Welcome to the SCOR/RAC Website

This website is intended as a resource for the American Association of State Highway and Transportation Officials (AASHTO) Standing Committee on Research (SCOR) and its Research Advisory Committee (RAC).

The site has two main purposes:

  • For new RAC and SCOR members, the site serves as an orientation tool, providing background information and quickly showing new members how to become full participants in committee activities.
  • For all members, the site is a reference tool that documents operational procedures, membership rosters, coming events, links to other sites, and current committee activities.
