摘　　要：为研究沥青路面宏、微观纹理特性与抗滑性能的相关关系,选择营运中的沥青道路作为研究对象,采用激光纹理扫描小车进行沥青路面宏、微观纹理的像素值测定,使用Matlab软件重构了沥青路面的三维数据模型.同时,利用摆式摩擦测定仪测量沥青路面摆值.最后,计算沥青混凝土路面纹理构造参数并分析沥青路面构造参数和路面抗滑性能指标间的相关性.研究表明:相对于路面轮廓无规则方向,路面轮廓竖直方向的评价指标与抗滑指标的相关性更强;纹理指标中,平均断面深度MPD与路面轮廓算术平均偏差Ra与路面抗滑性能具有较好的正相关关系,其中路面轮廓算术平均偏差Ra与摆值的相关性大于平均断面深度MPD与摆值的相关性.In order to study the correlation between macro and micro texture characteristics of asphalt pavement and skid resistance,selects the asphalt pavement in operation on campus as the research object,uses a laser texture scanning car to measure the pixel value of macro and micro textures of asphalt pavement,and uses Matlab software to reconstruct the three-dimensional data model of asphalt pavement.At the same time,the pendulum friction tester is used to measure the pendulum value of asphalt pavement.Finally,calculate asphalt concrete pavement texture parameters and analyze correlation between asphalt pavement texture parameters and pavement skid resistance.The research shows that the correlation between the evaluation index of the vertical direction of the pavement profile and the skid resistance index is stronger than that of the irregular direction of the pavement profile.Among the texture indicators,the arithmetic mean deviation Ra of the average section depth MPD and the pavement profile has a good positive correlation with the skid resistance performance of the pavement,in which the correlation between the arithmetic mean deviation Ra of the pavement profile and the swing value is greater than the correlation between the average section depth MPD and the swing value.
