沥青路面的抗滑性能决定了路面的行驶速度与舒适程度,路面抗滑性能是指车辆轮胎受到制动时沿表面滑移所产生的力。通常抗滑性能被看作是路面的表面特性,并用轮胎与路面间的摩阻系数来表示。一般用摩擦系数表征抗滑性能,摩擦系数小,抗滑能力就低,容易引发交通事故。表面特性包括路表面细构造和粗构造,影响路面抗滑性能的因素有路面表面特性、路面潮湿程度和行车速度。文中结合作者自身的实践经验对沥青路面的抗滑性能检测技术进行了深入的探讨,以供广大读者参考借鉴。
The anti-skid performance of asphalt pavement determines the running speed and comfort level of the pavement. The anti-skid performance of the pavement refers to the force generated when the tire of the vehicle slides along the surface when the tire is braked. Skid resistance is usually seen as the surface characteristics of the road surface, and tire friction coefficient between the road to represent. Commonly used friction coefficient characterization of anti-skid performance, small friction coefficient, low skid resistance, easily lead to traffic accidents. The surface characteristics include fine structure and rough structure of the road surface. The factors affecting the anti-sliding performance of the road surface are the surface characteristics of the pavement, the degree of pavement moisture and the driving speed. In this paper, with the author’s own practical experience on asphalt pavement anti-skid performance testing technology for in-depth discussion for the general reference for readers.
