Low-doped epoxy pure steel slag asphalt mixture and preparation method thereof
The invention discloses a low-doped epoxy pure steel slag asphalt mixture and a preparation method thereof. The low-doped epoxy pure steel slag asphalt mixture comprises 49-60 parts of steel slag coarse aggregate, 34-44 parts of steel slag fine aggregate, 5-7 parts of mineral powder filler, 1.6-2.3 parts of an epoxy system and 4.2-4.9 parts of matrix asphalt. Wherein the steel slag aggregate adopts unaged factory steel slag; the mineral powder is obtained by grinding limestone; the epoxy system is prepared from epoxy resin and a curing agent. According to the invention, the thermosetting property and stronger cohesiveness of the epoxy resin are utilized, and a cross-linked network structure is formed in the asphalt after the epoxy resin is cured, so that the wrapping property of the asphalt on the surface of the steel slag aggregate is improved, the hydration reaction is reduced, and the pavement performance of the mixture is further improved.
本发明公开了一种低掺环氧纯钢渣沥青混合料及其制备方法，包括钢渣粗集料49‑60份、钢渣细集料34‑44份、矿粉填料5‑7份、环氧体系1.6‑2.3份、基质沥青4.2‑4.9份。其中，钢渣集料采用未陈化的出厂钢渣；矿粉采用石灰岩磨细得到的矿粉；环氧体系由环氧树脂和固化剂制备而成。本发明利用环氧树脂的热固性和较强的黏结性，通过其固化后在沥青中形成的交联网络结构，改善沥青对钢渣集料表面的包裹性，减少水化反应的发生，进而提高混合料的路用性能。
