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 expansion troughs to accommodate hardware 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 plates attach the footers of adjacent segments to one another.

A method of slip forming a concrete structure can include using a first slip form mold that travels along a path to form a portion of a concrete structure by delivering a first flow of concrete into the first mold through a first hopper. The first hopper can be configured to receive the first flow of concrete. The portion of the concrete structure can be modified using a second slip form mold different from the first mold by advancing the second mold along the concrete structure and, while advancing the second mold, delivering a second flow of concrete into the second mold through a second hopper that is configured to receive the second flow of concrete.

A traffic barrier and soundwall system is disclosed having wide-flanged [or H-posts] vertical posts oriented with a flange facing a roadway. Traffic barriers are located between them. The barriers have recesses at the intersection of their backs and ends. An angle bracket is positioned in the recess to separate the post from the barrier. A U-shaped strap has a base and a pair of arms extending from the base. Traffic barriers are positioned against the posts so that the angle brackets in the recesses are adjacent to the road-facing flange of the post. A strap fastener connects an arm of the strap to the recess of each of the adjacent traffic barriers. In this way, the base of the strap surrounds the rearward-facing flange of the post to secure the traffic barriers to the post. Sound barrier panels are located on the top of the traffic barriers, secured between the webs of the neighboring posts.

A traffic barrier and soundwall system is disclosed having wide-flanged [or h-posts] vertical posts oriented with a flange facing a roadway. Traffic barriers are located between them. The barriers have recesses at the intersection of their backs and ends. Sound panels are stacked on top of the traffic barriers. A crash panel is located between the vertical posts, above one or more sound panels. The crash panels have recesses at the intersection of their backs and ends. Additional sound panels are stacked above the crash panels. An angle bracket is located in the recess. U-shaped connectors connect the recesses of adjacent traffic barriers together around a post. U-shaped connectors connect the recesses of adjacent crash panels together around a post, and above the traffic barriers and sound panels to achieve a MASH TL-4 crash test rating.

A road barrier transfer machine includes an improved capstan control system that reduces unwanted migration of road barrier spans without requiring inaccurate visual observations and reliance on outdated scripts. The barrier transfer machine includes a moveable chassis, an entry snout, an exit snout, a conveyor system, a capstan system, and the capstan control system. The capstan control system automatically operates the capstan system or provides instructions to an operator of the machine to maintain the tension and compression of a road barrier span within desired ranges to reduce unwanted migration of the span.

A traffic safety device placement apparatus that permits the placement of traffic safety devices with reduced labor requirements and increased safety measures. Traffic safety devices can be moved into or out of the roadway without the need for anyone being exposed to traffic and can be placed much more quickly than previously known devices.

Certain exemplary embodiments can provide a system, machine, device, and/or manufacture comprising a traffic separating median barrier comprising: a barrier body having a substantially uniform cross section along a longitudinally extending direction, said barrier body defining a body length extending along said longitudinally extending direction, a body width orthogonal to said body length, and a body height orthogonal to said body length and said body width, said barrier body terminating in a first barrier end region and a second barrier end region, said first barrier end region comprising a female interlocking structure attached to said barrier body, said second barrier end region comprising a male interlocking structure attached to said barrier body, said female interlocking structure adapted to interlock with said male interlocking structure.

The invention relates to a reinforcing element for a concrete barrier-wall element, which concrete barrier-wall element has a repelling profile on at least one longitudinal side, wherein the reinforcing element has longitudinal reinforcing bars and has bows, which extend transversely to the longitudinal reinforcing bars and are connected to the longitudinal reinforcing bars. According to the invention, the reinforcing element has at least one first region and the first region largely has the repelling profile. The invention further relates to a method for producing a concrete barrier-wall element having a repelling profile on at least one longitudinal side.

A traffic barrier system of series connectable barriers, each barrier having a body with a skirt section, an intermediate section comprising a lower portion, a central portion, and an upper portion, and a head section extending above the intermediate section. The skirt section and lower portion have positive slopes. The upper portion and head section have negative slopes. A vertical end channel is formed on each of the opposite first and second ends. A lower tension bar is cast in the skirt section and an upper tension bar is cast in the head section. Within the body of the barrier, the tension bars are articulated in relation to each other. The tension bars have tabs extending out of the body for overlapping pivotal connection to an adjacent barrier.

Disclosed is a protective arrangement having elements which essentially consist of concrete and are connected to one another via detachable couplings. The elements of the protective arrangement are arranged in the form of a closed frame.
