Design Guidelines for Epoxy-Modified Recycled Asphalt Pavement (RAP) Mixtures: A Performance-Based Approach
Session
Civil Engineering, Infrastructure and Environment
Description
Recycling reclaimed asphalt pavement (RAP) is widely practiced, yet the reuse of thermosetting epoxy asphalt has not been adequately explored. This study presents design guidelines for incorporating reclaimed epoxy asphalt (epoxy RAP) and diluted epoxy RAP into hot mix asphalt (HMA) mixtures. The study investigates blending behavior between virgin and aged epoxy binders, evaluates total binder content, and proposes a modified mix design protocol for both undiluted and diluted epoxy RAP mixtures. Results show that appropriate mixing and compaction procedures can yield mixtures with acceptable Marshall stability, air voids, and volumetric properties. This work offers practical insights for sustainable pavement construction using epoxy RAP materials.
