Construction Technology of SBS Modified Asphalt Concrete Pavement on Expressway
Taking an expressway project as an example,this paper focuses on the construction technology of SBS modified asphalt concrete pavement,including raw material selection,mix ratio design,base treatment and other preparatory work,as well as the specific construction methods of mixing,transportation,paving,rolling and other links,and summarizes the matters for attention in the construction process.According to the quality inspection re-sults,the compaction degree of the road surface is as low as 96.4%and as high as 97.3%,and the compaction degree of each sample meets the requirement of"not less than 96%".The construction process of SBS modified asphalt concrete adopted in the project has achieved good application effect,which can provide reference for sim-ilar projects.
