Abstract

For flexible pavement Overlay design processes, the new Mechanistic-Empirical Pavement Design approach relies
heavily on the material stiffness, back calculated from the deflection measurements taken from existing pavements. These
measurements are typically made using Falling Weight Deflectometer (FWD). In order to provide high quality and consistent
material stiffness data for the Mechanistic-Empirical Pavement Design the deflection results obtained at radial distance in
between 0 and 1800 mm through geophone in FWD is highly useful. This research sought to examine the remaining life in
FWD testing, analysis procedures and its research findings at national and international scenario. The deflection value
obtained from FWD load application is directly used to estimate the structural and function condition of pavement is
highlighted. Back calculation methods, correction to seasonal variations and calibration of FWD are not reviewed.
