Nondestructive Testing to Identify Concrete Bridge Deck Deterioration. Strategic Highway Research Program.

摘要

Society is more dependent than ever on transportation for its economic vitality and quality of life. Highways are the foremost of all transportation modes. As our dependency on infrastructure is growing, the engineered components of transportation infrastructure are aging, deteriorating, and exhausting their capacity to meet the ever-expanding operational demands. Ensuring operational and structural safety and security of the transportation infrastructure represents a paramount task that requires a fundamental change in the way we plan, design, build, and operate our transportation infrastructure. This task can only be effectively addressed through broad political and public support and the integration of talents in diverse areas. These areas are financing, planning, asset management, design, construction, materials, inspection, and so forth. With this broad challenge identified, the second Strategic Highway Research Program (SHRP 2) has gathered and deployed the intellectual, experiential, and financial resources necessary to answer the questions about highway safety, renewal, travel-time reliability, and capacity. Methods must be identified to rapidly rebuild the infrastructure system with long-lasting facilities. Renewal of our highway system has become especially challenging because much of the aging infrastructure is in heavily congested highway corridors. Therefore, minimizing traffic disruptions during highway renewal projects is a paramount goal. In addition, developing and implementing the means for the rapid and accurate inspection and performance monitoring of highways is of the essence, in order for the safety and durability experiences of the past to be avoided.
