Asphalt pavement thin-layer water-based repairing adhesive cement and construction process
The invention discloses an asphalt pavement thin-layer water-based repairing adhesive cement and a construction process, the adhesive cement material is composed of water-based cementing material liquid, powder and water, the mass ratio of the cementing material to the powder is (15-25): (85-75), and the water addition amount is 3-5% of the powder. The method is characterized in that the water-based cementing material liquid comprises the following raw materials in percentage by weight: 90-95% of slow-breaking emulsified asphalt, 0.3-0.8% of a tackifier, 5-10% of an SBR + SBS composite modifier and 0.1% of a defoaming agent, wherein the solid content of the slow-breaking emulsified asphalt is 55-65%; and the powder comprises the following raw materials in percentage by weight: 97-99% of 0-3mm machine-made sand, 1-3% of ordinary Portland cement, 1-3% of dispersible rubber powder, 0.1-0.2% of polycarboxylic acid water reducer powder and 0.2% of short acrylic fiber.
本发明公开了一种沥青路面薄层水性修补胶浆及施工工艺，胶浆材料由水性胶结料液体和粉料和水组成，胶结料：粉料质量比=15‑25：85‑75，加水量为粉料的3‑5%，其特征在于：水性胶结料液体包括以下重量百分比的原料：慢裂乳化沥青90%‑95%、增粘剂0.3‑0.8%、SBR+SBS复合改性剂5‑10%、消泡剂0.1%，慢裂乳化沥青的固含量55%‑65%；粉料包括以下重量百分比的原料：0‑3mm机制砂97‑99%，普通硅酸盐水泥1‑3%，可分散胶粉1‑3%，聚羧酸减水剂粉体0.1‑0.2%，短丙纤维0.2％。
