The invention belongs to the technical field of traffic, and relates to an asphalt concrete road suitable for heavy traffic and a preparation method thereof. The structure comprises a substrate layer and an asphalt layer, the raw materials of the asphalt layer comprise a component A, a component B and a component C, and the mass ratio of the component A to the component B to the component C is 1: (0.3-0.5): (4-6); the component A is prepared from the following components in parts by mass: 10 to 30 parts of matrix asphalt, 5 to 10 parts of rock asphalt, 100 parts of fine stone with the particle size of 5 to 10 mm, 30 to 300 parts of fine sand with the particle size of 3 to 5 mm, 0.5 to 2 parts of polyphosphoric acid, 0.5 to 2 parts of propylene/alpha-olefin copolymer, 1 to 3 parts of graphite powder and 1 to 3 parts of waste rubber powder; the component B is prepared from the following components in parts by mass: 50 to 80 parts of liquid bisphenol A epoxy resin, 1 to 5 parts of polyethylene glycol diglycidyl ether, 0.1 to 0.3 part of DT-Y polyether modified silicon and 0.1 to 0.3 part of ethylene bis stearamide; and the third component comprises the following components in parts by mass: 100 parts of a curing agent, 0-10 parts of a curing accelerator and 1-2 parts of a coupling agent. Compared with the prior art, the asphalt concrete road suitable for heavy traffic has the characteristics of good compression resistance and high temperature resistance.
本发明属于交通技术领域，涉及到一种适用于重型交通的沥青混凝土公路及其制备方法。其包括基底层和沥青层；沥青层的原料包括甲、乙、丙三种组份，甲、乙、丙的质量比依次为1：(0.3‑0.5)：（4‑6)；甲按质量份计包括：基质沥青10‑30份、岩沥青5‑10份、5‑10mm的细石料100份、3‑5mm细砂30‑300份、0.5‑2份多聚磷酸、0.5‑2份丙烯/α‑烯烃共聚物、1‑3份石墨粉、废旧橡胶粉1‑3份；乙按质量份计包括：液态双酚A型环氧树脂50‑80份﹑聚乙二醇双缩水甘油醚1‑5份﹑DT‑Y聚醚改性硅0.1‑0.3份、乙撑基双硬脂酰胺0.1‑0.3份；丙按质量份计包括：固化剂100份﹑固化促进剂0‑10份﹑偶联剂1‑2份。与现有技术相比，本发明所述的适用于重型交通的沥青混凝土公路具有抗压性能好及耐高温的特点。
