Recycled Concrete Aggregate (RCA) for Infrastructure Elements

The objective of this research was to determine the implications of using RCA in the production of new concrete. Specifically, the study evaluated the fresh and hardened properties, durability, and structural behavior of concrete containing RCA and, based on these results, developed guidelines on its use in infrastructure elements for MoDOT.

The report consists of a summary report with appendices comprising five detailed technical reports. Taken together, these reports document the background, detailed approaches, experimental procedures and processes, results, findings, conclusions, and recommendations of the study.
