Long-Life Asphalt Pavement (Perpetual Pavement)


A joint Caltrans-construction industry-Univeristy of California effort

In 2003, the California Department of Transportation (Caltrans),  the asphalt pavement industry and the University of California Pavement Research Center (UCPRC) launched a collaborative effort to test long-life pavement strategies on a rehabilitation project on the 710 Freeway in Southern California, and so far the project is performing as expected. Caltrans and industry are working together with the goal of developing additional long-life pavement projects elsewhere in California. This webpage has been established to assemble pertinent information related to the effort.
