路表纹理多尺度特性表征及演化行为研究综述

为了量化路表纹理的多尺度特征，厘清路表纹理的演化行为，概述了路表纹理尺度特征及其影响，总结了多尺度表征的数学理论方法，分析了表面纹理演化机理及磨光演化模型。结果表明：不同尺度的路表纹理影响着安全、环境、经济等方面。路表纹理在结构特性上具有统计几何、频谱及自仿相似特征。在路表纹理形成期，材料、级配及施工等决定了表面纹理水平，而在劣化期主要受到表面雨雪冰霜、沉积污染物以及荷载磨光等因素影响。解析胎-路接触应力是预测路表纹理磨光演化行为的有效途径。未来研究有必要研究纹理尺度之间的相关性、表面纹理与内部结构的映射关系、碳排放的量化关系以及接触状态理论力学等问题，为材料力学设计、快速检测评价及智能养护提供理论和应用支持。

Review on Multi-scale Characterization and Evolution of Pavement Texture

To characterize the multi-scale characteristics of pavement surface texture, and reveal the texture evolution mechanism, the multi-scale characterization and evolution analysis of surface texture were summarized. The scale ranges of surface texture and the influence of multi-scale features were introduced in this paper. The current detection technology and the mathematical characterization of pavement texture were generalized. Also, the various texture evolution mechanisms and mechanical polishing models were focused. The results show that the pavement texture on different scales affects safety, environment and economy, etc, respectively. Pavement texture possesses the structural characteristics of statistical geometry, spectrum and self-affine. During the formation period, the texture level is determined by the material, aggregate gradation and construction technology, while it is mainly affected by some factors, such as rain, snow, ice, frost, deposit sediment and traffic polishing in the deterioration period. The analysis of tire-road contact stress is an effective way to predict the polishing evolution of road surface texture. It is recommended to further study the correlation among the texture scales, the mapping relation between surface texture and internal structure, the model between road surface texture and carbon emission, and the contact mechanical theory. It will hopefully provide theoretical and practical support for the material design, rapid detection/evaluation, and intelligent maintenance.
