The Mechanically Stabilized Earth (MSE) wall was constructed by Muskogee Bridge Company as a part of project IM-NHIY-44-2(349)231 on 1-44 in Tulsa. The main objective of the Strengthened Earth Wall project was to evaluate the constructability of the structure as compared to other MSE walls currently used in Oklahoma. A strong secondary consideration was cost analysis. The wall was constructed in a timely fashion and no problems with performance are anticipated. Some advantages included; speed of construction, larger panels, and thicker backfill lifts. It is recommended that Strengthened Earth Wall be included in ODOT specifications and its use allowed where competitive bidding makes the cost comparable with other MSE structures.29 pages1,466,733 bytesapplication.pdfTechnical ReportRetaining wallMSEstrengthened earth wall
