Low-temperature-resistant cold patch asphalt mixture and preparation method thereof
The invention relates to a low-temperature-resistant cold patch asphalt mixture and a preparation method thereof, the mixture comprises the following raw material components: cold patch asphalt, aggregate and mineral powder, and the cold patch asphalt comprises the following raw material components: asphalt, a diluent, an additive and an anti-stripping agent; the method comprises the following steps: (1) heating asphalt to prepare asphalt liquid; (2) adding a diluent into the asphalt liquid, and stirring to prepare diluted asphalt; (3) adding an additive and an anti-stripping agent into the diluted asphalt at 85-95 DEG C, and uniformly stirring to prepare asphalt mortar; cooling to room temperature to obtain cold patch asphalt; (4) blending the aggregate according to grading, and drying to prepare graded aggregate; and (5) stirring and mixing the cold patch asphalt and the graded aggregate for 90-120 seconds, then adding the mineral powder, and stirring and mixing again for 90-120 seconds. The problem that an existing cold patch material cannot be constructed in the environment of minus 35 DEG C in winter in northern China is solved; the method is simple to operate and convenient to construct, can be used for mixing on site, and can be used immediately.
一种耐低温型冷补沥青混合料及其制备方法，混合料的组成原料组分为冷补沥青、集料和矿粉，其中冷补沥青的原料组分为沥青、稀释剂、添加剂和抗剥落剂；方法为：(1)将沥青加热制成沥青液；(2)稀释剂加入到沥青液搅拌制成稀释沥青；(3)在85～95℃将添加剂和抗剥落剂加入到稀释沥青中，搅拌均匀制成沥青胶浆；冷却至室温获得冷补沥青；(4)集料按级配调和，烘干制成级配集料；(5)将冷补沥青与级配集料搅拌混合90～120s，然后加入矿粉，再次搅拌混合90～120s。本发明解决了现有冷补材料无法在我国北方冬季‑35℃环境下施工的问题；方法操作简单施工方便，可在现场进行拌合，能够达到即使即用。
