Quantifying the Sustainable Benefits of Preserving Canada's Road Assets
The Ministry of Transportation of Ontario (MTO) has implemented numerous innovative pavement preservation strategies in recent years to maximize cost savings in repair operations and extend pavement life in a sustainable manner. These strategies are considered sustainable as they improve pavement quality and durability, and extend pavement service life, while reducing energy consumption and green house gas (GHG) emissions. This paper outlines the various flexible pavement preservation treatments utilized by MTO to achieve sustainability including micro-surfacing, chip seal, ultra-thin bonded friction course, fiber modified chip seal, and hot in-place recycling (HIR). Pavement preservation sustainability is quantified in a case study using the PaLATE software by comparing the energy consumption and GHG emissions generated for various flexible pavement preservation strategies, against a conventional rehabilitation treatment on a life cycle basis. The results indicate that these innovative pavement preservation strategies significantly reduce energy use and GHG emissions when compared to traditional treatments. The paper quantifies the sustainable benefits of innovative flexible pavement preservation treatments in terms of energy and material savings and GHG emission reductions. An innovative environmental rating system to promote sustainable preservation of road assets is also discuss
