Preparation method of anti-cracking rock rubber powder composite modified asphalt mixture
The invention discloses a preparation method of an anti-cracking rock rubber powder composite modified asphalt mixture. The preparation method comprises the following steps: step 1, preparing a mixture; 2, preparing modified asphalt; 3, mixing and stirring the mixture and the modified asphalt; and step 4, preparing kaolin. The rock rubber powder, the waste rubber, the polyethylene wax, the petroleum asphalt and the thermoplastic resin are adopted to improve the anti-aging performance, the adhesion performance and the high-temperature stability of the modified asphalt, and the slaked lime is adopted as the filler to effectively improve the water stability of the modified asphalt mixture and improve the high-temperature resistance, the low-temperature crack resistance and the fatigue resistance of the modified asphalt mixture. The sand is particles ground from stones or artificially manufactured silicon dioxide particles, the compactness and strength of the asphalt mixture can be improved, the waste rubber and the waste nylon fibers are adopted as raw materials, the cost is low, manufacturing is convenient, the pollution problem of the waste rubber and the waste nylon fibers is solved, and the requirement for environmental protection is met.
本发明公开了一种抗开裂的岩胶粉复合改性沥青混合料的制备方法，包括以下步骤：步骤一、制备混合料；步骤二、制备改性沥青；步骤三、将混合料与改性沥青混合搅拌；步骤四、制备高岭土；通过采用岩胶粉、废橡胶、聚乙烯蜡、石油沥青和热塑性树脂提高了改性沥青后的抗老化性能、粘附性能和高温稳定性能，通过采用消石灰作为填料能够有效提高改性沥青混合料的水稳定性，改善其耐高温性能、低温抗裂性和抗疲劳性能，砂子是从石块上打磨下来的颗粒或人工制造的二氧化硅颗粒，能够改善沥青混合料的密实性和强度，通过采用废橡胶、废尼龙纤维为原料，成本低廉，制造方便，并且解决了废橡胶、废尼龙纤维的污染问题，满足环境保护的要求。
