Abstract:The Federal Highway Administration has worked cooperatively with the
American Association of State Highway and Transportation Officials in
developing and updating the pavement design guide. The current guide is
slated to be updated by the year 2002 to better reflect the changing priority
of rehabilitating the nation’s highways rather than building new ones. In
contrast to the current guide that many transportation experts believe is
outdated, the new guide is expected to incorporate the use of analytical
methods to predict pavement performance under various loading and
climatic conditions. Sponsors believe that “a new design approach will
more realistically characterize existing highway pavements and improve
the reliability of designs.”
