小半径曲线路段沥青路面抗滑性能评价

Evaluation of Skid Resistance of Asphalt Pavement in Small Radius Curve Sections

路面抗滑能力是影响道路行车安全性的重要因素,特别是对小半径曲线路段沥青路面更为重要。通过对某高速公路小半径曲线路段沥青路面构造深度、横向力系数指标进行评价,提出了适合小半径曲线的横向力系数检测速率,得出了小半径曲线路段抗滑性能评价采用横向力系数指标更为合理。

Pavement skid resistance is an important factor that affects road traffic safety,especially for asphalt pavement with small radius curve sections.By evaluating the indexes of asphalt pavement texture depth and lateral force coefficient of a small radius curve section of a highway,this paper proposes a lateral force coefficient detection rate suitable for small radius curves and points out that it is more reasonable to use the lateral force coefficient index for the evaluation of the skid resistence of the small radius curve section.
