Abstract

In this research, the miscibility of polyvinyl alcohol (PVA) fiber and asphalt under high temperature was explored for improving the performances of PVA/asphalt mixture. Our research shows that the PVA fiber can maintain its properties after heating at 130 oC, which lays a foundation for the mixing of PVA fiber with asphalt. According to this, PVA fibers have been uniformly dispersed in asphalt by an extrusion mixing method at 130 oC. With the addition of PVA fiber, the viscosity, shear strength, complex modulus and rutting factor of the asphalt at high temperature. Besides, the cumulative strain and non-recoverable creep compliance of the PVA/asphalt mixture decreased with the increase of PVA content, which means the PVA/asphalt mixture had a good recovery ability at high temperature. This research provides a basis for the research on miscibility and performance of PVA/asphalt mixture.
