The asphalt concrete is prepared from the following raw materials in parts by weight: 5-10 parts of asphalt, 20-30 parts of cement, 5-10 parts of fly ash, 50-60 parts of coarse sand, 30-40 parts of fine sand, 20-30 parts of waste plastic particles, 5-9 parts of steel slag, 10-20 parts of metal pipe waste, 5-10 parts of ceramic waste powder and 5-8 parts of reinforced fibers. According to the asphalt concrete, various waste materials can be fully utilized, the recycling value of the waste materials is improved, meanwhile, by controlling the proportion and the specific surface area of the fly ash, the reaction among the raw material components can be effectively promoted, and the obtained product has better strength. Compared with common asphalt concrete, the asphalt concrete provided by the invention also has better wear resistance.
本发明所述的一种沥青混凝土，由如下重量份的原料组成：沥青5～10份、水泥20～30份、粉煤灰5～10份、粗砂料50～60份、细砂料30～40份、废旧塑料颗粒20～30份、钢渣5～9份、金属管废料10～20份、陶瓷废料粉末5～10份、增强纤维5～8份。本发明所述的沥青混凝土能充分各种废旧材料，提高废料的回收利用价值，同时通过粉煤灰的占比和比表面积的控制，可有效促进各原料成分间的反应，得到的产品具有更好的强度。本发明所述的沥青混凝土较普通沥青混凝土而言，还具有更好的耐磨性能。
