沥青路面下封层材料 结构 力学性能的研究

Research on Sealing Material Structure and Mechanical Performance

针对高速公路沥青路面下封层应用现状 ,采用几种试验方法 ,对乳化沥青材料、下封层结构及力学性能进行了室内试验研究。在此基础上分别在江苏沿江高速公路及连徐高速公路铺筑了乳化沥青下封层、改性乳化沥青下封层、改性热沥青下封层、稀浆封层以及单层式、双层式下封层试验路 ,并对试验路进行了性能检测 。

According to application practice of asphalt pavement sealing, materials,structure and mechanical performance of the asphalt pavement sealing were mainly studied by using the new experiment methods. Based on this research, many test roads were built, such as Yanjiang expressway,Lianxu expressway. In these roads, modified emulsive asphalt sealing,modified asphalt sealing ,sulrried sealing and single,double structure sealing were fully studied. Based on these research, proper materials and sealing structure were proposed.
