对50%RAP乳化沥青冷再生混合料路用性能进行了试验,介绍了试验所用原材料及配比设计,结合试验方案,对试验结果作了分析,指出试验室内乳化沥青再生混合料需进行60℃温度状态下的35 h养生,施工现场需根据环境进行3 d~7 d的自然养生;各水泥剂量乳化沥青冷再生混合料的强度及高温稳定性都能满足施工要求,水泥剂量为1.5%较经济。 The performance of 50% RAP emulsified asphalt cold reclaimed asphalt mixture was tested. The raw materials used and the proportioning design were introduced. The experimental results were analyzed. The results showed that the recycled emulsified asphalt mixture in the laboratory should be subjected to 60 ℃ 35h health temperature, the site should be based on the environment for 3 d ~ 7 d of natural health; the amount of cement emulsion cold recycle mixture of asphalt mixture strength and high temperature stability can meet the construction requirements, the cement dose of 1.5% economic.
