橡胶沥青低温性能的研究

Research on Low Temperature Performance of Rubber Asphalt

根据使用经验,我们在分析湿拌法橡胶沥青反应机理中发现,沥青和橡胶粉的反应有化学反应、物理反应,而且反应过程有利于提高沥青的低温性能。通过SHRP试验,对其低温性能进行研究和分析,结果表明,与改性沥青和基质沥青相比,橡胶沥青据有更好的低温性能。

Based on service experience, when analyzing wet mixing method, we discovered that chemical reaction and physical reaction existing in reaction of asphalt and rubber powder in reaction mechanism of rubber asphalt, and that the reaction process is good for improving the low temperature performance of asphalt. Through SHRP test, the research and analysis on its low temperature performance are made. The results show that in comparison with modified asphalt and matrix asphalt, rubber asphalt has better low temperature performance.
