摘　　要：为解决沥青路面在传统测量方法中受到环境条件的限制和测量结果中纹理信息数据的丢失问题,实现科学、合理地评估沥青路面在服务期限内实时抗滑性能,提出基于倾斜摄影技术和定位技术,通过三维重构软件CC(Context Capture)和Matlab创建分析模块与数字化处理的实时识别系统,获取路面纹理参数平均构造深度(MTD)、沥青路面凸起构造体积占总构造体积之比(凹凸比),并与铺砂法测量的平均构造深度、摆式仪测量的摆值等传统测量方法相对比分析。结果表明,采用倾斜摄影技术获取的MTD与铺砂法获取的构造深度相关性R2=0.997 7,构造深度结合凹凸比反映的路面抗滑性能具有准确性和有效性,精度识别在路面纹理构造信息接近于0.01 mm,可作为路面抗滑性检测的新手段,为道路评价、管理监测和养护提供精确性、实时性的抗滑数据参考。In order to solve the problem of asphalt pavement being limited by environmental conditions in traditional measurement methods and the loss of texture information data in the measurement results, and to achieve scientific and reasonable evaluation of real-time anti-sliding performance of asphalt pavement during the service period, based on oblique photography technology and positioning technology, the analysis module and digital processing real-time recognition system created by the 3D reconstruction software CC(Context Capture) and Matlab were proposed. The average construction depth of texture parameters of the pavement-MTD, the ratio of the raised structure volume of asphalt pavement to the total structural volume-concave convex ratio were obtained. It was compared with the traditional measurement methods such as the structural depth measured by the sand-laying method and the pendulum value measured by the pendulum instrument. The results showed that the correlation R~2 between MTD obtained by oblique photography technology and the sand-laying method was 0.997 7, and the anti-sliding performance of the pavement reflected by the construction depth combined with the concave convex ratio had accuracy and effectiveness, so the accuracy recognition of the texture structure information on the pavement was close to 0.01 mm, which can be used as a new means for pavement sliding resistance detection, providing accurate and real-time anti-sliding data reference for road evaluation, management monitoring and maintenance.
