State of Practice for Specifying and Repairing Mechanically Stabilized Earth Walls

Wisconsin Department of Transportation (WisDOT) frequently uses Mechanically Stabilized Earth (MSE) walls due to cost-effectiveness and ability to tolerate movements during their service life. WisDOT has observed excessive deformation or wall-facing damage due to deterioration or vehicular impacts. Research into durability of MSE wall reinforcements and best practices to ensure their longevity would be beneficial. This research will evaluate allowable limits for MSE wall settlements and out-of-plane movements and investigate repair/remediation methods when those limits are exceeded, with or without signs of distress. The research will investigate repair solution to address compromised wall facings.
