Aesthetic-based conflict in highway planning: Federal Highway Administration putting planners at risk
The Department of Transportation's Federal Highway Administration aesthetic-based legislation, policies, regulations, guidelines, and procedures as well as their implementation are not only inadequate and inappropriate for avoiding conflict, but they actually contribute to conflict. The exploration …

New developments in steel reinforcement protection from corrosion
Due to life-cycle costs considerations, the Federal Highway Administration has required that all their new bridge structures have a service life of more than 75 years. The practical use of adequate concrete cover, low water/cement ratio, and corrosion inhibitors and admixtures are not enough to …
