对《公路沥青路面再生技术规范》（JTG F41-2008）中乳化沥青冷再生混合料试验规程中的最佳含水率OWC的确定方法以及试件成型的养生温度等进行改进，以完善和简化规范要求的试验方法，并通过室内试验对改进后的试验方法进行验证和对比研究。研究表明，使用最佳流体含量OFC作为乳化冷再生混合料外加水的控制指标优于规范要求的最佳含水量OWC指标；提高试验养生温度至110℃，可以获得与规范60℃养生温度相似的结果，并能够缩短试验所需时间，提高工作效率；乳化沥青冷再生混合料具有较好的水稳定性能及高温稳定性能，能满足或高于热拌沥青混合料的技术要求。

In this paper,the determination method of OWC(optimum water content)and the specimens curing temperature stipulated by cold recycling mixture test procedures of emulsified asphalt in“Technical Specifica-tions for Highway Asphalt Pavement Recycling”were ameliorated to improve and simplify the test methods. Some laboratory tests and comparative study were carried out to verify them. The results show that:(1)Using OFC(opti-mum fluid content)as the optimum water content control index of the emulsified asphalt cold recycling mixture is superior to OWC that required by specification;(2)The similar results can be obtained when the curing tempera-ture is improved from 60℃to 110℃,and the test time can be decreased greatly and the work efficiency can be im-proved;(3)The water stability and the high temperature stability of the mixture are superior to HMA to some ex-tent.
