级配碎石的级配研究

级配碎石作为一种重要的路面材料,其设计方法和性能随着柔性基层沥青路面在我国重新引起重视而越来越被关注。从级配碎石的强度形成机理出发,研究探讨了最大粒径31.5mm的级配碎石的级配设计和使用性能,对级配碎石的设计提供一定的借鉴。

Study of Graduation of Gradated Fragment

As an important material for pavement, the graduated fragment is increasingly followed with interest in its design procedure and performance ,which have been arisen from the flexible base asphalt pavement newly to bring on valuation in our country. The paper makes an approach to the graduation design and service performance of graduated fragment with maximum grain size of 31.5mm, proceed from the mechanism of graduated fragment strength forming,which provide reference to the design of it.
