Abstract
Elastic modulus of asphalt mixture depends on temperature. Even though FWD test is carried out at the same point, deflection varies with temperature. Therefore, the temperature correction of deflection and elastic modulus by backcalculation is necessary to get the pavement behavior under the same temperature condition. In this study, temperature correction system with both prediction of temperature and correction of deflection in asphalt layers is developed based on the data in the test yard for FWD. After all, this system is found to be also sufficiently applicable to FWD data in site.
