Abstract
A simple dynamic analysis procedure for the falling weight deflectometer (FWD) test on airfield asphalt concrete pavements is presented. Several nondestructive tests were performed along a pavement using DynatestTM FWD equipment. The time histories of the surface deflections due to the dynamic load were recorded by several receivers. The asphalt concrete layer was assumed to be viscoelastic (Maxwell model), and the others were elastic. This assumption was verified by the hysteretic loop method. The viscoelastic concepts were employed to explain the time-delayed response. The dynamic properties (complex modulus and complex compliance) of the asphalt concrete layer and the material constants for the Maxwell model (elastic and viscous constant) were backcalculated based upon the test results.
