Abstract

Interest in the use of composite materials is increasing due to the urgent need to improve and harden our infrastructure, combined with the pending infrastructure bill. Pilot and prototype efforts demonstrate the advantages of factory-produced rapidly-installed lightweight composite bridge decks. The composite technology and the fabrication method facilitate structural health monitoring using low-cost embedded sensors and fiber optics. This session will detail installation of the first composite bridge deck in Tennessee. Results of the project will be presented, with a focus on the ongoing structural health monitoring, embedded sensors, and the outlook for standard installation.
