Samenvatting
The Technology Implementation Group of the American Association of State Highway and Transportation Officials identifies high-payoff, ready-to-use technologies that meet widespread transportation system needs and develops plans to accelerate their deployment with states as the champions. The group initially has chosen six priority technologies likely to yield significant economic or qualitative benefits: prefabricated bridge elements; intelligent transportation systems for work zones; accelerated construction methods; air void analyzers for concrete; ground-penetrating radar for asphalt; and global positioning systems for surveying. This article is a progress report on these six technologies.
