摘要
目前,高速公路罩面层下防水层大多采用SBS改性沥青。该文提出用天然岩沥青改性沥青作防水层,并对其进行了室内试验和试验路观测。对天然岩沥青改性沥青防水层与SBS改性沥青防水层进行了比较,指出天然岩沥青改性沥青防水层适合夏季气温较高的地区,对其进行大量推广可以产生较大的经济效益。
SBS improved asphalt is used as waterproof layer under road surface of expressway at present.This paper points out that natural rock improved asphalt can be used as waterproof layer,and laboratory test and site inspection are carried out.Comparison between natural rocks improved asphalt and SBS improved asphalt is done.It is found that natural rock improved asphalt waterproof is suitable for the area having high temperature in summer,and may bring great economic benefits if popularization.
