Abstract: A traffic barrier soundwall includes a top portion attached to a bottom portion. The segments are reinforced by rebar, mesh, or combinations thereof. Dowel rods extend from the bottom edge of the top portion which fit into corresponding pipe sections along the top edge of the bottom portion. Grout is flowed into the pipe sections and an epoxy is applied along the length of the joining surfaces. The upper corners of each of the top and bottom portions have connection elements comprising troughs and PVC sleeves to attach the segments to adjacent segments. The bottom portion is generally T-shaped with a tapered cross-section. The footer of the bottom portion is installed under the ground level and connection elements comprising troughs to receive non-metal drop pins to attach the footers of adjacent segments to one another.

Grout is flowed into the pipe sections and an epoxy is applied along the length of the joining surfaces. The upper corners of each of the top and bottom portions have expansion troughs to accommodate hardware to attach the segments to adjacent segments.

The footer of the bottom portion is installed under the ground level and connection plates attach the footers of adjacent segments to one another.

Abstract: An improved mechanically stabilized earth retaining wall system comprising a plurality of base segments secured to a plurality of precast segments with dowel rods to provide an MSE wall system. Each precast base segment generally includes a T-shaped cross-section having the upright wall substantially perpendicular to the footer. The design of the footer of the base segment is configured to be disposed on a grade surface and self-support the precast base segment in an upright position when securing the precast segment to the precast base segment. In an alternative embodiment, the MSE wall system comprises a first MSE wall system secured to a second MSE wall system, with the second MSE wall system secured to an existing wall. The MSE wall system, in this exemplary embodiment, is configured to widen an existing elevated roadway built on top of traditional stabilized earth.
