• Description:
  In this report, the author evaluates the effect of aggregate base density and permeability on in-situ moisture content. He also assesses the effectiveness of asphalt treated permeable base (ATPB) courses and makes recommendations for future testing. The report characterizes the aggregate base material that is used for California Department of Transportation (Caltrans) Accelerated Pavement Testing (APT) Goal 5. It summarizes laboratory and field test evaluations of aggregate base material that was used in the construction of the Heavy Vehicle Simulator (HVS) test sections at the University of California's Richmond Field Station. The report recommends the elimination of the ATPB layer and increasing the Caltrans specification for compaction. The recommendations are intended to reduce permeability, increase strength and stiffness, and increase asphalt concrete fatigue life thus leading to pavements with lower maintenance costs and longer life.
