为了深入研究乳化沥青水中浸出性能于沥青混合料性能相关性,通过IR分析表明,阳离子乳化沥青浸出前后组分组成并未变化,但组分比例却有一定改变;阳离子乳化沥青三大指标试验结果表明阳离子乳化沥青浸出前后针入度、延度和软化点都有所变化,其中针入度和延度随浸泡时间的延长而呈减小变化,软化点则随浸泡时间的延长而呈增加变化趋势;乳化沥青冷再生混合料劈裂强度、低温弯曲及高温车辙试验结果表明浸泡对乳化沥青冷再生试件有一定影响,随浸泡时间的延长混合料的劈裂强度、低温性能和高温性能都会有所降低。
In order to further study the leaching performance of emulsified asphalt water on the performance of asphalt mixture, IR analysis showed that the composition of the cationic emulsified asphalt did not change before and after leaching, but the composition ratio has changed; cationic emulsified asphalt test results of the three indicators The results showed that the penetration, ductility and softening point of cationic emulsified asphalt changed before and after leaching, and the penetration and ductility decreased with the prolongation of soaking time, while the softening point increased with the prolongation of soaking time The results show that the soaking has a certain influence on the cold recycled samples of emulsified asphalt, and the splitting strength, the low temperature and the high temperature performance of the mixture will be prolonged with the soaking time Decreased.
