The paper points out the limits of current approaches to predict the evolution of skid resistance over time from the road surface texture. Simulation in laboratory of traffic-induced polishing shows that the friction coefficient measured on an asphalt concrete first increases, reaches a maximum then decreases. In the meantime, texture parameters evolve in a scattered way and do not reflect the friction evolution. Comparison of scanning electron photos at different polishing stages reveal cracking in the bitumen layer and the aggregates and fracture at late polishing stages. These findings prove that wear of road surfaces results from more complex processes than just a modification of the surface texture. Considering asphalt concretes as a coated system, with the bitumen deposited as a coating on the substrate composed of aggregates, a more systematic approach is derived to better understand the basic mechanisms. At the micro-scale, similarities in terms of debris formation allow...

对通过路面纹理交通预测轮胎/道路摩擦演变的方法提出质疑

本文指出了目前从路面纹理预测防滑阻力随时间演变的方法的局限性。在交通诱导抛光的实验室中进行的仿真表明，在沥青混凝土上测得的摩擦系数先增大，然后达到最大值，然后减小。同时，纹理参数以分散的方式发展，并且不反映摩擦的发展。在不同抛光阶段扫描电子照片的比较表明，沥青层破裂，聚集体破裂以及在抛光后期断裂。这些发现证明，道路表面的磨损不仅仅是复杂的表面纹理，而是更为复杂的过程造成的。将沥青混凝土视为涂层系统，将沥青作为涂层沉积在由骨料组成的基材上，派生了一个更系统的方法来更好地了解基本机制。在微观尺度上，碎屑形成方面的相似性使得...
