摘要
为改善冷补沥青混合料水稳定性能,文章探讨了在道路养护工程中冷补沥青混合料相对于普通沥青混合料的优势,分析了适合冷补沥青混合料的水稳定性评价方法,研究了添加剂对冷补沥青混合料水稳定性的影响。结果表明:抗剥落剂、增粘剂的掺入可有效提升冷补沥青混合料水稳定性,且对提高混合料稳定度有一定作用。
In order to improve the water stability of cold-filled asphalt mixture,this article discusses the advantages of cold-filled asphalt mixture over common asphalt mixture in road maintenance engineering,analyzes the water stability evaluation method suitable for cold-filled asphalt mixture,and studies the effect of additives on the water stability of cold-filled asphalt mixture.The results show that the anti-stripping agent and the thickener can effectively improve the water stability of cold-filled asphalt mixture and have a certain effect on improving the stability of mixtures.
