1.前言水稳碎石作为路面基层,厚度一般均在30cm以上,按照传统的施工方法水稳碎石分层摊铺,分层养护,占用时间长,直接影响到整个工程的工期;同时,分层摊铺施工,若两层之间处理不好易形成分层,难以形成整体受力,降低其工作性能。分次摊铺一次成形可保证其整体性又可缩短工期,降低成本。尤其在城市道路改造过程中可以 1. Introduction Water-stabilized gravel as the pavement base, the thickness are generally above 30cm, according to the traditional method of construction of water-stabilized gravel layered pavement, layered maintenance, take a long time, a direct impact on the entire project duration; the same time, Layered paving construction, if the two layers are not easy to deal with the formation of stratification, it is difficult to form the overall force, reducing its performance. Sub-paving a forming can ensure its integrity but also shorten the construction period and reduce costs. Especially in the urban road reconstruction process can be
