Characterization of Runoff Quality from Paved Low-Volume Roads and Optimization of Treatment Methods , released by the University of Minnesota

The Texas Department of Transportation had a rare opportunity to investigate how pavement type affects the quality of stormwater runoff, something that is often difficult to address in the limited space available in highway rights-of-way. The research showed that roadways paved with permeable friction course/open-graded friction course (PFC/OGFC) produced runoff with substantially reduced conce...

Faced with ever-increasing regulatory scrutiny and a realization that traditional stormwater management approaches largely were ineffective in a transportation setting, stormwater professionals at the Alabama Department of Transportation (DOT) began to explore approaches that were outside of those prescribed by regulation and existing guidance materials. Based on these experiences, the Alabama ...
