沥青混合料的弹性模量取决于温度。即使在同一点进行FWD测试，挠度也会随温度而变化。因此，需要通过反算对弯沉和弹性模量进行温度修正，以得到相同温度条件下的路面性能。本文根据FWD试验场的实测数据，开发了集温度预测和弯沉修正于一体的沥青层温度修正系统。毕竟，该系统也被发现是充分适用于FWD数据在现场。
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.
