辽宁省货车车道沥青路面路表弯沉温度影响系数研究

Research on Influence Coefficient of Surface Deflection Temperature of Asphalt Pavement of Truck Lane in Liaoning Province

结合某货车车道试验段,根据不同温度下沥青路面弯沉实测值,回归出温度与弯沉的相关关系,进而得出实际弯沉温度影响系数,通过对比实测及按规范计算的温度影响系数,得出适用于辽宁省货车车道的路表弯沉温度影响系数的区域修正系数。

In combination with the test section of a truck lane,according to the actual measured values of asphalt pavement deflection under different temperatures,the correlation between temperature and deflection is regressed,so as to obtain the influence coefficient of actual deflection temperature.The regional correction coefficient of surface deflection temperature influence coefficient suitable for truck lane in Liaoning region is obtained by comparing the influence coefficient of measured temperature with that calculated according to the specification.
