Development of Prefabricated Bridge Railings

Many organizations are promoting and utilizing Accelerated Bridge Construction (ABC) practices to reduce traffic impacts and to reduce societal costs. One of the most common means to achieve ABC is to utilize prefabricated elements which are brought together, on-site, to construct the in-place bridge. The purpose of this research is to begin the process of developing crash-tested prefabricated concrete bridge railings that have durable anchorage details. The developed prefabricated bridge railings must be attached to a bridge superstructure with durable connections that satisfy the Manual for Assessing Safety Hardware (MASH) 2009 Specification. Needed anchorage systems include details that connect the prefabricated bridge railing to the bridge deck and details that connect one prefabricated bridge railing to an adjacent prefabricated bridge railing. The end products of this research will be crash-tested prefabricated bridge railings with recommended durable anchorage systems and details that meet design test level TL-4 in accordance with MASH and Load and Resistance Factor Design (LRFD) Bridge Design Specifications.
