A modular block wall includes dry cast, unreinforced modular wall blocks with anchor type, or frictional type or composite type soil stabilizing elements recessed therein and attached thereto by vertical rods which also connect the blocks together. The soil stabilizing elements are positioned in counterbores or slots in the blocks and project into the compacted soil behind the courses of modular wall blocks.

The soil stabilizing elements are positioned in counterbores or slots in the blocks and project into the compacted soil behind the courses of modular wall blocks. Alternative stabilizing element designs may be used with the modular wall blocks and other types of facing elements in a mechanically stabilized earth structure.

Decreased weight, improved sound transmission loss, and maintained sound absorption and durability are all achieved by a highway barrier incorporating a new acoustic barrier panel. The panel remains of the type suitable for being forms, in combinations of multiple panels and multiple, earth-anchored or structure-mounted support posts, into sound barrier walls for use along highways, other rights of way, and the like. The invented acoustic barrier panel comprises a sandwich of slabs. The sandwich comprises a central slab, a first, outer slab sandwich alongside the central slab, and a second, outer slab sandwiched alongside the central slab, opposite the first outer slab. Uniquely, a first grout curtain is interposed between and joins the central slab and the first, outer slab, while a second grout curtain is interposed between and joins the central slab and the second, outer slab. As most preferred, all slabs constitute Durisol. TM. wood concrete.

An earthen work bulk form construction has a wire mesh facing and granular compactable fill with stabilizing members projecting horizontally into the fill from the front facing. The front facing is comprised of modular shaped panels which form a mosaic pattern that enables construction of the wall with non-adjacent panels serving to facilitate and support adjacent panels. Connection of the stabilizing members to the front panels is effected through a quick engagement and locking handle bar connector.
