摘要
研究了集料特性对改性乳化沥青乳液在混合料初始拌和阶段破乳过程的影响,以及集料特性对水-温耦合作用下微表处混合料路用性能的影响,揭示了集料酸碱性、表面电荷特性、接触角差等技术特性对微表处混合料的影响机理,并结合微表处混合料施工性能和路用性能试验结果推荐了不同岩性集料微表处混合料的适用性,为微表处混合料原材料选择以及路用性能的评价方法起到一定的完善和补充作用。
This article studied the affect of aggregate characteristics on modified emulsified asphalt emulsion mixture initial mixing stage in the process of breaking,And the effect of aggregate characteristics on road performance of micro-surfacing mixture under the action of the water-temperature coupling. Revealing the Influence mechanism of aggregate p H,surface charge impact mechanism features,technical characteristics and contact angle on the micro-surfacing mixture. Combined with the construction and road performance test results of micro-surfacing mixtures,this article recommended the applicability of different aggregate micro-surfacing mixture. Research results for the micro-surfacing Mixture selection of raw materials and pavement performance evaluation methods to improve and play a complementary role.
