High-ductility elastic ultrathin overlay asphalt mixture, paving method of asphalt mixture and paved high-ductility and ultra-thin overlay
The invention discloses a high-ductility elastic ultrathin overlay asphalt mixture comprising the following raw materials in parts by weight: 100 parts of asphalt, 25 to 30 parts of modified emulsified asphalt, 58 to 65 parts of coarse and fine aggregate, 4 to 10 parts of filler, 15 to 20 parts of polydimethyl silicone oil and 30 to 40 parts of nano carclazyte. The modified emulsified asphalt is prepared from asphalt, a styrene-butadiene-styrene block copolymer, an emulsifier and a modifier, solves the problems of poor viscosity, poor toughness under a low-temperature condition, small elasticity and loud noise of traditional asphalt, and can significantly enhance the waterproof performance, crack resistance and low-temperature toughness of asphalt micro-surface.
本发明公开了一种高延弹超薄罩面沥青混合料，包括按重量份计的以下原料：沥青100份，改性乳化沥青25‑30份，粗细集料58‑65份、填料4‑10份，聚二甲基硅油15‑20份，纳米白土30‑40份，所述改性乳化沥青由沥青、苯乙烯‑丁二烯‑苯乙烯嵌段共聚物、乳化剂、改性剂制成，解决了传统沥青粘性差，低温条件下韧性差，弹性小，噪音大的问题，能够显著增强沥青微表处的防水性能、抗裂性能以及低温韧性。
