摘　　要：离析是路用集料施工分布不均匀性的综合表现,是引发沥青路面早期损坏的主要原因之一。通过对离析现象及成因、危害的讨论分析,提出了施工中防治离析的措施和一旦形成后的补救方法。离析完工后无法补救只能预防,采用正确的操作方法和通过加强对施工过程的科学管理与控制,是减少离析的关键。The segregation is comprehensive expression of non-uniform distribution in pavement aggregate construction. It is one ot the main reasons causing early damage of asphalt pavement. The prevention measures for segregation and the method of solution are put forward about discussing and analyzing the reason and harmfulness of the segregation phenomenon. The segregation ean be prevented for being not solution after construction completion. The key to the question is reducing the segregation by means of tightening up the scientifie management and control in the eonstruetion.
