摘要:
为了进一步促进微胶囊自修复技术在中国道路工程领域中的发展与应用,综合国内外最新研究成果对沥青混合料微胶囊自修复技术展开全面的分析,总结微胶囊自修复技术的基本原理、研究现状及进展,系统梳理了自修复微胶囊的性能表征方法、掺加微胶囊沥青材料的自修复性能评价方法,并重点分析不同评价方法的优点与不足。在此基础上,从囊芯材料的选择、囊壁材料的研发、微胶囊的粒径与形状等3个方面概述沥青混合料自修复微胶囊的设计方法;介绍了沥青混合料微胶囊自修复技术的最新室外试验研究进展。结果表明:当前沥青混合料微胶囊自修复技术研究中存在着路用性能研究不系统、评价方法不成熟、微胶囊设计方法不完善等问题;下一步应开展通过数值模拟的方法探讨微胶囊在沥青混合料中的多维受力特性,为微胶囊的精细化设计提供可靠的理论〖JP2〗依据;开发能够多次缓释、高耐久性的自修复微胶囊,使其可以在整个路面预养护周期内发挥自修复作用;研发复合自修复路面养护技术,实现沥青路面在预养护阶段不同时间节点的按需自修复。
Abstract:
〖WTBZ〗〖HQK〗In order to further promote the development and application of the selfhealing technology of microcapsules in the field of Chinese road engineering, the newest research on the selfhealing technology of asphaltmixture microcapsules at home and abroad were comprehensively analyzed. The basic principle, research status and progress of selfhealing technology of microcapsules were summarized. The performance characterization method of selfhealing microcapsules and the selfhealing performance evaluation method of the asphalt material with microcapsules were systematically hackled. And the merits and demerits of different evaluation methods were emphatically analyzed. On this basis, the design methods of the selfhealing microcapsules of asphalt mixture were summarized from three aspects, namely the selection of capsulecore materials, the development of capsulewall materials and the particle size and shape of microcapsules. The latest outdoor study advances of the selfhealing microcapsules of asphalt mixture were introduced. The results show that some problems of the selfhealing technology microcapsules of asphalt mixture in current researches are pointed out, for instance, studies on road performance are not systematic, the evaluation methods are immature, and the design methods of microcapsules are imperfect. And the tendency of the research is to discussed the multidimensional force characteristics of microcapsules in asphalt mixture through the numerical simulation method, which provides reliable theories for the fine design of microcapsules, many times released and high durable microcapsules are developing to play the selfhealing role during the whole pavement premaintenance cycle; the maintenance technology of composite selfhealing pavement is researched and developed to achieve selfhealing of asphalt pavement in suitable time during the premaintenance period. 1 tab, 5 figs, 51 refs.
