摘要
RET是美国杜邦公司研发的一种新型沥青化学改性剂,通过与沥青中的分子和官能团发生化学反应,从而达到改善沥青使用性能的效果。通过分析研究不同种类改性沥青的Superpave性能试验结果及老化前后的低温PG分级温度及质量损失,表明RET改性剂能够明显改善沥青的高温稳定性和低温抗裂性。
RET（Reactive Elastomeric Terpolymer） is a kind of chemical modifier that was developed by Dupont, it can react with asphalt molecules and functional groups to improve the functional performance of the asphalt. In this paper, Superpave performance test results, low temperature PG grading temperature and mass loss before and after aging of different types of modified asphalt were analyzed and researched. The results show that RET modifier can significantly improve asphalt high temperature stability and low temperature crack resistance.
