Asphalt concrete pavement construction method
The invention relates to the technical field of pavement construction, and particularly relates to an asphalt concrete pavement construction method. The method comprises steps of S1, excavating a groove; S2, laying a base layer; S3, laying a cushion layer; S4, paving a first asphalt surface layer; S5, pouring concrete grout on the first asphalt surface layer; S6, paving a second asphalt surface layer; S7, pouring the concrete slurry on the second asphalt surface layer; S8, laying a third asphalt surface layer; S9, pouring the concrete grout on the third asphalt surface layer, wherein a liquidlevel of the concrete grout is higher than that of the third asphalt surface layer to form a concrete surface layer; S10, trowelling the concrete surface layer. The concrete grout comprises componentsin parts, by mass, 100 parts of portland cement; 300 to 400 parts of fine aggregate; 150 to 200 parts of talcum powder; 30 to 35 parts of ethylene glycol monoethyl ether acetate; 3 to 5 parts of 4-methyl-2-pentanone; 0.2 to 0.5 part of acridone; and 90-110 parts of water. The method is advantaged in that the whole road surface is soft, the surface is smooth and flat, driving is comfortable, and the road surface structure is suitable for high-speed driving of vehicles and advanced roads.
本发明涉及路面施工的技术领域，具体涉及一种沥青混凝土路面施工方法，其包括以下步骤：S1.沟槽开挖；S2.铺设基层；S3.铺设垫层；S4.铺设第一沥青面层；S5.第一沥青面层上浇注混凝土浆液；S6.铺设第二沥青面层；S7.第二沥青面层上浇注混凝土浆液；S8.铺设第三沥青面层；S9.第三沥青面层上浇注混凝土浆液，混凝土浆液液面高于第三沥青面层形成混凝土面层；S10.抹光混凝土面层；混凝土浆液包括以下质量份数的组分：硅酸盐水泥100份；细集料300‑400份；滑石粉150‑200份；乙二醇乙醚醋酸酯30‑35份；4‑甲基‑2‑戊酮3‑5份；吖啶酮0.2‑0.5份；水90‑110份。本发明具有路面整体较为柔软且表面光滑平整，行车时较为舒适，且适宜车辆高速行驶，适用于高级道路的效果。
