Foamed asphalt containing sodium hypochlorite oxidized waste tire rubber powder
The invention provides a foamed asphalt containing sodium hypochlorite oxidized waste tire rubber powder, and relates to the field of pavement materials. The foamed asphalt is prepared from, by weight, 40 to 60 parts of SBS modified asphalt, 10 to 15 parts of a zeolite powder/ZnO compound, 20 to 30 parts of ordinary Portland cement, 12 to 18 parts of the sodium hypochlorite oxidized waste tire rubber powder, 10 to 20 parts of fly ash, 1 to 5 parts of a sulfinic acid lactone type foaming agent, 0.1 to 1 part of glycidyl methacrylate, 5 to 10 parts of dimethyl phthalate, 1 to 3 parts of hydroxypropyl methylcellulose, 20 to 30 parts of basalt stone, 50 to 60 parts of aggregate, 2 to 4 parts of pentaerythritol, 5 to 10 parts of reinforced fibers and 12 to 15 parts of a binder. The prepared foamed asphalt is excellent in mechanical properties and high in water stability, the foamed asphalt still has high cohesive force under the action of freeze-thaw cycle, the splitting strength is reducedwithin an acceptable range, and the foamed asphalt is high in rut resistance and suitable for large-scale application.
本发明提供一种含有次氯酸钠氧化废轮胎胶粉的泡沫沥青，涉及路面材料领域，由以下重量份数的原料制备而成：SBS改性沥青40‑60份、沸石粉/ZnO复合物10‑15份、普通硅酸盐水泥20‑30份、次氯酸钠氧化废轮胎胶粉12‑18份、粉煤灰10‑20份、亚硫酸内酯型发泡剂1‑5份、甲基丙烯酸缩水甘油酯0.1‑1份、邻苯二甲酸二甲酯5‑10份、羟丙甲纤维素1‑3份、玄武岩石料20‑30份、集料50‑60份、季戊四醇2‑4份、增强纤维5‑10份、粘结剂12‑15份，本发明制备的泡沫沥青的力学性能出色，水稳定性高，冻融循环作用下泡沫沥青仍有较高的黏结力，劈裂强度降低在可接收的范围内，而且抗车辙能力强，适合大规模应用。
