The 18th meeting of the Sustainable Pavements Technical Working Group (SPTWG) gave stakeholders the opportunity stakeholders to provide technical input on sustainability and environmental aspects of pavements and pavement materials. The meeting, which began with opening remarks by Heather Dyllla, FHWA Sustainability Program Manager, also created a forum to share information and discuss resources.

Held in Detroit last week, the two-day meeting covered a wide variety of topics, including streets and urban sustainability, innovations by the Michigan DOT, and product category rules (PCRs) and environmental product declarations (EPDs). The meeting also addressed life cycle analysis data issues and included a demonstration of the FHWA’s LCA tool.

Participants also heard a presentation on pavement vehicle interaction (PVI) by Karim Chatti, Michigan State University; Imad Al-Qadi, University of Illinois; and Jeremy Gregory, of the Massachusetts Institute of Technology (and CS Hub). A PVI panel discussion followed and addressed timely questions about PVI, including gaps in modeling, as well as implementation steps for using PVI models in the short term. Technical updates presented by the FHWA included an update on the FHWA PVI study and sustainable pavement studies. 

Facilitating and participating in the discussions were Kurt Smith and Prashant Ram of ApTech, an ACPA member. Leif Wathne participated in the meeting, representing ACPA and the concrete pavement industry’s perspectives.
