High-strength wear-resistant asphalt concrete and production process thereof
The invention discloses high-strength wear-resistant asphalt concrete and a production process thereof, and relates to the field of asphalt concrete.The high-strength wear-resistant asphalt concrete is prepared from, by weight, 6-8 parts of modified asphalt, 45-55 parts of gravel, 25-30 parts of natural sand, 7-9 parts of mineral powder, 5-7 parts of steel slag powder and 0.4-0.8 part of modified microcapsules. The steel slag powder has the advantages of high strength, rough surface, wear resistance, firm combination with asphalt and the like, and meets the use requirements of high-strength wear-resistant asphalt concrete. The compatibility of the modified asphalt and the modified microcapsule is good. The modified asphalt is obtained by modifying asphalt by modified polypropylene into which a hindered phenol structure, a phosphite structure and an alcoholic hydroxyl group are introduced, so that the aging resistance and compressive strength of the concrete are improved. A wrapping material of the modified microcapsule contains DOPO and POSS structures, so that the flame retardance, the high temperature resistance and the self-healing capability of the concrete are improved.
本发明公开了一种高强度耐磨沥青混凝土及其生产工艺，涉及沥青混凝土领域，所述高强度耐磨沥青混凝土包括如下重量份原料：改性沥青6‑8份、碎石45‑55份、天然砂25‑30份、矿粉7‑9份、钢渣粉5‑7份和改性微胶囊0.4‑0.8份。钢渣粉具有强度高、表面粗糙、耐磨与沥青结合牢固等优点，满足高强度耐磨沥青混凝土的使用需求。所述改性沥青与改性微胶囊的相容性良好。所述改性沥青是由引入了受阻酚结构、亚磷酸酯结构和醇羟基的改性聚丙烯对沥青改性得到的，提升混凝土的耐老化性和抗压强度。所述改性微胶囊的包裹材料中含有DOPO和POSS结构，提升混凝土的阻燃性、耐高温性和自愈合能力。
