New Measurement Method of Concrete Pavement Surface Macro-Texture

Article Preview

Surface macro-texture in rigid pavements plays an important role in providing safety (providing skid reswastant surfaces) for the traveling public. In general, macro-texture of cement concrete pavements had been measured through sand patch method in China. With the development of measurement technique, some quick methods were applied, such as laser cross-section instrument. But it was unsuitable for the grooving concrete pavement because of its restrictions on measurement principle. So measurement of concrete pavement surface macro-texture based on 3-D optical dense point clouds was introduced in this paper. First, 3-D coordinates of the pavement surface were obtained by the 3-D optical measurement system, then 3-D texture model would be rebuilt with self-programming softwwere, at last the Mean Texture Depth (MTD) of surface could be calculated and compwered with sand patch method. The article studies brooming, grooving and exposed-aggregate cement concrete pavements, and make a correlation analyswas between MTD values of these two methods. The results indicated that they had good correlation, and the measurement technique based on 3-D optical dense point clouds could be used to evaluate cement concrete pavement surface macro-texture quickly
