University of California Pavement Research Center

This report provides a summary of the Phase II portion (1994-2000) of the Caltrans Accelerated Pavement Testing (CAL/APT) Program. This research and development activity is a joint effort between Caltrans (California Department of Transportation), the University of California at Berkeley (UCB), the Division of Roads and Transport Technology of the Council of Scientific and Industrial Research (CSIR) of the Republic of South Africa, and Dynatest Consulting, Inc., of Ventura, California. The program utilizes two Heavy Vehicle Simulators (HVS) developed in South Africa. One of the HVS units is used to test full-scale pavements in a controlled environment at the UCB Pavement Research Center, located at the University of California Berkeley Richmond Field Station, while the other is utilized for testing in-service pavements and is currently in operation on State Route 14 near Palmdale, California. An extensive laboratory testing program involving the laboratories of both UCB and Caltrans complements the full-scale accelerated testing.
