Self-healing asphalt mixture based on carbon quantum dots/polypyrrole and preparation method
The invention belongs to the technical field of road engineering materials, and particularly relates to a carbon quantum dot/polypyrrole-based self-healing asphalt mixture and a preparation method thereof. The self-healing asphalt mixture comprises mineral aggregate (basalt coarse aggregate, steel slag aggregate, basalt fine aggregate and limestone mineral powder), carbon quantum dot/polypyrrole composite modified asphalt (matrix asphalt, SBS and a carbon quantum dot/polypyrrole composite material) and carbon fibers. The preparation method comprises the following steps: weighing raw materials, and heating the carbon quantum dot/polypyrrole composite modified asphalt to a molten state to obtain heated composite modified asphalt; all mineral aggregates are heated; the heated basalt coarse aggregate, the heated basalt fine aggregate and the heated steel slag aggregate are added into a mixing pot to be stirred, then carbon fibers are added for dry mixing, the heated composite modified asphalt is added, the heated limestone mineral powder is added, stirring is conducted, and the self-healing asphalt mixture is obtained. The microwave heating effect of the asphalt mixture can be optimized, and the self-healing performance of the asphalt mixture is improved.
本发明属于道路工程材料技术领域，具体涉及基于碳量子点/聚吡咯的自愈合沥青混合料、制备方法。自愈合沥青混合料包括矿料(玄武岩粗集料、钢渣集料、玄武岩细集料、石灰石矿粉)、碳量子点/聚吡咯复合改性沥青(基质沥青、SBS、碳量子点/聚吡咯复合材料)、碳纤维。制备方法：称取原料，将碳量子点/聚吡咯复合改性沥青加热至熔融状态，得加热后的复合改性沥青；将矿料都加热；将加热后的玄武岩粗集料、加热后的玄武岩细集料、加热后的钢渣集料加入拌合锅搅拌，再加入碳纤维干拌，加入加热后的复合改性沥青，加入加热后的石灰石矿粉搅拌，得自愈合沥青混合料。本发明能优化沥青混合料的微波加热效果，提高沥青混合料的自愈合性能。
