The pavement at research park called Research Parkway and Discovery Drive was found Deteriorated within two years of the construction. The need to evaluate the extent of the damage and the estimate of remaining life of pavement initiate the research study. The analysis presented in this report is based on the measurements of the surface deflections and the layered elastic theory. The life expectancy of the pavement can be estimated by the amount of pavement deflection developed within the pavement system. The parameters used in the analysis are the applied load, material of the pavement components and environmental effects. Trial and error method is used to estimate the in-situ moduli of the base course and the subbase course to best fit in the deflection basin. The modulus of the asphaltic concrete layer is determined from the falling weight deflectometer. The deflections were measured by the Benkelman Beam equipment and falling weight deflectometer for comparison. The analysis is done by using the CHEVRON computer program. The results of the analysis suggest that the asphaltic concrete layer may be the weaker layer and the probable cause of the early pavement deterioration.
