摘要
为准确评价排水沥青路面的抗滑性能,对摆式摩擦系数、动态旋转式摩擦系数、横向力系数、构造深度和刹车距离等评价指标进行了试验对比分析,优选适用于排水沥青路面的抗滑性能评价标准。结果表明:动态摩擦系数和刹车距离具有较好的关联性,动态摩擦系数和横向力系数能够较好地反映排水沥青路面抗滑性能。推荐动态摩擦系数(DF60)为抗滑性能的首选评价指标;横向摩擦系数(SFC50)和动态摩擦系数(DF60)为工程验收的主要指标。
To accurately evaluate the skidding performance of porous pavement,the paper analyzes the different evaluation indexes including tilting friction coefficient,dynamic rotary friction coefficient,sideway force coefficient,structural depth and braking distance. The evaluation index of skidding performance which more suitable for porous pavement is optimized. The results show that dynamic friction coefficient( DF60) and sideway force coefficient( SFC50) can preferably evaluate the skidding performance of porous pavement. And the dynamic friction coefficient( DF60) is the first choice among the evaluation indexes of skidding performance in porous pavement.
