Also used for temporary structures, which is especially cost-effective and time-efficient for temporary detours necessary for highway reconstruction projects.Construction Methods:Construction is well established, using placement of reinforcement followed with compaction of the fill over the reinforcement.Additional Information:A variety of facings for MSE walls are currently available and in use. Bridges may be supported directly on top of the MSEW(via a spread footing) or on deep foundation elements that pass through the reinforced soil mass. Cost-effective alternatives for most applications where reinforced concrete or gravity type walls have traditionally been used to retain soil. Recent related developments in reinforced soil applications such as modular block/geosynthetics walls and Tecco mesh/ shotcrete facing systems are included with the MSEW technology.Geologic Applicability: Particularly suited to economical construction in fill embankments, steep-sided terrain, in ground subject to slope instability or in areas where foundation soils are poor. Furthermore, MSE walls are more flexible than conventional retaining walls and, therefore, are suitable for sites with poor foundations and seismically active areas. MSE walls are cost effective compared to conventional concrete cantilever retaining wall systems, especially for walls in fill embankment cross sections, and should be considered when selecting a retaining wall type. Reinforced soil structures are generally classified as a wall when the face batter is equal to or greater than 70 degrees from horizontal, and are classified as Reinforced Soil Slopes (RSS) when the face batter is shallower. The general acceptance, expiration of patents, and widespread use of this type of construction has led to generically naming retaining wall construction as Mechanically Stabilized Earth Walls (MSEW). Design and Construction of Mechanically Stabilized Earth Walls and Reinforced Soil Slopes, FHWA NHI-10-024 Vol I and NHI-10-025 Vol IBasic FunctionMechanically Stabilized Earth Wall Systems (MSE walls) use reinforced soil to create a composite retaining wall system which can be used where change in grade is necessary.Advantages: Simple and rapid construction procedures Reduced right of way Cost effective compared to traditional walls Aesthetically pleasing appearanceGeneral Description:Reinforced soil consists of tensile reinforcements added to soil to form a stronger composite material mass.
