Smoke suppression type warm mixing modifier, warm-mixing pouring type asphalt mixture and preparation method
The invention discloses a smoke suppression type warm mixing modifier, a warm-mixing pouring type asphalt mixture and a preparation method. The warm-mixing pouring type asphalt mixture is prepared from mineral aggregate, asphalt and the smoke suppression type warm mixing modifier according to the ratio of 100: 1. (7.0-8.0): (0.5-1.5) through mixing, wherein the asphalt is formed by mixing road petroleum asphalt No. A-70 and low-grade road petroleum asphalt according to a mass ratio of (60-80): (20-40), and the smoke suppression type warm mixing modifier is formed by mixing styrene thermoplastic elastomer, a viscosity reducer, a high-temperature reinforcing agent and a smoke suppression agent according to a mass ratio of (4-6): (2-5): (2-5): (0.3-5). The mixing temperature of the prepared warm-mixing pouring type asphalt mixture is not higher than 200 DEG C, the concentration of asphalt smoke is not higher than 1.0 mg/cm<3>, energy consumption can be reduced, emission of the asphalt smoke is reduced, environmental pollution is reduced, harm to the health of construction operators can be effectively reduced, and the warm-mixing pouring type asphalt mixture is suitable for applicationand promotion.
本发明公开了抑烟型温拌改性剂、温拌浇注式沥青混合料及制备方法，温拌浇注式沥青混合料由矿料、沥青、抑烟型温拌改性剂以100:(7.0～8.0):(0.5～1.5)的质量比混合而成，所述沥青由A‑70号道路石油沥青、低标号道路石油沥青以(60～80)：(20～40)的质量比混合而成，所述抑烟型温拌改性剂由苯乙烯类热塑性弹性体、降黏剂、高温补强剂和抑烟剂以(4～6):(2～5):(2～5):(0.3～5)的质量比混合而成。本发明制备的温拌浇注式沥青混合料拌和温度不高于200℃、沥青烟浓度不高于1.0mg/cm，可减少能源消耗、降低沥青烟的排放，在减少环境污染的同时，可有效降低施工作业人员身体健康伤害，适合推广使用。
