Abstract: In Rancho Palos Verdes, Calif. a 4,300 ft. long test installation of the Contained Rock Asphalt Mat (CRAM) Pavement System is expected to have a 50 year life. It cost a third less than the estimate for a comparable conventional pavement because less materials are used to their maximum potential, efficiently distributing the stresses and strains imposed by wheel loads. The CRAM pavement is palced in four layers. A modified dense graded asphalt concrete layer is spread over a conventionally prepared subgrade, then a layer of open graded aggregate, a dense graded aggregate and, finally, a dense graded asphalt wearing surface.
