Abstract

In this paper, the force ductility curve of asphalt which is different contents of SBS and SBS+PPA composite modified asphalt is measured by the force ductility test, and then evaluated the low temperature performance of asphalt before and after aging. Then, Evaluation on low temperature performances of Composite modified asphalt by using related index such as yielding strain energy E, stretching flexibility f, work of fracture W and toughness ratio R. The results showed that with the increasing content of SBS, the low temperature performance of SBS modified asphalt is improved. With the addition of poly-phosphate, the low temperature performance of asphalt become badly, but the low temperature performance of PPA+SBS composite modified bitumen after aging is better than SBS modified asphalt after aging. So PPA can be used as an anti-aging agent.
