Nondestructive Evaluation of MoDOT Bridge Decks - Pilot Study

项目名称：	Nondestructive Evaluation of MoDOT Bridge Decks - Pilot Study
摘要：	Data required to assess the structural condition of bridge decks can be collected using various methods such as visual examination, surface sounding, removal and evaluation of samples, and noninvasive imaging. Nondestructive testing (NDT) techniques, in particular, enable rapid and comprehensive data collection. The optimal utilization of appropriate NDT technologies can result in more accurate bridge deck assessments and significantly reduced costs. The overarching goal of this pilot study is to demonstrate proof of concept that advanced nondestructive testing/evaluation (NDT/NDE) techniques can be rapidly, effectively, and economically implemented as part of the Missouri Department of Transportation (MoDOT) bridge deck surveys to improve the overall quality and cost of bridge deck evaluation. The accuracy and appropriateness of selected existing and emerging technologies will be evaluated using field data acquired from the entire suite of bridge decks investigated in this study. Technologies investigated will include two types of ground penetrating radar (GPR) and a portable seismic property analyzer (PSPA). Results of this pilot study will be used to evaluate the feasibility of a large scale, long-term program (multi-year, routine basis) that incorporates NDE techniques into MoDOT bridge deck surveys for the purpose of reducing cost on assessment and maintenance of bridge decks. The results will enable better, more cost-effective decisions of when to repair, strengthen, or replace the deteriorated bridge deck. The proposed research will also serve to educate and train multi-disciplinary students and future engineers in these technologies.
