微表处混合料配合比设计方法探讨

Discussion on design method of mix proportion for micro-surfacing

通过研究改性乳化沥青、矿料种类和级配以及混合料油石比,分析了我国现有微表处技术混合料的配合比设计方法。基于此提出了设计关键注意事项,以期提高微表处的路用性能和使用寿命。

By studying the modified emulsified asphalt,the types and gradation of mineral materials,and the ratio of oil and stone,this paper analyzes the design methods of micro-surfacing mixture and proposes the key design considerations in order to improve the road performance and service life of micro-surfacing pavement.
