浅析SBS改性沥青混凝土路面施工工艺

Construction Technology of SBS Modified Asphalt Concrete Pavement

由于现代道路交通的“交通量大、轴载重、渠化严重”,因此,道路交通路面必须采用高性能沥青混凝土材料避免以上问题的发生。研究发现SBS等高分子聚合物来改性沥青中的应用,可以改善沥青路面的路用性能,增强路面抗裂、耐磨性能。因此,本文在全面阐述SBS改性沥青优点的同时,分析了SBS改性沥青混凝土路用性能,并结合具体案例探讨了SBS改性沥青混凝土路面施工工艺。

Due to the"large traffic volume,heavy axle load,and serious channelization"of modern road traffic,highperformance asphalt concrete materials must be used to avoid the above problems.The study found that the application of SBS and other high molecular polymers to modify asphalt can improve the road performance of asphalt pavement,and enhance the crack resistance and wear resistance of pavement.Therefore,in this paper,while fully elaborating the advantages of SBS modified asphalt,the road performance of SBS modified asphalt concrete is analyzed,and the construction technology of SBS modified asphalt concrete pavement is discussed in conjunction with specific cases.
