Abstract

To valuate the domestic asphalt pavement, it is necessary to consider the temperature of the four seasons with a large temperature change range. Therefore, the FWD deflection value tested at the temperature of each season must be corrected according to the reference temperature. In this study, a temperature correction formula of FWD deflections ware developed based on the long-term monitored section without performance change under domestic climatic conditions. As a result of applying the developed formula to FWD field data in the domestic temperature range, it was found that it can be appropriately used in Korea, where the mean value and standard deviation value has less fluctuation than the other existing temperature correction formula.
