摘要
常规橡胶沥青是一种高效、节能、环保的改性沥青胶结料,但其高温下黏度大,施工和易性与存储稳定性差,而维他连接剂TOR(trans-polyoctenamer rubber reactive modifier)能改善橡胶沥青的性能.制备了常规橡胶沥青和TOR橡胶沥青,并进行高温稳定性、低温抗裂性、弹性恢复性、抗老化性和存储稳定性的对比试验.结果表明,TOR橡胶沥青具有突出的低温抗裂性和存储稳定性.
Conventional asphalt rubber is an effective,energy saving and environmental protection,modified asphalt binder,but its viscosity is very high and its workability and storage stability are poor.TOR（trans-polyoctenamer rubber reactive modifier） can improve the performance of asphalt rubber.In this article,conventional asphalt rubber and TOR asphalt rubber are prepared,and the comparative study on high temperature stability,low temperature cracking resistance,elastic restorative,anti-aging and storage stability is carried out.The results show that TOR asphalt has outstanding low temperature performance and storage stability.
