Track-free pavement asphalt modifier as well as preparation method and application thereof
The invention discloses a rut-free pavement asphalt modifier as well as a preparation method and application thereof. The rut-free pavement asphalt modifier is prepared by the following steps: blending and modifying synthetic powder rubber, rubber filling oil and solid novolac epoxy resin by adopting a special millstone-shaped mechanochemical reactor to obtain a mixture A; the mixture B is obtained by grinding a mixed material of long-chain fatty amine, carbon black, sulfur, an accelerant, an antioxidant and an ultraviolet absorbent through a plastic grinding machine, and the rut-free asphalt mixture is prepared through the rut-free pavement asphalt modifier. The rut-free asphalt mixture disclosed by the invention can greatly improve the high-temperature rut resistance and low-temperature crack resistance, can be widely applied to long-life paving of various grades of highway asphalt pavements, bridge floors and tunnels, and is particularly suitable for sections where severe ruts are easy to generate due to long-time action of extra-heavy traffic and creep load.
本发明公开了一种无车辙路面沥青改性剂、其制备方法及应用。本发明所述无车辙路面沥青改性剂由采用特殊磨盘形力化学反应器对合成粉末橡胶、橡胶填充油、固体酚醛环氧树脂进行共混改性后得到的混合物A，与采用塑料磨粉机对长链脂肪胺、炭黑、硫磺、促进剂、抗氧剂、紫外吸收剂的混料进行磨粉得到的混合物B混合后得到，并通过上述无车辙路面沥青改性剂制备无车辙沥青混合料。本发明所述无车辙沥青混合料可大幅度的提高其高温抗车辙性能和低温抗裂性能，可广泛应用于各等级公路沥青路面、桥面、隧道的长寿命铺筑，特别适用于特重交通和蠕形载荷长时间作用易产生严重车辙的路段。
