改性稀浆封层技术

Modified Slurry Sealing Technology

适应高等级公路路面维修养护的需要,改性稀浆封层技术在国际上得到迅速发展,即使用改性的乳化沥青与相适应的施工机械摊铺稀浆封层。铺筑这种改性稀浆封层可以缩短施工时封闭交通的时间,提高路面封层的耐磨、抗滑、耐候及韧性等技术性能,从而使稀浆封层技术得到新的发展。本文就这项技术的发展与其技术要求做扼要介绍。

To meet the needs of high grade road pavement maintenance,modified slurry sealing technology has been developing repidly in manycountries by using of modified emulsion bi tumen and efficient slurry sealingmachinery, which not only cut down working time with less influence ontraffic, but also improve the performance of wearing capacity, skid resis-tance, weather resistance sealing ductility. This paper outlines the develop-ment of the technology and technical requirements.
