摘要:
为利用封装愈合剂实现橡胶沥青路面自修复,通过锐孔凝固浴法制备了封装愈合剂的海藻酸钙自修复微胶囊,并研究了微胶囊的基本物理性能指标、内外结构特征、耐热性能、耐压性能、开裂性能及其橡胶沥青混合料的自愈合性能与路用性能.结果表明:封装愈合剂的海藻酸钙微胶囊在烘干阶段会出现漏油现象,油水比越大,漏油情况越严重,油水比1∶6,1∶8,1∶10的微胶囊强度较高,漏油量较小;海藻酸钙微胶囊内部为多个不规则空腔结构,可以储存囊芯材料,其中,油水比1∶10的微胶囊的性能最优,能够抵御橡胶沥青混合料生产与施工过程中的高温和受力环境,并能在路面开裂时及时破裂;橡胶沥青混合料自身具有一定的自愈合性能,而封装愈合剂能够显著增强橡胶沥青混合料的自愈合能力,并在微胶囊发挥自修复作用后能够显著延长其疲劳寿命.
Abstract:
To heal asphalt-rubber pavement with encapsulated healing agent, alginate self-healing microcapsules were produced by the sharp-hole coagulation bath method. This paper studied the basic physical indicators of microcapsules, internal and external composition characteristics, heat resistance, pressure resistance, cracking potential, as well as the self-healing performance, and pavement performance of asphalt-rubber mixture containing microcapsule. The results show that: the encapsulated healing agent calcium alginate microcapsule leaked some oil during the drying stage. The higher the oil-water ratio, the more serious the oil leakage. The microcapsules with oil-water ratios of 1∶6, 1∶8 and 1∶10 have higher strength and less oil leakage. The alginate microcapsules have multiple irregular cavities inside which could store the core material. The microcapsules with an oil-water ratio of 1∶10 show that the microcapsules with optimal performance can resist the high temperature and mechanical environment of asphalt-rubber mixture during production and construction. Besides, they can rupture in time when cracks on the pavement appear. Asphalt-rubber mixture has a certain self-healing property, while encapsulated healing agent can significantly enhance the self-healing ability of the asphalt-rubber mixture. The microcapsules with the self-repairing of the encapsulated healing agent of the mixture can be extended the fatigue life.
