Epoxy asphalt mastic macadam mixture suitable for airfield pavement and preparation method thereof
The invention discloses an epoxy asphalt mastic macadam mixture suitable for an airfield pavement and a preparation method thereof. The mixture is prepared from the following raw materials in parts bymass: 0.7 to 2.1 parts of epoxy resin, 0.5 to 1.9 parts of curing component, 2.9 to 7.9 parts of SBS modified asphalt, 100 to 150 parts of mineral aggregate and 0.3 to 0.6 part of fiber. The preparation method comprises the following steps: preheating SBS modified asphalt, adding the preheated SBS modified asphalt into preheated coarse aggregate and fine aggregate determined according to design gradation, adding uniformly mixed epoxy resin and curing component, stirring, finally adding fibers and mineral powder, and stirring. By utilizing the characteristics of high strength, excellent waterdamage resistance, excellent aging resistance and the like of the epoxy asphalt, the prepared epoxy asphalt mastic macadam mixture suitable for the airfield pavement has good strength and durability so that the airfield pavement has good wear resistance, and the risk of wheel track diseases of the asphalt pavement is reduced. The preparation method is simple, energy-saving and environment-friendly, and has relatively high social value and economic value.
本发明公开了一种适用于机场道面的环氧沥青玛蹄脂碎石混合料及其制备方法，混合料由以下质量份的原料制成：0.7~2.1份环氧树脂、0.5~1.9份固化组分、2.9~7.9份SBS改性沥青、100~150份矿料及0.3~0.6份纤维。本发明将SBS改性沥青进行预热，并加入到预热好的按设计级配确定的粗集料、细集料中，再向其中加入混合均匀的环氧树脂和固化组分并搅拌，最后加入纤维和矿粉并搅拌。本发明利用环氧沥青强度高，抗水损性能优良、抗老化性能优异等特点，制备得到的适用于机场道面的环氧沥青玛蹄脂碎石混合料具有良好的强度和耐久性，可使机场道面具有良好的耐磨耗性，降低沥青道面发生轮辙病害的风险。本发明制备方法简单、节能环保，具有较高的社会价值和经济价值。
