Resin asphalt concrete and preparation method thereof
The invention discloses resin asphalt concrete and a preparation method thereof, and belongs to the technical field of asphalt concrete preparation. The resin asphalt concrete is composed of a component A, a component B and a component C. The component A is modified asphalt, the component B is a polyurethane cementing material, and the component C is stone with a single particle size. The mass ratio of the component A to the component B to the component C is (100-150): (20-50): (400-800). According to the resin asphalt disclosed by the invention, the thermoplasticity of the asphalt is fundamentally changed, and the prepared resin asphalt mixture has relatively strong rutting resistance, low-temperature deformation performance and adhesion performance, has relatively long operation time at high temperature and can be quickly opened for traffic at normal temperature.
本发明公开了一种树脂沥青混凝土及其制备方法，属于沥青混凝土制备技术领域。所述树脂沥青混凝土由A、B、C三组份组成，其中A组份为改性沥青，B组份为聚氨酯胶结料，C组份为单一粒径石料；所述A、B、C三组份的质量比为100‑150：20‑50：400‑800。本发明的树脂沥青从根本上改变沥青的热塑性，制得的树脂沥青混合料具有较强的抗车辙性能、低温变形性能和黏附性能，且在高温下具有较长的操作时间，常温下又能较快开放交通。
