沥青混合料骨架形成问题的研究

沥青混合料的结构对沥青混合料的路用性能有很大的影响 ,其中骨架密实型与骨架空隙型有很好的高温稳定性 ,悬浮密实型与骨架密实型不透水 ,抗渗性能较好 ,因而耐久性好。一般情况下都希望得到骨架密实型的结构 ,本篇文章研究了骨架的受力规律 ,提出了骨架的形成条件

Study on Problem of Skeleton Formation of Bituminous Mixture

The structure of bituminous mixture has a great influence on the road performance of the bituminous mixture. The skeleton dense type and the skeleton void type have a good stabilization at high temperature. And the suspension dense type and the skeleton dense type are not pervious, they have the better anti permeability property, therefore they have a good durability. In general, all hope to get a skeleton dense type structure. The paper studies on the forced law of the skeleton and puts forward the condition of the skeleton formation.
