Treatment of Roadway Runoff Principle Investigators

Wood Filters as an Innovative Treatment Method for Roadway Runoff Pollutants

Stormwater Chemistry and Water Quality

Components of road surface degradation are common constituents of urban runoff. Studies conducted in Europe have indicated that as much as 0.05-0. 10 inch of pavement surface is worn away from the roadway each year. The largest component of street pavement is the aggregate material itself, with additional smaller quantities originating from the asphalt binder, fillers and substances applied to ...

Winter Sand Recollection by Highway Drainage

Abstract Roadway sanding is a common practice in cold regions because sand increases the roadway friction when mixing with snow. However, after snow melt, sand imposes potential hazards to the traffic. Recovery of sand from highways has become an increasing concern not only for the reason of traffic safety, but also for being nonpoint pollution sources to nearby wetlands and streams. In this st...

Finite Element Evaluation of Pervious Concrete Pavement for Roadway Shoulders

Stormwater quantity control is an important issue that needs to be addressed in roadway and ancillary transportation facility design. Pervious concrete has provided an effective solution for storm runoff for parking lots, sidewalks, bike trails, and other applications. It should be readily adaptable for use on roadway shoulders. Being a relatively new material for use in pavement for roadways, ...

The Effect of Roadside Elements on Driver Behavior and Run-Off-the-Road Crash Severity

Roadside vegetation provides numerous environmental and psychological benefits to drivers. Previous studies have shown that natural landscapes can effectively lower crash rates and cause less stress and frustration to the driver. However, runoff the road crashes resulting in a collision with a tree are twice as likely to result in a fatality, thus reinforcing the need to examine the placement o...
