Abstract:Aiming at the quality defect existing in the construction of the expressway for paving the large bituminous macadam,this article ascertains the types of defects.The causes are also discussed and studied,and corresponding countermeasures are made.By improving the construction skills and organizations of LSPM,paying attention to standards of raw materials,and controlling the mixing,spreading and pressing parameters,the advantages and excellent functions of LSPM are made use of thoroughly.Thus,the happening of quality defects is reduced and avoided,which is favorable to popularize LSPM.
Keywords:LSPM
