Fast pavement containing environment-friendly high-doping-amount RAP regenerated cement stable mixture base and construction technology thereof
The invention belongs to the technical field of cement stabilized macadam mixture preparation and application, and particularly relates to an expressway pavement containing an environment-friendly high-mixing-amount RAP regenerated cement stabilized mixture base layer and a construction technology thereof.The expressway pavement comprises a surface layer, a base layer and a roadbed which are sequentially arranged from top to bottom, and the base layer comprises an upper base layer, a lower base layer and a subbase layer; the laying material of the upper base layer and the laying material of the lower base layer are environment-friendly high-dosage RAP regenerated cement stable mixtures, and the laying material of the subbase layer is lime-fly ash gravel mixtures. Through the structural combination of double-base-layer continuous paving, compared with a construction project of a common cement-stabilized base layer, the construction period can be shortened by 85%, early asphalt pavement diseases such as local segregation, loosening and rutting are not prone to occurring on the pavement, and the practical use value is very high.
本发明属于水泥稳定碎石混合料制备和应用技术领域，具体涉及一种含环保型高掺量RAP再生水泥稳定混合料基层的快速路面及其施工工艺，其中快速路面包括从上到下依次设置的面层、基层和路基，所述基层包括上基层、下基层和底基层；所述上基层和下基层的铺设材料为环保型高掺量RAP再生水泥稳定混合料混合料，所述底基层的铺设材料为二灰碎石混合料。通过双基层连铺的结构组合，相对于普通的水稳基层的施工项目，可缩短工期达到85%且路面不易出现局部离析、松散、车辙等早期沥青路面病害，具有很强的实际使用价值。
