Abstract

In this study, we reviewed the applicability of the existing Temperature-compensated deflection equation using a Representative temperature estimation method using existing research results, and improved and verified it to a domestically new temperature-compensated deflection equation that takes into account various asphalt thicknesses. In addition, based on the FWD test-data of porous asphalt pavement, we propose a analyzing process for the performance degradation of porous asphalt pavement, including a process of performing standard load and temperature correction on FWD data, and a conversion process of FWD Back-calculation elastic modulus to field dynamic elastic modulus. After proposing the process, a Excel program was developed for the evaluating the degradation of performance in the porous asphalt pavement using the concept of dynamic elastic modulus.
