摘要：	This article describes the Federal Highway Administration's (FHWA's) program of research and development in nondestructive evaluation of the nation's bridges. The program is currently focusing on developing technologies to address a wide range of problems. One focus area is the detection and evaluation of fatigue cracks in steel highway bridges. Another area is developing technologies for the rapid and quantitative evaluation of reinforced concrete bridge decks covered with bituminous concrete. This article summarizes FHWA's current research and development program, highlighting the program objectives, background, advanced bridge deck inspection technology, advanced-bridge-testing and health-monitoring projects, advanced fatigue-crack detection and evaluation projects, advanced corrosion detection and evaluation projects, and other advanced nondestructive evaluation projects. The program of research and development is helping to ensure the safety of the nation's bridges and providing more accurate and complete information about the condition of the nation's hghway bridges.
