New asphalt additives have been developed at Mizzou, combining waste plastics, bio-resins, and other recycled additives, creating rubbery materials distinct from conventional recycled plastics. The softened plastic in these products enhance crack resistance in cold weather, while their combined use with other recycled materials such as original, unsoftened waste plastic, ground tire rubber (GTR), reclaimed asphalt pavement (RAP), and recycled asphalt shingles (RAS) improves resistance to deformation under heat and heavy traffic. The team will focus on scaling production, transitioning from lab-scale to pre-pilot operations. Approximately 6,000 lbs of the additive will be produced for a demonstration project constructed in Missouri, demonstrating the products performance under real-world conditions.
