Durable asphalt concrete and preparation method thereof
The invention relates to durable asphalt concrete and a preparation method thereof, and belongs to the technical field of concrete materials, the durable asphalt concrete comprises the following raw materials by weight: 50-80 parts of modified asphalt, 30-50 parts of recycled old asphalt, 10-15 parts of coarse gravel, 5-10 parts of fine gravel, and 25-40 parts of cement; the modified asphalt and the recycled old asphalt are used as raw materials, recycling of the materials can be achieved, the environmental protection requirement is met, SBS treated carbon nanotubes are introduced into the modified asphalt, the viscosity of the asphalt can be remarkably improved, the compatibility of the modified asphalt and the recycled old asphalt can be improved, and due to the elastic property of introduced SBS colloidal particles, the mechanical property of the asphalt is improved, and the service life of the asphalt is prolonged. And when internal gaps are frozen and heaved at an extremely low temperature, the freeze-thaw resistance of the permeable asphalt concrete can be improved.
本发明涉及一种耐久沥青混凝土及其制备方法，属于混凝土材料技术领域，包括如下重量份原料：50‑80份改性沥青，30‑50份回收旧沥青，10‑15份粗碎石，5‑10份细碎石，25‑40份水泥；以改性沥青和回收旧沥青作为原料，能够实现材料的回收再利用，复合环保要求，而且本发明中改性沥青中引入SBS处理后的碳纳米管，能够显著提高沥青的粘性，提高改性沥青与回收旧沥青的相容性，而且由于引入的SBS胶粒的弹性性质，在极低温度下发生内部空隙结冰冻胀时，会改善透水沥青混凝土的抗冻融能力。
