乳化沥青冷再生混合料性能研究

Research on the Performance of Emulsified Asphalt Cold Recycling Mixtures

文章对不同乳化沥青用量和不同水泥掺量的冷再生混合料路用性能进行比较分析,结果表明,水泥可以提高乳化沥青冷再生混合料水稳定性、早期强度和高温稳定性;水泥用量过高时会导致冷再生混合料变脆,降低混合料的低温抗裂性能;低乳化沥青用量冷再生混合料具有很好的高温抗车辙性能,满足我国再生技术规范中的相关要求。

In this paper, road performance of cold recycling mixtures with different amount of emulsified asphalt and cement is analyzed and compared. Results show that the cement can improve water stability, early strength and high temperature stability of emulsified asphalt cold recycling mixture; while high cement content will cause mixture brittle, reduce low temperature crack resistance; cold recycled mixture with low emulsified asphalt has better high temperature anti-rutting performance which can meets specifications technical requirements.
