High-temperature-resistant warm-mixed rubber asphalt mixture as well as preparation method and application thereof
The invention relates to the technical field of road engineering construction, and particularly discloses a high-temperature-resistant warm-mixed rubber asphalt mixture as well as a preparation method and application thereof. The high-temperature-resistant warm mixing rubber asphalt mixture comprises coarse aggregate, fine aggregate, a palmitic acid-lauric acid/vermiculite phase change material, a warm mixing agent, waste rubber powder and matrix asphalt. The palmitic acid-lauric acid/vermiculite phase change material is added into the asphalt mixture, so that the problem of unstable performance of the asphalt mixture in a high-temperature environment is effectively improved; in addition, the asphalt aggregate is also improved, the coarse aggregate with the core-shell structure is obtained by taking the optical fiber waste particles as the core layer and the rubber elastomer as the shell layer, and the rut resistance of the asphalt mixture is effectively improved. According to the invention, the problem of unstable performance of the asphalt mixture in a high-temperature environment in the prior art is effectively solved, and a new design idea is provided for the asphalt mixture used in the high-temperature environment.
本发明涉及道路工程建设技术领域，具体公开了一种耐高温温拌橡胶沥青混合料及其制备方法和应用。所述耐高温温拌橡胶沥青混合料包括粗集料、细集料、棕榈酸‑月桂酸/蛭石相变材料、温拌剂、废橡胶粉和基质沥青。本发明将棕榈酸‑月桂酸/蛭石相变材料加入沥青混合料中，有效改善了在高温环境下沥青混合料的性能不稳定的问题；且本发明还对沥青集料进行改进，以光纤废料颗粒为核层，以橡胶弹性体为壳层得到一种具有核壳结构的粗集料，有效提高了沥青混合料的抗车辙能力。本发明有效解决了现有技术中高温环境下沥青混合料性能不稳定的问题，为在高温环境下使用的沥青混合料提供了新的设计思路。
