摘　　要：根据落锤式弯沉仪 (FWD)实测的弯沉盆 ,采用同伦方法反算沥青路面结构层的模量 ,分析沥青面层反算模量与温度的统计关系 ,并建立反算模量的温度修正公式。The Structure layer moduli of asphalt pavements are back calculated with the homotopy method according to the deflection basins measured by Falling Weight Deflectometer (FWD). The regression models for relating the back calculation moduli of asphalt surface to the temperatures are analyzed. So, the equations for temperature adjustments of back calculation moduli are developed.
