The Hassan - Omann Demonstration project was completed in August of 2006 in the Town of Hassan, Minnesota. The demonstration used both Manufacturer's and Tear-off recycled asphalt shingles (RAS) at 5% and 10% of the total mix. No recycled asphalt pavement was included. The demonstration included RAS in both the wear and base course. For more information review the project reports and Power Point presentations below:
