Abstract:

In describing the effect of coarse aggregate type on the performance of CRCP, this report documents the design, construction, and monitoring of 32 test sections in Houston, Texas. Constructed to evaluate the performance of pavements built in accordance with the CRCP-89(B) design detail recent developed by TxDOT, these test sections were monitored to determine the field performance of CRCP 2 years after construction, looking in particular at crack spacings and crack width. Then, using the observed performance of the different coarse aggregates, the study team evaluated the recently developed CRCP-89(B) design detail. Finally, using the CRCP-7 computer program, the predicted performance was compared with the measured performance of the CRCP test sections. Based on this comparison, a new model to be used with the CRCP-7 program - one capable of predicting crack widths - was developed.
