速度和构造深度对水泥混凝土路面摩擦系数的影响

Influence of Speed and Texture Depth on Skid Resistance of Pavement Surface

为了研究摩擦系数与速度、路面构造深度的关系,采用新型路面抗滑检测设备,对不同水泥混凝土路面的动态摩擦系数和构造深度进行了分析,研究结果表明,在路面构造深度较好的情况下,水泥混凝土路面摩擦系数随速度升高而降低.摩擦系数变化率随路面构造深度增大而增大.路面的抗滑性能与路面表面特征和行车速度有较大的关系,应该在路面的设计和施工养护中予以考虑.

In order to study the relationship between friction coefficient and texture depth of pavement surface,and the relationship between friction coefficient of pavement surface and vehicle speed,the paper analyses the dynamic friction coefficient and texture depth of different cement concrete pavement by use of advanced tester.The result shows that friction coefficient varies with speed,and the varying rate of friction coefficient is related to texture depth.Friction coefficient decreases quicker when texture de...
