Remediation of Hazardous Effluent Emitted from beneath Newly Constructed RoadSystems and Clogging of Underdrain Systems

摘要

The Indiana Department of Transportation uses recycled concrete pavement asaggregate for the construction of highways. The effluent from these pavements has a high pH. The high pH effluent can cause clogging of drains and vegetative kill around the outlet. This project looks into the source of the effluent water, its chemical composition, and the approximate duration the problem can be expected to persist. The project also investigates possible methods for reduction of the problem in future installation. The approximate additional cost of these solutions and the problems associated with them are discussed as well.
