提出在旧沥青混凝土路面铺设两油一布铺撒碎石矿料进行综合表面处治的方法,以提高旧沥青混凝土路面的防滑、防水、耐磨等性能。室内对综合表面处治所用原材料进行研究,提出了质量控制指标,并根据其结构特点确定出单位面积的沥青最佳用量和矿料最佳用量。利用沥青混凝土路面结构层抗剪试验机对成型路面处治进行抗摩擦性能的测试。通过试验路进一步提出了旧沥青混凝土路面表面处治的施工工艺及质量控制参数。
Proposed in the old asphalt pavement laying two oil a cloth paving stone aggregate method of comprehensive surface treatment to improve the old asphalt concrete pavement slip, water, wear and other properties. Indoor comprehensive study of the surface treatment of raw materials used to put forward the quality control indicators, and according to its structural characteristics to determine the best per unit area of asphalt and mineral dosage the best dosage. The asphalt pavement structure layer shear testing machine is used to test the anti-friction performance of the molded pavement. Through the test road, the construction technology and quality control parameters of the surface treatment of the old asphalt concrete pavement are further proposed.
