在内蒙古自治区赤峰-通辽段高速公路沥青路面施工中,以SBS改性乳化沥青代替普通沥青作透层、粘层,其防水、粘结、抗剪能力等方面都优于普通沥青,能有效地减少路面损坏,提高路面使用寿命,其推广应用将为公路行业产生很大的经济效益。文章主要阐述了SBS改性乳化沥青在沥青路面透层的应用。

Application of SBS emulsified modified emulsified asphalt to the construction of Chifeng to Tongliao Expressway

The SBS modified emulsified asphalt,which was used in the construction of Chifeng to Tongliao Expressway in Inner Mongolia,taking place of the normal asphalt as prime coat,and cohesion layers being better than the normal asphalt,in waterproofing,bonding and shear resistance,etc.,can effectively reduce the pavement damage and extend the service life of pavement.The application of the modified emulsified asphalt to the highway construction would bring about major economic benefit.This article describes the application of SBS modified emulsified asphalt to the prime coat of asphalt pavement.
