摘　　要：为防止沥青加铺层产生车辙病害和反射裂缝,某高速公路长大纵坡段水泥路面改造第一次采用了改性沥青+高模量+聚脂纤维沥青混合料作为沥青面层,文章对其配合比设计和施工技术进行详细的介绍,实践证明该沥青混合料设计合理,可供类似长大纵坡路段路面改造工程参考。In order to prevent rutting disease and reflection crack in asphalt overlay, the mixture with modified asphalt, high modulus and polyester fiber is firstly used as pavement in a cement pavement reconstruction project with long and large longi- tudinal slope. This paper introduces its mix ratio design and construction technology in detail. The mixture design is proved to be reasonable by practice and could be could be taken as reference for similar pavement reconstruction project.
