Balancing the Performance and Environmental Concerns of

For reclaimed asphalt pavement (RAP) modified with UMO, it was found that UMO offset the aging of the mixture [13] since it compensated the loss of low molecular weight components that volatilized due to short-term and long-term aging. This paper focuses on the effectiveness of using UMO as a rejuvenator in crumb rubber modified asphalt (CRMA)
