimum overlay strategies and (2) to conduct early-age performance evaluations of PCC overlays. This implementation project also includes the development of training materials and other documents that will be used to modify the PCC overlay portion of TxDOT Pavement Manual. TxDOT has many miles of concrete pavement that have already passed or are approaching the end of their design lives, which will require some form of rehabilitation in the near future. The PCC overlay design program developed under previous research project #0-6910 represents significant improvements over existing PCC overlay design programs, primarily because the new program is based on the “mechanistic” condition of the existing pavement, not “visual condition” of the pavement. The findings from this implementation project will help TxDOT deploy cost-effective pavement rehabilitation programs.
