Webinar Recording: Bridge Deck Preservation Portal, Phase 1

 

View a recording of WJE's recent webinar, Bridge Deck Preservation Portal, Phase 1.

Preservation actions performed on bridges or bridge elements extend their service life. The transportation networks are extensive and funds are limited. This requires agencies to find cost-effective strategies that keep as many existing bridges in good and fair condition. As such, the Federal Highway Administration (FHWA) and Iowa Department of Transportation (DOT) funded a research study to develop a report demonstrating proof of concept and a future Request for Proposal to develop a web- or PC-based bridge deck preservation portal.

In this one-hour webinar, Dr. Mohamed ElBatanouny of WJE, Mr. James Nelson of Iowa DOT, and Mr. Raj Ailaney of FHWA discuss the completed Phase 1 of this research aimed to develop a framework for a bridge deck preservation tool that can help engineers at state and local departments of transportation choose the optimum preservation action for a given bridge deck.

By the end of the presentation, you will:

  • Learn about the proposed tool and its five modules
  • Review available maintenance actions for concrete, steel, and timber bridge decks, including service life and cost information
  • Assess the innovative probabilistic algorithm developed to provide estimates for service life extension associated with the different maintenance actions 
  • Evaluate the results of three example bridges from Oregon, Iowa, and North Carolina analyzed using a preliminary MATLAB tool that was developed to test the logic proposed in this effort.
