High-viscosity emulsified asphalt and preparation method thereof
The invention discloses a preparation method of high-viscosity emulsified asphalt, and relates to the technical field of highway and urban road engineering. The high-viscosity emulsified asphalt comprises the following components by weight: 58-70 parts of high-viscosity modified asphalt, 1-10 parts of an emulsifier, 1-5 parts of a stabilizer, 1-5 parts of furfural oil and 30-45 parts of water. Thehigh-viscosity asphalt prepared by the invention is star-shaped block copolymer (SEBS) modified asphalt with high viscosity, so that the problem of bonding with an old pavement structure is effectively solved; additives like furfural oil are added in the preparation process, so that the viscosity of the asphalt at a spraying temperature is reduced, the problem that a nozzle is easily blocked by the asphalt at a lower temperature is solved, and the construction quality is improved.
本发明公开了一种高粘乳化沥青的制备方法，涉及公路与城市道路工程技术领域。包括改性沥青，乳化剂，稳定剂，糠醛油以及水，按重量份计，所述高粘改性沥青58‑70份，乳化剂1‑10份，稳定剂1‑5份，糠醛油1‑5份，水30‑45份。本发明制备的高粘度沥青为采用黏度高的星型嵌段共聚物（SEBS）改性沥青，有效解决与旧路面结构的黏结问题；在制备过程中加入糠醛油等添加剂，降低其在喷洒温度下的黏度，解决在较低温度下沥青容易堵住喷嘴的问题，提高施工质量。
