摘　　要：以乳化沥青混合料为研究对象,分析了养生时间、温度对混合料含水率(质量分数)、空隙率、劈裂强度的影响,比对了一次压实和二次压实的效果,推荐在满足养生温度不低于60℃的条件下,养生时间不低于24 h,为提升冷再生混合料的施工效率,保证混合料的综合性能提供基础数据支撑。Taking the emulsified asphalt mixture as the research object,the effects of curing time and temperature on the moisture content,porosity,and splitting strength of the mixture are analyzed,and the effects of primary compaction and secondary compaction are compared.Under the condition of the temperature not lower than 60℃,the curing time is not less than 24 h,which provides basic data support for improving the construction efficiency of the cold recycled mixture and ensuring the comprehensive performance of the mixture.
