Semi-flexible asphalt mixture filled with metakaolin-based geopolymer and preparation method of semi-flexible asphalt mixture
The invention discloses a semi-flexible asphalt mixture filled with a metakaolin-based geopolymer. The semi-flexible asphalt mixture is composed of a macropore open-graded asphalt mixture matrix and a metakaolin-based geopolymer grouting material filled in the macropore open-graded asphalt mixture matrix, wherein the grouting material is prepared by compounding metakaolin, an alkali activator, fly ash, graphene, styrene-butadiene emulsion, a silane coupling agent and sand, so that the volume stability, compactness and mechanical toughness of a slurry material can be improved, and the early cracking tendency of slurry is reduced; the problems that a traditional cement-based grouting material is low in interface bonding strength, poor in volume stability, low in fluidity and the like are effectively solved, production energy consumption and carbon emission can be further reduced, and the product is suitable for application and popularization.
本发明公开了一种填充偏高岭土基地聚合物的半柔性沥青混合料，它由大孔隙开级配沥青混合料基体和填充在其中的偏高岭土基地聚合物灌浆料组成；其中灌浆料利用偏高岭土、碱激发剂、粉煤灰、石墨烯、丁苯乳液、硅烷偶联剂和砂进行复配而成，能够提高浆体材料的体积稳定性、致密性、力学韧度，降低浆体早期开裂的倾向，有效解决传统水泥基灌浆材料界面粘结强度低、体积稳定性差、流动性低等问题，并可进一步降低生产能耗和碳排放量，适合推广应用。
