Project description

This research project aims to (1) benchmark greenhouse gas emissions from the construction of WSDOT’s projects based on existing specifications and sourcing practices; (2) identify needs for additional testing and research by WSDOT’s HQ Materials Laboratory based on current gaps related to decarbonization; and (3) provide recommendations on easily-implementable, cost-effective strategies for reducing WSDOT’s carbon footprint where strategies and testing already exist. The research scope will include concrete, asphalt, and steel products on the pre-approved products and vetting process for WSDOT’s qualified product list (QPL). This research will provide a first step in identifying opportunities for WSDOT to reduce greenhouse gas emissions related to construction by focusing on opportunities related to standard specifications and practices that can be implemented across WSDOT projects.
