Normal-temperature rapid early-strength high-performance asphalt cold patch material and preparation method thereof
The invention discloses a normal-temperature rapid early-strength high-performance asphalt cold-patch material and a preparation method thereof, and the asphalt cold-patch material comprises the following substances in percentage by mass: 80-86 wt% of aggregate, 7.5-11 wt% of mineral powder, 0.5-1 wt% of cement, 0.5-1 wt% of slaked lime, 0.2-0.4 wt% of bentonite, 0.2-0.4 wt% of lignin fiber and 5-7 wt% of asphalt cold-patch liquid, d40 dearomatization solvent naphtha or a mixture of D40 dearomatization solvent naphtha and D60 dearomatization solvent naphtha is used as a diluent in the asphalt cold supplementing liquid. The method comprises the following steps: preparing asphalt cold supplementing liquid; drying the aggregate, the mineral powder, the cement, the slaked lime and the bentonite; putting the aggregate, the cement, the slaked lime, the bentonite and the lignin fiber into a mixing pot and stirring; adding the asphalt cold supplementing liquid into the mixing pot and stirring; and adding the mineral powder into the mixing pot, and stirring to obtain the rapid early-strength high-performance asphalt cold patch material at normal temperature. The asphalt cold-patch material disclosed by the invention can quickly form strength within an extremely short time, ensures quick passage after pit slot repair, and maximally reduces the influence of traffic transportation.
本发明公开了一种常温下快速早强高性能沥青冷补料及其制备方法，该沥青冷补料中各物质的质量百分比为，集料80‑86wt％、矿粉7.5‑11wt％、水泥0.5‑1wt％、消石灰0.5‑1wt％、膨润土0.2‑0.4wt％、木质素纤维0.2‑0.4wt％、沥青冷补液5‑7wt％，沥青冷补液采用D40脱芳烃溶剂油或D40脱芳烃溶剂油与D60脱芳烃溶剂油的混合物作为稀释剂。该方法包括以下步骤：制备沥青冷补液；对集料、矿粉、水泥、消石灰、膨润土进行烘干处理；将集料、水泥、消石灰、膨润土、木质素纤维放入拌合锅中搅拌；将沥青冷补液加入拌合锅中搅拌；将矿粉加入拌合锅中搅拌，即获得常温下快速早强高性能沥青冷补料。本发明的沥青冷补料能在极短时间内快速形成强度，保证坑槽修补后快速通行，最大限度降低交通运输影响。
