Study On Design And Application Of Asphalt-treated Permeable Base

Based on the construction of Jingdezhen-Wuyuan-Huangshan(Changshan) expressway in Jiangxi province, the paper argues the relationship between gradation and performance of asphalt-treated permeable base(ATPB) mixture, and the design method of ATPB mixture through theory analysis and application study; the paper analyzes the mechanics characteristics of the pavement structure containing ATPB, putting forward the mechanical performance requirements for ATPB. It also suggests the computation method and index for drainage performance requirements of ATPB mixture based on the weather condition. The void requirements scope of skeleton void asphalt mixture is given through analyzing relative literature.The paper also argues the application and construction technique of ATPB mixture. It summaries the application situation and technical requirement of ATPB mixture, analyzes the key technique in ATPB mixture and tests the construction application effect.
