Using Recycled Asphalt to Achieve Common Goals

 

This video describes the challenge of a main source of construction waste: used asphalt. The recycled asphalt paving pilot showcases a collaborative effort to demonstrate the opportunity of recycling reclaimed asphalt to both divert waste, and offset emissions. A strong leadership initiative across local government and industry, this project demonstrates the significant benefits of paving the way for circular economy principles within the built environment.

 

Piloting Recycled Asphalt to Showcase Opportunity

 

This video provides an overview of a pilot application of 40% RAP on a high volume arterial road in Richmond, BC. The project is believed to be the first such application on a public road in Canada. In the video, Richmond Mayor Malcolm Brodie invites cities across Canada to participate in creating solutions to managing asphalt waste through similar RAP applications.




Scoping Study:

Leading up to the design of the RAP pilot, research was undertaken to identify best practices for the specifications, design, production, testing and placement of RAP mixes. The Scoping Study includes a literature review and consultation with experts to better understand best practices used in other jurisdictions, as well as an analysis of market and supplier readiness, and environmental and technological considerations.

The Best Practices Checklist for RAP Projects was developed to identify critical categories to evaluate when developing recycled asphalt projects. The checklist is based on research findings from site visits, interviews, the RAP Scoping Study, extensive stakeholder consultation led by the City of Richmond, and a review of standards and specifications. It also takes into consideration the need to focus on improving quality and increasing industry involvement.

The RAP Technical Assessment Framework was developed to assess how pavement producers satisfy best practices found in other jurisdictions, as well as requirements identified by purchasers related to their own procurement targets. The framework is provided here as an open-source document that users can download and customize to meet their corporate objectives. In this way, criteria weighting can be adjusted according to the categories identified as priorities to each user.
