TxDOT has the most mileage of continuously reinforced concrete pavement (CRCP) in the United States. Many miles of this pavement are quite old, still serving the states transportation needs well beyond their intended design lives. Meanwhile, some sections of CRCP experience premature distresses, requiring repairs and rehabilitations. It is important to understand what makes CRCP perform well, and what could cause distresses in CRCP. One objective of this study was to evaluate the overall performance of CRCP in Texas, along with identifying general characteristics of well-performing and poorly-performing CRCP. To improve the accuracy of pavement design procedures, national efforts were made within the last 10 years, which resulted in the development of a Mechanistic-Empirical Pavement Design Guide (MEPDG). The other objective of this study was to collect information needed to calibrate MEPDG to Texas conditions.
