Goldset(c): Application of a Sustainability Decision Support Tool to the Roof Asphalt Shingles Recycling Project of Metro Vancouver

Asphalt shingles constitute approximately 2% of the total waste currently disposed in the Metro Vancouver region, which corresponds to between 60,000 and 80,000 metric tonnes per year. Developing alternative uses for asphalt shingles would help the Metro Vancouver region achieve the Zero Waste Challenge and the Sustainable Region Initiative's goal of 70% waste diversion by 2015. Metro Vancouver (MV) has mandated Golder Associates Ltd (Golder) to conduct a feasibility study for the use of reclaimed asphalt shingles (RAS) in road construction. In the last decade, several trials have been performed to use RAS as an input for pavement mix across North America. MV has expressed an interest in performing an integrated sustainability assessment for economic, social, environmental as well as technical aspects of using processed RAS in road construction. This assessment is conducted using the Golder Sustainable Evaluation Tool (GoldSET), an innovative, simple Multi-Criteria Analysis (MCA) tool based on the principles of sustainable development. GoldSET has been customized to compare different options of asphalt mix: pavement containing only virgin asphalt cement, pavement containing recycled asphalt pavement (RAP), and pavement containing different ratios of RAS and RAP.
