Evaluation of Conditions that Cause Negative Environmental Impacts When Using Recycled Concrete Aggregate Status: ActiveProject Start Date: 08/08/2023Subscribe for Updates Summary: This study will benefit MnDOT for the best Recycled Concrete Aggregate (RCA) base application with minimized negative impacts. This includes investigating the effects of aggregate blends, soil type, and layer thickness on the pH of effluent and concentration of leachates over the short and long term. Recommendations will also be made on the minimum distance from the RCA base to the groundwater. Final Deliverables: Related Materials: Related Research:
