摘　　要：介绍了沥青路面形貌对路面使用性能的影响,分析了微观形貌对路面抗滑性能影响原理,并分别对沥青路面微观形貌信息各种采集方法、微观形貌特征统计参数、图像处理技术与分形等在微观形貌特征描述中的应用、基于沥青路面微观形貌特征的摩擦系数预测与评价、沥青路面宏观纹理对路面水膜深度的影响等研究现状进行概述,建议开展沥青路面微观形貌图像三维恢复、沥青路面微观形貌特征分形描述、运用人工智能分析的方法对路面摩擦系数预测与评价等研究,并在沥青路面水流生成影响因素分析的基础上,开展路面水流过程建模与仿真方法研究。The influence of asphalt pavement on pavement performance was introduced. The principle of the microscopic profile＇s influence on road surface skid resistance performance was analyzed. Many questions were introduced including various collecting method of asphalt pavement microscopic profile information, statistical parameter of the microscopic profile character, application of image processing technology and fracture to character description of the microscopic profile, friction coefficient forecast and evaluation based on asphalt pavement microscopic profile character, and influence of asphalt pavement macro-texture on water film. It was suggested that the research on pavement surface microscopic profile image three-dimenslonal restoration and fractal description, and the application of artificial intelligence analysis method to forecasting and appraising the asphalt pavement friction coefficient should be carried out, and that pavement surface water flow process modeling and simulation based on the water film influence factor analysis should also be carried out.
