摘要
用旋转压实剪切实验机 (GTM)设计方法设计的沥青混合料和粗密级配沥青混合料与一般沥青混合料相比 ,其压实要求高 ,压实难度大。压实是成功铺筑重载交通沥青混合料的关键因素。从适合的压实限制、压实空间(层厚与集料粒径大小关系 )、压实温度和压实作用等几个方面探讨了以防止车辙为主的重载交通沥青混合料的压实特性。
Heavy-duty asphalt mixtures include asphalt mixtures designed by gyratory testing machine(GTM) and coarse gradation mixtures. They are different from ordinary asphalt mixtures due to that the compaction density is higher and it is more difficult to compact. To pave pavement successfully, compaction is a crucial factor for heavy-duty asphalt mixtures. According to confinement, space. (the ratio of paving thickness and maximum nominal aggregate size), temperature and effort of the sutable compaction, the compaction properties of heavy-duty asphalt mixtures are discussed on the basis of preventing rutting.
