摘要
随着乳化沥青使用性能的提高以及绿色环保、低碳环保理念的践行,乳化沥青在道路工程领域的应用会越来越广泛;对目前乳化沥青应用现状、技术缺陷及发展方向进行了论述。结合现行乳化沥青技术规范,对我国乳化沥青评价方法存在的问题进行了总结;同时,对美国乳化沥青SPG、EPG评价体系的主要框架、评价指标及实施情况进行了对比。
With the improvement of emulsified asphalt performance and the practice of green environmental protection and low carbon environmental protection concepts, emulsified asphalt will be more and more widely used in the field of road engineering. In this paper, the application status, technical defects and development direction of emulsified asphalt are discussed. Combined with the existing emulsified asphalt technology specifications, the existing problems of emulsified asphalt evaluation methods in China are summarized. Meanwhile,the main frame, evaluation index and implementation of the SPG and EPG evaluation system in United States are compared.
