| 摘 要： | 采用裂缝率、车辙、横向力系数和功能性破损率四个指标衡量沥青路面是否达到预防性养护标准。结合选取的锦阜、锦朝高速公路代表性路段检测数据分析评价,负指数函数y=a.e-bx能够很好地表征路面单值指标性能变化规律。通过分析预测,得到了锦阜、锦朝高速公路最佳的预防性养护年限。

| Abstract: | The percentage of crackings,rutting,transverse force coefficients and functional damage percentage are used to evaluate whether asphalt pavement can get to the preventative maintenance standards.Combined with the data tested from the representative sections on the Jin-Fu Expressway and Jin-Chao Expressway,the negative exponential function can characterize the performance change rule of pavement single value index.The optimal preventative maintenance lives of Jjin-Fu Expressway and Jin-Chao Expressway can be... |
