Anti-rut agent modified asphalt, anti-rut and anti-stripping asphalt concrete and preparation method of anti-rut agent modified asphalt
The invention discloses anti-rut agent modified asphalt, anti-rut and anti-stripping asphalt concrete and a preparation method of the anti-rut agent modified asphalt. The anti-rut and anti-stripping asphalt concrete is prepared from the following components in parts by mass: 125-136 parts of anti-rut agent modified asphalt, 5-10 parts of cement, 1-5 parts of an anti-stripping agent, 2-5 parts of polyester fibers, 1800-2200 parts of aggregate, 150-200 parts of mineral powder and 22-26 parts of rock asphalt ash. According to the anti-rutting and anti-stripping asphalt concrete disclosed by the invention, on one hand, the adhesion performance of asphalt and aggregate can be remarkably improved, and the Marshall stability and the freeze-thaw splitting tensile strength of the asphalt concrete and the rutting dynamic stability are improved; on the other hand, the rock asphalt and the ash are effectively utilized as the admixture and/or the internal admixture of the asphalt concrete, so that the material cost is reduced, the stability of the functional agent is prolonged, the excessive use of the chemical functional agent can be reduced, and the ecology is protected.
本发明公开了一种抗车辙剂改性沥青、抗车辙抗剥落沥青混凝土及其制备方法，所述抗车辙抗剥落沥青混凝土由包括如下质量份的组分制备得到：125～136份抗车辙剂改性沥青，5～10份水泥，1～5份抗剥落剂，2～5份聚酯纤维，1800～2200份集料，150～200份矿粉和22～26份岩沥青灰分。本发明所述的抗车辙抗剥落沥青混凝土一方面能够显著改善沥青与集料的粘附性能，提高沥青混凝土马歇尔稳定度和冻融劈裂抗拉强度，及车辙动稳定度；另一方面有效利用岩沥青及灰分作为沥青混凝土的外加剂和/或内掺剂，不仅降低了材料成本，延长了功能剂的稳定性，还能够减少化学功能剂的过度使用，保护生态。
