Abstract

Abstract: The purpose is to improve performance of asphalt by synergistic enhancement of graphene and tourmaline. Graphene/tourmaline composite modified asphalt was prepared. The basic properties and rheological properties of graphene/tourmaline composite modified asphalt were analyzed systematically. The results indicate that the basic viscoelastic properties of asphalt were not destroyed after graphene/tourmaline composites added into asphalt. The rutting resistance of graphene/tourmaline composite modified asphalt was superior than tourmaline. And the larger the composite material content, the superior the rutting resistance of modified asphalt. The rutting resistance was increased by 10.12%.
