A recent study from the Minnesota Department of Transportation identified using recycled asphalt shingles for stabilization or dust control for gravel roads and shoulders. As a test to reduce the dust and to maintain compliance with the Iowa Department of Natural Resources (IDNR) air quality by minimizing dust from the gravel road at the landfill, the landfill purchased ground recycled shingles from Metro Waste Authority. Staff mixed the ground recycled shingles with 1-inch limestone at a 50/50 mixture and spread on the main haul road. The mixture is graded and mixed further. So far, feedback from local haulers is positive, as the blended rock appears to reduce wash boarding and rutting and considerably reduced dust levels. Staff will monitor the test project and if successful Public Works Operations may utilize the rock and recycled asphalt shingles (RAS) mixture on gravel roads within the City limits.
