【摘要】：为了研究与比较不同温拌技术的温拌效果,选择有机添加剂类、沸石类、乳化沥青温拌技术和表面活性技术等不同原理的温拌剂,对SBS改性沥青、橡胶沥青两种沥青混合料进行试验研究,分析不同温拌剂的温拌效果及其对混合料路用性能的影响。研究表明,几种温拌剂均能显著降低SBS改性沥青、橡胶沥青混合料的拌合与压实温度;不同温拌剂对沥青混合料路用性能的影响差异显著,有机添加剂类能较好地改善混合料的高温和水稳性能,但对其低温性能不利;沸石类和乳化沥青温拌剂能显著改善混合料的低温性能,对高温和水稳性能无明显影响;表面活性温拌剂能改善混合料的低温和水稳性能,对高温性能改善不明显。
[Abstract]:In order to study and compare the warm mixing effect of different warm mixing technologies, the SBS modified asphalt was modified by using different warm mixing agents, such as organic additives, zeolite, emulsified asphalt warm mixing technology and surface activity technology, etc. Two kinds of asphalt mixture of rubber asphalt were tested to analyze the effect of different warm mixing agent and its influence on the pavement performance of the mixture. The results show that the temperature of mixing and compaction of SBS modified asphalt and rubber asphalt mixture can be significantly reduced by several warm mixing agents, and the influence of different warm mix agents on the pavement performance of asphalt mixture is significant. Organic additives can improve the mixture's high temperature and water stability, but it is not good to its low temperature performance, zeolite and emulsified asphalt warm mix agent can improve the mixture's low temperature performance, but have no obvious influence on the high temperature and water stability. The surface active warm mix agent can improve the low temperature and water stability of the mixture, but it can not improve the high temperature performance obviously.
