Effect of Road Shoulder Treatments on Highway Runoff Quality and Quantity
This project examined the role that road shoulders play in the stormwater runoff process. The goal of the research was to determine the type of shoulder treatment that yields the least quantity of runoff of the highest quality. Three types of shoulder materials were tested: conventional asphalt, gravel, and porous asphalt. Porous asphalt allows water to penetrate and flow through the pavement to a sublayer, and it can be used in place of conventional asphalt on low-traffic roadways. Each of the three shoulder materials were tested in duplicate on a heavily traveled, two-lane road north of Redmont, Washington. Stormwater runoff from the road flowed onto the shoulder test sections and was collected in a stormwater collection system at the base of the test sections. Flow weighted composite samples were collected, and both runoff quantity and quality were evaluated.
