Super-tough epoxy steel slag asphalt mixture and preparation method thereof
The invention discloses a super-tough epoxy steel slag asphalt mixture and a preparation method thereof. The super-tough epoxy steel slag asphalt mixture is prepared from 61-71 parts of basalt coarse aggregate, 33-38 parts of steel slag coarse aggregate, 1-2 parts of mineral powder filler, 4-5 parts of SBS modified asphalt, 0.4-0.6 part of fiber and 4-8 parts of modified epoxy resin. Through the epoxy resin modifier, epoxy condensate can generate microphase separation, the purpose of improving toughness is achieved, the problem that epoxy asphalt steel slag concrete is prone to cracking in a low-temperature environment is effectively solved, and the water stability and low-temperature performance of the epoxy asphalt steel slag mixture are greatly improved.
本发明公开了一种超韧环氧钢渣沥青混合料及其制备方法，包括武岩粗集料61‑71份、钢渣粗集料33‑38份、矿粉填料1‑2份、SBS改性沥青4‑5份、纤维0.4‑0.6份、改性环氧树脂4‑8份。本发明通过环氧树脂改性剂能使环氧固化物产生微相分离，达到了提升韧性的目的，有效解决了环氧沥青钢渣混凝土在低温环境下易开裂的问题，使得环氧沥青钢渣混合料的水稳定性和低温性能有较大提升。
