Abstract: As part of the Caltrans Long Life Pavement Rehabilitation Strategies (LLPRS), a concrete pavement constructed with fast setting strength hydraulic cement concrete (FSHCC) and Portland cement concrete (PCC) blend was constructed on State Route 14 about 5 miles south of Palmdale, California. The test pavement was evaluated under Heavy Vehicle Simulator (HVS) testing beginning June 1999 and finishing December 2001. This report summarizes part of the testing program which was undertaken on three 70-m long test sections with a 200-mm thick FSHCC and the following design features: * Section 7 was constructed with plain joints (no dowels), relying on aggregate interlock for joint load transfer, with an asphalt concrete shoulder and a normal lane width of 3.66 m. * Section 9 was constructed with dowels and a concrete shoulder with tie bars and a normal lane width of 3.66 m. * Section 11 was constructed using a widened truck lane (4.26 m wide) and doweled joints with an asphalt concrete shoulder. The most significant observations are briefly discussed subsequently.
