冷铺沥青材料的特性与配制技术

Behavior and Compounding Technique of Cold-Laid Asphalt Mixture

用冷铺沥青混合料修补路面坑洞,具有方便、快捷等优点。为保证其疏松性和压实性,在配制方法上,如所用沥青的粘度、沥青的用量、添加剂以及集料级配等,与热拌沥青混合料都有很大区别。实践表明,所研制开发的冷铺材料使用性能良好,而成本却比同类进口材料大大降低。

Remedying the pavemenrs chuck holes with cold -laid asphalt mixture has convenient and rapid merits. In order to ensure porosity and compactibility of pavement, the mixture compounding methods such as the viscosity of used asphalt,its consumption, used additive as well as aggregate grading etc are tremendously different from hot - mixing asphalt mixture. Practice indicates that the service performance of developed cold - laid mixture is good, its cost is greatly lower than similar import materials.
