冷再生旧沥青混凝土路面基层的质量控制

Quality Control of Cool Regeneration of Old Asphalt Concrete Pavement Base Layer

为了保证冷再生旧沥青混凝土路面基层的质量,应对混合料进行重型击实试验,确定最佳用水量和最大干密度,并选用终凝时间较长的水泥品种;在施工过程中,应确定合理的施工段落长度并保持施工的连续性,同时准确控制水泥的添加剂量和施工工艺。

In order to ensure the quality of cool regeneration of old asphalt concrete pavement base layer, heavy compact test of compound material should be carried out to define best water usage and maximum dry density, and to use the cement that is of long time of final coagulation. It is necessary to define reasonable construction length to ensure continuous construction, and correctly control cement agent and construction technique.
