| Abstract: | The basic property of the base material with the inter-stitial was introduced.On the basis of aboundant experiment,it was expounded that the road base with inter-stitial spall in Zhangwu area could completely met the engineering requirement.By using uniform design to design experiment,the experiment of solid volume rate of the material was proceeded,which determined the optimum value 78.845.It also proposes the innovative method of indoor load experiment,introduces the way and step,and gives the p-s curve c... |
