The Building Better Roads Working Group includes two subcommittees that take a closer look at the topics the group is most interested in. Each subcommittee works on 2-3 topics at time with the end goal of producing a “deliverable”. Examples of past deliverables include guidance documents, fact sheets, pilot studies, training workshops and product demonstrations.
