摘　　要：玻璃沥青混凝土是在普通沥青混凝土中掺入部分碎玻璃作为集料的沥青混凝土。由于国内外在该项目的研究上缺乏可操作性强且统一的规范,对玻璃沥青混凝土的研究也不够深入和系统,所以对玻璃沥青混凝土的研究是一项具有较强前瞻性和实用性的探索性研究。作者通过对不同玻璃掺量的玻璃沥青混合料进行配合比设计、马歇尔试验、路用性能检测试验以及抗滑性能试验等,对比分析不同玻璃掺量的玻璃沥青混合料各项性能的差异,并检验其路用性能是否满足要求。试验结果表明,玻璃沥青混凝土各项路用性能均满足规范要求,完全可以作为一种新型的道路建筑材料。The glasphalt concrete is defined as asphalt concrete containing glass cullet as part of the fine aggregate.As domestic and international research on the project is lack of workable and uniform norms,research on the glasphalt concrete is not thorough and systemic enough,therefore,the study of glasphalt concrete is a forward-looking and practical exploratory study.In order to analyze the different performance of the glasphalt concrete with different account of glass cullet,and to test whether the road performance of the glasphalt concrete meet the specification,systematical tests have been carried out,such as the mix design,Marshall experiment,road performance tests and anti-slide performance test.Experimental results show that the road performance of the glasphalt concrete can meet the requirements of specification,and can be used as a new type of road pavement material.
