1 Making Greenways Greener: Developing a Sustainable Trail in Ramsey County Ramsey County 2007 Lower Afton Road Trail Project By Commissioner Victoria Reinhardt and Bridget Beck

2 Deciding to Build a Green Trail Policy Background Citizens want a trail for Bike and Ped Safety Parks and Corrections own the land Segment is short and is a vital connection for the East Metro trail system.

3 Waste Shingles as a Resource Shingles are 15.2% of Construction and Demolition Waste (2006) 300,000 Tons of Roofing Waste per Year 20% of Demolition Landfill Space. (2004) 91% of Residential Roofing Waste is Asphalt Shingles

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 virgin asphalt binder oil –Minimum of 70% virgin asphalt binder in mix

7 LAT Project RAS Spec –Shingles shall be ½-inch minus –Free of nails, other metal, plastic, wood, glass, other debris (less than 0.5 percent) –County to approved plans for: Where to source the tear-off shingles supplies How debris will be sorted out from shingles

8 LAT Project RAS Spec (continued) –Suppilers written certification that the shingles are in compliance –County and Mn/DOT staff shall inspect recycling operations –Samples of final RAS product shall be provided to County and Mn/DOT

9 Source of Sorted Shingles 75% sorted on site at the roofing job –J Zac, Inc. roofing company –Hauled by Veit –Minor contamination 25% supplied from transfer station –Veit Industries –Minimal contamination

26 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

27 Concerns/Lessons Learned With Tear off Shingles Warm weather Wind Ground Shingle stockpile - tacky HMA – tacky
