半刚性基层沥青路面高温修正系数研究

Research on temperature correction coefficient of asphalt pavement with semi-rigid base

基于弹性层状理论,运用apbi计算程序,考虑高温对沥青混合料模量的影响,采用路表弯沉值为指标,基于大量计算数据分析温度对半刚性基层沥青路面轴载换算的影响,并结合江苏地区的具体情况,给出了高温修正系数β的建议值,约为1.73。

Based on the layer-elastic theory,apbi software is used to calculate the temperature correction coefficient of asphalt pavement with semi-rigid base. While the influence of temperature on the modulus of the pavement has been taken into consideration,using the deflection value to compare different axle-load exchange outcome under different temperature. The recommended temperature correction coefficient of asphalt pavement with semi-rigid base in Jiangsu province is about 1. 73.
