摘要
针对地方公路铣刨料沥青含量小,粒径偏细的现状,通过变化水泥、乳化沥青用量或集料组成,研究了乳化沥青冷再生混合料的多项性能指标,并对试验结果进行对比分析。结果表明通过调整级配组成中的水泥、乳化沥青用量及新集料组成,对使用地方公路铣刨料的冷再生混合料整体性能有明显改善。
According to the situation that reclaimed asphalt pavement from local road is have little as- phalt content and particle size is fine, by changing the composition of emulsified asphalt or cement, aggregate, several performance indexes of emulsified asphalt cold recycled mixture, and the experimental results were compared and analyzed. The results show that by adjusting the composition of cement, emulsified composition the amount of asphalt and aggregate, and obviously improve the use of cold recycled mixture of local road mill- ing materials overall performance.
