沥青混凝土路面防水剂路用性能试验研究

目前,沥青混凝土路面在我国高速公路建设中得到了广泛的推广和应用,而水损害是沥青混凝土路面早期破坏的主要原因之一。文章通过对沥青混凝土路面防水剂防水性能进行对比试验,表明沥青混凝土防水剂可以有效的封堵沥青混凝土内部孔隙,防止水分进入混凝土内部,可以起到防水路面水损害的作用,同时指出沥青混凝土防水剂对路面抗滑性能存在负面影响等应注意的问题。

Experimental Research on the Function of Waterproof Agent for the Asphalt Concrete Pavement

At present,asphalt concrete pavement is widely used and popularized in the expressway in China. The water-in- duced damage is one of the main reasons for early destroy of asphalt concrete pave- ment.Through a comparison test on the performance of waterproof agents for as- phalt concrete pavement,the article con- cludes that the waterproof agent used in bituminous concrete can effectively seal and block the internal hole of bituminous concrete,and keep the humidity from ente- ring the inner part of concrete. As a re- sult,it plays a role in preventing water damage on the road surface. The article al- so points out some negative influences on the skid resistance of the pavement,which should be paid attention to in the applica- tion.
