A street construction program using deep-lift Full-Depth Asphaltic concrete placed on the natural subgrade is briefly reviewed, and the Benkelman Beam rebound deflection tests to evaluate the structural adequacy of the pavements are described. The recorded rebound deflections were used to determine the representative rebound deflections. This value is the mean of the rebound deflection plus two standard deviations, multiplied by the temperature adjustment factor for reference to 70 F. and if necessary, a critical period adjustment factor. Data are presented (tabulated) for pavement evaluation using temperature adjustment factors(according to the procedure outlined in the Asphalt Institute Manual). The results of the Benkelman Beam rebound deflection tests lead to the conclusion that deep lift full-depth asphalt pavement constructed on the natural subgrade in Woodbridge Township has an expected life of 45 to 50 years based on a 4 percent per year growth rate.
