旧水泥路面沥青加铺层抗剪切疲劳分析

The anti-shearing fatigue analysis of old cement pavement asphalt additional layer

基于剪切疲劳损伤等效原则的标准轴载换算,通过直道试验数据回归得到剪切疲劳方程,对比分析旧水泥混凝土路面加铺GSOG-20沥青材料层与AC-20沥青材料层抗剪切疲劳的效果,选出了优选方案。

Based on the standard axial conversion of shearing fatigue damaging equivalence principle, it gets the shearing fatigue equation through chute experimental data regression, compares and analyses the effects of old cement concrete pavement adding GSOG-20 asphalt layer and AC-20 asphalt layer to anti-shearing fatigue, and selects the optimum program.
