7th Symposium on Pavement Surface Characteristics: SURF 2012
Browse by
The SURF 2012 symposium was held in Norfolk, VA from September 19 – 22, 2012. The event was organized by the World Road Association in partnership with the American Association of State Highway and Transportation Officials (AASHTO), the Transportation Research Board (TRB), the Federal Highway Administration (FHWA), the Virginia Center for Transportation Innovation and Research (VCTIR) and the Center for Sustainable Transportation Infrastructure (CSTI) at the Virginia Tech Transportation Institute (VTTI). The 2012 symposium focused on providing smooth, safe, quiet, and sustainable travel through innovative technologies. The symposium offered a unique platform to send a strong message about the importance of considering surface characteristics when building, renewing, and preserving roadways and airfields. SURF 2012 offered a unique opportunity for practitioners and researchers to share knowledge and expertise on this subject.
