A barrier system is used to direct and block a travel path of pedestrians and vehicles. The barriers may be shaped substantially as a truncated pyramid with a base surface and planar sides extending from the edges of the base surface to a top portion, where the cross-sectional area of the base surface is larger than the cross-sectional area of the top portion. The angles of inclination between the planar sides and the interior of the base surface are acute angles. The bollard can be cast from heavy dense materials. The bollard includes at least two overhanging lips on the planar sides of the barrier between the base surface and the top portion. The configurations of the bollards provide improved placement, such as with cranes, hand carts, and other devices. Molds to cast the barriers and hand carts to move the barriers are also disclosed.

The invention provides a security barrier section (10) which has first (12) and second (14) barrier islands and cables (28, 30) there between. Each barrier island comprises a cast concrete block (16) having a front face and a rear face and a spring steel post (22) extending upwardly from a top face of the cast concrete block at a location between the front face and the rear face. An attachment means (26) is located on, or extending from, at least one of the front face and the rear face. At least one first cable (28) extends between the spring steel posts (22) of said the first (12) and second (14) barrier islands and is attached thereto by cable attachments. At least one second cable (30) extends between the attachment means (26) of said first (12) and second (14) barrier islands and is also attached thereto by cable attachments. The cable attachments are configured to allow said cable to slip in said cable attachment under loading.

An erectable barrier unit as well as a barricade made of a plurality of units are disclosed. The erectable barrier unit comprises a base and at least one movable hurdle connected to the base wherein the movable hurdle can instantly erect from a resting position in which the hurdle is adjacent to the base to an erected position in which a predetermined angle is formed between the hurdle and the base.

The invention relates to a composition having plasma-treated recycled steel fibers within the matrix.

An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.
