These mix designs were accelerated performance tested in the lab.

The preparation of mix designs kept the total asphalt content constant, adjusting aggregate gradation to accommodate RAP and various portions of RAS. Grade A, 80 -100 Pen asphalt cement was used.
Each mix design was evaluated for volumetric properties, Marshall properties, and penetration of asphalt cement.

For the trial, Metro Vancouver is using RAS from S&G ReMan Recyclers of Kelowna. Unfortunately, adequate shingle recycling capacity that met quality specifications used by pavers in the US and Canada was not in place in the Lower Mainland when the trial started. Local recycling options will be available soon. S&G ReMan Recyclers in Kelowna, BC and Johal Brothers in Lake Cowichan, BC produce RAS that meets the quality specifications.

If you’re a roofer, waste hauler, recycling or disposal facility, asphalt producer, pavement engineer, or developer seeking LEED™ certification, you’ll find useful contacts on page 2 and in the EcoWaste information on this page.

Gemaco Sales Ltd. is pleased to announce plans to open a Shingle Recycling Facility in Annacis Island Industrial Park by summer 2010. Gemaco will adopt operating procedures from the Construction Material Recycling Association’s “Best Practices Guide” for recycling tear-off shingles. These include controls and testing to keep the product free of asbestos as well as measurement of the asphalt cement content (typically 22 - 27%).

M -Tec plans to open a shingle recycling operation by mid-2010. Locations in Surrey or Richmond are being considered. The M -Tec team includes a recycler with four years of experience recycling asphalt shingles in Halifax, Nova Scotia.

M -Tec’s tipping fee of $55 per tonne will have the added benefit of creating valuable road construction materials containing 18-22% asphalt and alternative fuels containing about 28 GJ per tonne (12,000 BTU per pound).

Experience in Nova Scotia shows that using M-Tec’s refined product reduces the demand for virgin asphalt in pavement while maintaining good pavement performance. Pavement production cost savings can reach up to $2.50 per tonne of asphalt pavement.

EcoWaste is pleased to announce that we are testing Asphalt Shingle Recycling at our facility. We will be accepting ‘clean’ loads of shingle tear-offs free of wood, metal siding, and plastics at a discounted rate. Contaminated loads will be charged regular disposal rates.

Since June 2009 we have been diverting loads of asphalt shingles for processing in a grinder built specifically for this purpose. This process takes shingles from full size to ½” minus aggregate (99% is 3/8” minus) that can be reused in asphalt paving mixes, when the product contains almost no wood, metal, or other unwanted materials. We encourage roofers to deliver clean loads, which leads to a clean product.

Across the border, King County Solid Waste Division is partnering with the Road Services Division, which has contracted with Tacoma-based paving contractor and shingle recycler, Woodworth & Company, to overlay a 2-mile stretch of road near Enumclaw, Washington. The road section was paved in September 2009 with two HMA mixes - one containing 15% recycled asphalt pavement (RAP), and the other containing 15% RAP and 3% recycled asphalt shingles (RAS) for tear-off roofing project. The Washington State Department of Transportation provided mix designs for HMA mix containing RAS. The project report is expected to be completed in January, 2010.
