WEEKEND RECONSTRUCTION--URBAN CONCRETE PAVEMENT ON INTERSTATE 10

In 1998, Caltrans launched its long-life pavement rehabilitation strategies program to rebuild 3,000 lane-km of the California state highway network over 10 years. Caltrans needed to determine which pavement designs, materials, traffic management, and reconstruction strategies were most suitable to help achieve their objectives for long-life pavement and minimal traffic delay. Caltrans decided to conduct a 55-hour weekend construction closure on Interstate 10 in Pomona to determine how many lane-km of existing PCC slab could be replaced using fast-setting hydraulic cement concrete capable of very early strength gain. The Innovative Pavement Research Foundation engaged the services of researchers at the University of California at Berkeley to document this project. This case study provides an overview of this research effort and its findings.
