Alpine region asphalt pavement construction process
The invention provides an alpine region asphalt pavement construction process. The alpine region asphalt pavement construction process comprises the following steps of: preparing a base layer and constructing prime coat oil; measuring a reference line; mixing a mixture; transporting the mixture; paving the mixture; performing joint construction; performing compacting and forming; and protecting and releasing a finished product. According to the alpine region asphalt pavement construction process, mineral powder formed by processing and grinding limestone and the Portland cement are doped into the mixture, so that the temperature-resistant stability of the mixture is improved, the bonding strength of the mixture is improved, the low-temperature resistance of the mixture is improved, and shrinkage deformation in the pavement paving process or after pavement paving can be avoided; and the complete construction process steps of the whole process of transporting, paving and rolling of the mixture are standardized, control over all links and procedures in the construction process is emphasized, the mixture sent to a site is timely paved, rolled and formed on the construction site, it is ensured that the compaction is 100% qualified, and the pavement construction quality is improved.
本发明提供一种高寒地区沥青路面施工工艺，包括以下步骤：基层准备及透层油施工；测定基准线；拌制混合料；混合料运输；混合料的摊铺；接缝施工；压实及成型；成品保护及放行的工艺步骤。采用本发明的技术方案，通过在混合料中掺入由石灰岩加工磨细而成矿粉和硅酸盐水泥，提高了混合料的耐温稳定性，改善了混合料的黏结强度，提升了混合料的耐低温性能，能够避免路面铺设过程中或铺设后出现收缩变形，又通过规范混合料的运输、摊铺、碾压全过程完整的施工工艺步骤，注重施工过程的各个环节、工序的控制，在施工现场对送达现场的混合料及时摊铺碾压成型，确保压实度百分之百合格，提升了路面施工质量。
