1.1 ,Mechanically stabilized earth walls (MSEW) covered in this standard practice are engineered earth retaining structures comprised of pre-fabricated wall facing elements and select backfill reinforced with inextensible steel elements. This practice covers procedures and components for the construction of MSEW including soil reinforcement, connections to panels, and selection and placement of granular backfill. Such walls may have a segmental precast concrete (SPC) facing or a flexible wire facing. This standard practice does not address the design of MSEW.
