  4. Collaboration for Results Recognizing the role that everyone plays Public health has the material Public Works has a potential market Parks has a project to help demonstrate the use of post consumer tear off shingles.

  5. Project Overview • Project Consisted of Utilizing Recycled Products • Tear Off Shingles in Bituminous Mix • Recycled Plastics in Retaining Wall • Recycled Plastic/Rubber Pavers • Class 7 Aggregate (“gravel”) base • Reuse of sand in Rain Gardens • Benches have recycled plastics • Utilizing natural soil erosion material • HDPE Pipe • Natural Products

  6. Bituminous Pavement Design • Project was State Aid approved • Mn/DOT Engineered HMA Spec. • Early involvement of Mn/DOT • County required 5% tear off shingles! • Option to have RAP • Utilized type PG 58-28 virgin asphalt binder oil • Minimum of 70% virgin asphalt binder in mix

  10. Omann’s Grinding Process: Phase I • Ground to 8” minus • Removed 95% of nails • Removed most of the remaining contamination

  11. Omann’s Grinding Process: Phases II and III • Removed remaining nails • Removed all metallic material • Ground shingles to a very fine consistency7/16 – inch minus • Provided very clean product to Midwest Asphalt

  12. Bituminous Supplier & Installer:Midwest Asphalt • Utilized oil in shingles as partial replacement of virgin asphalt oil • Used recycled shingles at 5% in place of recycled asphalt pavement (RAP)

  13. Project Notes Normal request for bids Multiple bidders Supports MN/DOT tear-off research Technical feasibility not economic costs and benefits Savings on asphalt binder
