Skid resistance is essential for road user safety and depends directly on the texture of the pavement. This texture is related to the surface texture of the aggregates. During its lifetime, the texture of the pavement evolves under the wear induced by road traffic. This phenomenon is called polishing. This paper presents a multiscale method based on the continuous wavelet decomposition of pavement texture to follow the evolution of the texture of aggregates during polishing at different scales. Several indicators are proposed to assess texture evolution and to correlate with friction evolution. The relevance of these parameters is assessed on samples composed of aggregates, which surface is characterized through laboratory experiments.

抛光过程中路面纹理的多尺度分析

防滑性能对于道路使用者的安全至关重要，直接取决于路面的质地。该纹理与聚集体的表面纹理有关。在路面的使用寿命中，路面的质地会在道路交通引起的磨损下发展。这种现象称为抛光。本文提出一种基于路面纹理连续小波分解的多尺度方法，以跟踪不同尺度抛光过程中骨料纹理的演变。提出了几种指标来评估纹理演变并与摩擦演变相关。这些参数的相关性是在由骨料组成的样品上评估的，其表面通过实验室实验进行了表征。
