Extensive exam

In order to comply with the Moving Ahead for Progress in the 21st Century Act (MAP-21) requirements, bridge inspections are going to new lengths, as explained in this article. The Federal Highway Administration (FHWA) is implementing policies that will incorporate risk-and-performance-based management of bridges in the United States. For example, for the National Highway System (NHS), bridges are required to quantify, for example, how much of the deck is in which one of four condition states. This way, the bridge is being broken into measurable quantities and pieces. As a result, the process is less subjective and more consistent, specific and quantifiable. Inspectors are being taught to recognize the potential consequences and seriousness of what they see, with the most common types of deterioration of bridges being corrosion and stress-related cracking.
