Epoxy recycled asphalt mixture and preparation method thereof

Abstract

The present invention discloses an epoxy recycled asphalt mixture and a preparation method thereof, belonging to the technical field of recycling and reutilization of waste asphalt. The present invention realizes 100% efficient regeneration of RAP by optimizing the formulation of the recycling agent, the aggregate pretreatment process, and constructing a compatible epoxy asphalt composite system. The prepared epoxy recycled asphalt mixture has a Marshall stability ≥ 20 kN, a dynamic stability ≥ 10,000 times / mm, and a freeze–thaw splitting strength ratio ≥ 90%. All performance indicators meet the application requirements of highway engineering, providing a green, economical, and high-performance recycled material solution for road engineering, while simultaneously reducing engineering costs and decreasing resource waste and environmental pollution.
