Road construction process
The invention relates to the field of pavement construction, and particularly discloses a road construction process. The road construction process comprises the following steps of S1, leveling a roadbed, and conducting rolling and compaction; S2, paving a concrete base layer on the roadbed, and conducting compacting and curing; S3, paving a pavement layer on the concrete base layer. The concrete base layer in the step S2 comprises the following components in parts by weight: 15-20 parts of Portland cement, 50-70 parts of porous coarse aggregate, 3-8 parts of reinforced fibers, 13-18 parts of epoxy resin, 5-8 parts of a curing agent and 0.5-1 part of a polycarboxylic acid water reducing agent. By increasing the use amount of the coarse aggregate and removing the fine aggregate, pores can be naturally formed in the concrete, meanwhile, the porous coarse aggregate is adopted, water permeation can be facilitated, meanwhile, the bonding effect with the coarse aggregate can be improved by using the efficient polycarboxylic acid water reducing agent and the cement, meanwhile, the epoxy resin and the curing agent are added to serve as another cementing material, and the epoxy resin has a good gelling effect and can significantly improve the strength of the concrete base.
本申请涉及路面建设领域，具体公开了一种道路施工工艺。道路施工工艺包括以下步骤：S1、对路基进行平整并碾压压实；S2、在路基上铺设混凝土基层，并压实养护；S3、在混凝土基层上方铺设路面层；所述S2步骤中的混凝土基层包括以下重量份的组分：15‑20份硅酸盐水泥、50‑70份多孔粗骨料、3‑8份增强纤维、13‑18份环氧树脂、5‑8份固化剂、0.5‑1份聚羧酸减水剂。本申请通过提高粗骨料的用量，去除细骨料，使混凝土中能够自然形成孔隙，同时采用多孔的粗骨料，能够便于水分的渗透，同时用高效的聚羧酸减水剂和水泥能够提高与粗骨料的粘合效果，同时添加环氧树脂和固化剂作为另一种胶凝材料，环氧树脂的胶凝效果好，能够显著提高混凝土基层的强度。
