磨耗层底部离析问题的原因分析与解决方法

On reason analysis and solution methods for bottom segregation of dense wearing course

针对普通沥青磨耗层压实度不足的问题进行了分析,阐述了造成压实度不足的根本原因,探讨了沥青磨耗层底部离析孔洞形成的机理,并提出了有效的解决方法,以期指导今后沥青道路摊铺施工,保证施工质量。

The paper analyzes the insufficient compactness Of the common asphalt dense wearing course, illustrates the basic reasons for the insufficient compactness, explores the formation mechanism for the bottom segregation and holes in the asphalt dense wearing course, and points out the effective solutions, so as to direct the pavement construction on asphalt roads in future and ensure the construction quality.
