摘　　要：采用双目型3D激光扫描仪对经过不同磨耗次数的水泥混凝土路面露石磨耗层表面三维信息进行采集,并基于三维纹理表征参数探讨了母岩骨料类型、骨料粒径和骨料出露姿态随磨耗作用的衰变规律。结果表明,母岩类型为玄武岩和辉绿岩,骨料最大粒径为13.2 mm和20 mm以及出露姿态为平躺出露和倾斜出露的骨料对于磨耗具有较高的抵抗能力。同时提出用于评价不同出露姿态的纹理衰变关键指标为:均方根高度Sq、陡峭度Sku和体积参数Vmc。In this paper,a binocular 3D laser scanner is used to collect the 3D information of the exposed stone wearing course surface after different wear times,and the decay law of the parent rock aggregate type,aggregate particle size and aggregate exposure attitude with wear is discussed based on the 3D texture characterization parameters.The results show that the aggregates parent rock types are basact and diabase,the maximum particle size of 13.2 and 20.0 mm,and exposure attitude of flat and inclined exposure have high resistance to abrasion.At the same time,the key indicators of texture decay used to evaluate different exposure attitudes are root mean square height Sq,steep degree Sku and volume parameter Vmc.
