乳化沥青冷再生技术对于废旧沥青混合料的循环利用具有重要意义。为了研究乳化沥青的工程性质，进行了乳化沥青‐水泥冷再生沥青混合料的配合比设计，并通过击实试验、马歇尔稳定度试验、密度试验、劈裂试验、无侧限抗压强度试验，对其路用性能进行了评价，确定了其最佳含水量和最大干密度。结果表明：各项路用性能技术指标均满足规范要求；手工拌合方式的干密度要小于通过机械拌和方式合料的干密度。因此建议室内拌和混合料时，宜采用机械拌和方式。

The emulsified asphalt cold recycling technology for the recycling use of waste asphalt mixture is of great significance .In order to study its engineering properties ,the emulsified asphalt and concrete mixture proportioning was designed .Through the compaction test ,Marshall stability ,density test ,splitting test and unconfined compressive strength test ,the pavement performance was evaluated ,and the optimum water content and maximum dry density were acquired .The results show that the pavement performance evaluation technical indexes all meet the requirements of specification .The density of mixing by hand is less than that by machine . Therefore ,this paper suggests that the mixing by machine should be more adopted when the mixture is made indoors .
