Self-healing asphalt material as well as preparation method and application thereof
The invention relates to the technical field of asphalt, in particular to a self-healing asphalt material and a preparation method and application thereof.The self-healing asphalt material is prepared from asphalt, emulsified asphalt and self-repairing waterborne polyurethane, the emulsified asphalt serves as an emulsifying agent, and the self-repairing waterborne polyurethane serves as a curing agent. The asphalt and the self-repairing waterborne polyurethane are mixed, meanwhile, the self-healing capacity is achieved, the self-repairing waterborne polyurethane serves as a self-healing material, and damage repairing of the self-healing asphalt material is achieved through near-infrared light irradiation. The emulsified asphalt and the self-repairing waterborne polyurethane are adopted to modify the asphalt, so that the self-healing asphalt material with long service life and high self-healing capability is obtained, and the self-healing asphalt material can be directly applied to asphalt pavement paving.
本发明涉及沥青技术领域，具体来说是一种自愈合沥青材料及其制备方法和应用，本发明的自愈合沥青材料由沥青、乳化沥青和自修复水性聚氨酯制成，以乳化沥青作为乳化剂，实现沥青与自修复水性聚氨酯混合的同时具有自身自愈合能力，以自修复水性聚氨酯作为自愈合材料，通过近红外光辐照使自愈合沥青材料实现损伤修复。本发明采用乳化沥青和自修复水性聚氨酯对沥青进行改性，获得长使用寿命、自愈合能力高的自愈合沥青材料，并能够直接将其应用于沥青路面铺设中。
