Slag-gypsum-based cementing material and stabilized macadam three-layer continuous paving construction process thereof
The invention relates to the field of infrastructure construction, and particularly discloses a slag-gypsum-based cementing material and a stabilized macadam three-layer continuous paving construction process thereof. The slag-gypsum-based cementing material comprises 75-85 parts of slag powder, 10-20 parts of industrial byproduct gypsum, 1-5 parts of an alkaline component, 0.2-0.5 part of modified mixed fibers, 2-4 parts of a composite activator, 0.1-0.3 part of triethanolamine and 0.4-0.6 part of resin, wherein the modified mixed fibers are obtained by mixing basalt fibers subjected to chemical modification with polyethylene fibers; the laying process mainly comprises the following steps: (1) constructing the lower bearing layer; (2) mixing the raw materials; (3) paving and rolling construction; and (4) later maintenance. The composition provided by the invention can be used for pavement paving construction, has stable anti-cracking strength, and is suitable for multi-layer paving of large-volume highway stabilized macadam.
本申请涉及基础设施建设领域，具体公开了一种矿渣‑石膏基胶凝材料及其稳定碎石三层连铺施工工艺。矿渣‑石膏基胶凝材料包括矿渣粉75‑85份、工业副产石膏10‑20份、碱性成分1‑5份、改性混合纤维0.2‑0.5份、复合激发剂2‑4份、三乙醇胺0.1‑0.3份、树脂0.4‑0.6份，所述改性混合纤维是通过将玄武岩纤维经化学改性后与聚乙烯纤维混合得到；其铺设的工艺主要包括（1）下承层的施工；（2）原料拌合；（3）摊铺碾压施工；（4）后期养护。本申请的组合物可用于路面铺设施工，其具有稳定的抗裂强度，适于大体积公路稳定碎石的多层摊铺。
