| Abstract: | The reasons for quality defect existing during the paving of LSPM（Large Stone Porous Asphalt Mixture） for expressway in progress are analyzed. Construction technology and arrangement, including strengthening the control of specification of material and mixing and the adjustment of control parameters during paving and compacting, are taken to make sure the good performance and function of LSPM are fully played, which is good for the popularization of LSPM. |
