PACCAR FULL-SCALE PAVEMENT TESTS

An asphalt concrete section on a test track in the PACCAR Technical Center in Mount Vernon, Washington, was instrumented with strain gauges at the surface and in pavement cores, and tested using a Falling Weight Deflectometer (FWD) as well as trucks at different speeds and tire pressures. This report presents results from the analysis of the field tests using SAPSI, a computer program for the dynamic analysis of asphalt concrete pavements by the linear visco-elastic layer theory and the finite element method. The report also investigates the accuracy of SAPSI and includes some numerical criteria to be used when running the program.
