摘要
玄武岩和石灰石是内蒙古自治区两种常用的筑路材料,在沥青混合料中经常使用,玄武岩具有强度大耐磨耗的优点,石灰岩则具有廉价粘附性好的优点。文章通过改变细集料的岩性,分析玄武岩和石灰岩的改变对沥青混合料性能的影响,分析细集料采用石灰岩和玄武岩的技术指标特性,提出采用两种集料的优缺点,提升沥青混合料的性能。
Basalt and limestone are two commonly used road construction materials in Inner Mongolia Autonomous Region,and are often used in asphalt mixtures.Basalt has the advantages of high strength and wear resistance,while limestone has the advantages of cheap and good adhesion.Through changing the lithology of fine aggregate,this paper analyzes the influence of basalt and limestone on the performance of asphalt mixture,analyzes the technical index characteristics of limestone and basalt used in the fine aggregate,and puts forward the advantages and disadvantages of two kinds of aggregates to improve the performance of asphalt mixture.
