Abstract

This digest summarizes the results of research conducted as a follow-up to NCHRP Project 24-28, “LRFD Metal Loss and Service-Life Strength Reduction Factors for Metal Reinforcements in Geotechnical Applications.” (The full text of the project final report is available for download at http://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=727) NCHRP Project 24-28 assessed and improved models for corrosion potential, metal loss, and service life of metal-reinforced systems used in retaining walls, and highway cuts and fills. The project compiled a performance database for earth reinforcements that describes the existing conditions and measured corrosion rates of in-service reinforcements at approximately 170 sites across the United States and Europe. Data were obtained from reinforcement types typical of mechanically stabilized earth systems (MSES) as well as installations of rock bolts and ground anchors. These data were used to identify and group trends related to the character of the fill or in-situ earth materials, reinforcement type, and various site conditions.
