An apparatus includes a base having a length in a first direction, a height in a second direction different from the first direction, and a depth in a third direction different from the first direction and the second direction. The base includes at least one sidewall having an outer surface, an inner surface, and an edge defining an open end of a cavity within the base. The base also includes a plurality of ribs extending from the inner surface of the at least one sidewall toward the open end of the cavity. The ribs of the plurality of ribs are separated from one another along the first direction. The base further includes at least one tube extending from the inner surface of the at least one sidewall toward the open end of the cavity. The apparatus also includes at least one plaque removably attached to the outer surface of base.

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of an impacting vehicle and ramping of the impacting vehicle and stabilizing structure including a midnose structure resisting relative rotation between crash cushion elements in both vertical and lateral planes during vehicle impact.

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of an impacting vehicle and ramping of the impacting vehicle and stabilizing structure resisting relative rotation between the crash cushion elements in both vertical and lateral planes during vehicle impact. A transition weldment is employed to connect the anchorless crash cushion apparatus to a rigid hazard object.

A structural barrier and energy absorbing device comprising a plurality of structural elements is provided. The structural element alone or in a plurality may serve as a traversal impediment or energy absorbing device, such as a pedestrian barrier, vehicular barrier, anti-tank obstacle, ballistic barrier, or the like. The structural element may be a tetrapod such that it comprises an element body having four extension portions that extend outwardly from the interior center to a distal end, such that the structural element maintains an identical orientation and a low center of gravity in each of four resting positions. The structural element may be a solid-state structural element comprised of a particular material or a portable and collapsible structural element wherein the element body comprises an outer skin defining an interior void space, such that during set-up or installation the interior void space may be filled with a filler substance onsite.

Molded plastic barrier segments, typically water or sand-ballasted, are engineered to be attached together, end-to-end, in a barrier array, with innovative features which result in low rotation between attached barrier segments. Such a low rotation barrier array will, upon impact by a vehicle, act as a re-directive barrier, rather than a capturing barrier, which is an important safety feature in some crash scenarios, particularly with respect to more recent safety specifications required by many governmental highway agencies.

The present invention concerns a security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering and wherein the at least one mineral wool element is adapted for being filled with a liquid. The invention further comprises a method of manufacturing such security barrier and a method of preparing the security barrier for providing protection in a public space.

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.

A highway sound barrier system that uses a plurality of foam panels that are joined with an upright member assembly. The foam panels use a foam core and exterior weather protection compounds allowing the system to dramatically reduce transportation, handling and installation costs while increasing the lifecycle of the barrier system and reducing long term maintenance requirements. Moreover, the foam panels include rotatable joints allowing the wall to be easily adjusted to facilitate various landscape parameters and provide for rapid construction.

A barrier element for bounding a carriageway including an elongated casing, having two opposing longitudinal side walls and an upper wall joining the two side walls; and at least one casing support structure located in the elongate casing and connecting to both the side walls. Additionally, a support structure for use in a barrier element.

A stackable, portable, traffic barrier having a molded elongated body with a generally extruded triangular shape having a longitudinal axis; a separable base; a top; a first pair of opposing sides disposed between the top and the base; a second pair of arcuate opposing sides disposed between the top and the base; a plurality of vertically disposed fillable cavities disposed through the top of the body; and a plurality of caps, where each of the caps has a cross sectional shape suitable for functionally engaging a corresponding cavity.
