水泥乳化沥青冷再生混合料性能评价

摘要

Asphalt pavement cold recycling technique is widely used in China in recent years, mechanics of cold recycling technique is studied in this paper, and it was found that modified emulsion asphalt is better than basic emulsion asphalt. The decision can be made based on the comparison of performance between specimens with different content of cement and asphalt, the result of test indicates that water stability and high temperature stability of cold reclaimed mixture using emulsion asphalt are good.%乳化沥青就地冷再生技术近年在我国得到了较多的应用,在研究了乳化沥青冷再生的机理后,通过对比试验确定改性乳化沥青的性能优于普通乳化沥青,然后分析在不同的水泥用量和乳化沥青用量条件下再生混合料的性能变化,以决定乳化沥青用量及水泥用量,试验结果表明改性乳化沥青冷再生混合料具有较好的高温稳定性和水稳定性.
