The Federal Highway Administration started a focused program of structural research centered around the development and use of high-performance materials -- materials that are stronger, more durable, and offer the potential for lower life-cycle costs. High-performance materials offer substantial hope for better systems that last significantly longer. While research laboratories are still exploring these materials, some are already in use. The Texas Department of Transportation has initiated two high-performance concrete bridge projects. And in California and other states, composite materials are being used for the repair and retrofit of bridges.
