Abstract
In seasonal frozen region, the performance of asphalt pavement is affected severely by the freeze-thaw cycles. The binder is the first factor that affected by these cycles. The objective of this study is to evaluate the performance of EVA polymer modified bitumen after freeze – thaw cycles. Before and after thermal cycling, the complex modulus and phase angle, creep and recovery, also m-value and creep stiffness, were experimentally determined by the rheometers DSR and BBR. Results obtained indicate that freezing – thawing cycles change the rheological behavior of polymer modified bitumen, which translated in reducing the performance of this binder.
