厂拌冷再生沥青混合料路用性能研究

Research in the road performance of plant mixed cold recycling asphalt mixture

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。

This paper tested the road performance of 50% RAP emulsified cold recycling asphalt mixture, introduced the experiment used raw materials and mix proportion design, combining with the test scheme, analyzed the test results, pointed out that the indoor emulsified asphalt re- cycling asphalt mixture should make 35 h preservation under 60 ℃ temperature conditions, the construction site should make 3 d ～ 7 d natural preservation based on environment, the strength and high temperature stability of each cement dosage emulsified asphalt cold recycling mixture could meet the construction requirements, the cement dosage was 1.5%, more economic.
