Municipal road construction method
The invention discloses a municipal road construction method. The municipal road construction method comprises the steps that (1) earth excavation is carried out; (2) a concrete base layer is laid, specifically, the bottom of the earthwork is raked, a reinforcing mesh is laid, anti-seismic concrete is poured, and the concrete base layer is formed after tamping and curing; (3) a gravel cushion layer is laid; and (4) an asphalt surface layer is laid. The anti-seismic concrete comprises the following components in parts by mass: 80 parts of polyethylene, 25 to 35 parts of emulsified asphalt, 30 to 40 parts of a polyurethane adhesive, and 60 to 80 parts of fine aggregate. In this way, the method has the advantage that a road is high in anti-seismic capacity.
本发明公开了一种市政道路施工方法，包括以下步骤：(1)土方开挖；(2)铺设混凝土基层，具体如下：耙松土方底部，铺设钢筋网，浇筑抗震混凝土，捣实，固化后形成混凝土基层；(3)铺设砂石垫层；(4)铺设沥青面层；所述抗震混凝土包括以下质量份数的组分：聚乙烯80份；乳化沥青25‑35份；聚氨酯胶黏剂30‑40份；细集料60‑80份。通过上述方式，本发明具有道路抗震能力较强的优点。
