Earlier this year, researchers completed the first phase of an effort to help refine Iowa DOT’s current bridge management decision-making program. Focusing on bridge decks, the proposed framework provides a ranked list of alternative maintenance strategies for individual bridges, approximating cost, service life, and risk as part of the evaluation. Next steps would be to fully develop the framework into a web- or PC-based tool.

The Vermont Agency of Transportation recently evaluated the performance of a high-friction bridge deck overlay system that also functions as a waterproofing membrane. The quick-curing overlay consists of an aggregate chip seal affixed with a synthetic polymer epoxy. Five years after application on a low-volume bridge, annual site visits and structures inspections have shown the bridge and overlay to be in good condition, and the system has provided good skid resistance and waterproofing.
