A structural barrier and energy absorbing device comprises a plurality of structural elements. 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.

A kerb barrier includes: a first barrier member having a length, the first barrier defining a cavity; and a second barrier member in the cavity of the first barrier that extends substantially along the length of the first barrier member, wherein a base of the second barrier member is fixable to a base of the first barrier member, wherein, upon side impact, a region of the first barrier member is configured to bend relative to the second barrier member about a first bending point defined by the first barrier member, wherein the first barrier member is configured to act on the second barrier member such that the region of the first barrier member and a region of the second barrier member are configured to bend about a second bending point defined by the second barrier member, wherein the second bending point is spaced apart from the first bending point.

A barrier for a roadway (e.g., a highway, bridge, or other road), which can be used to manage vehicular traffic, such as to establish lanes, protect motorists and other people (e.g., pedestrians, constructions workers, etc) against crashes or other impacts, and/or other purposes, and which may be configured to enhance its use and performance, such as by better protecting the motorists and others when impacted by vehicles (e.g., reducing deflection by deflecting less or substantially not deflecting; mitigating risks of “catapulting” or “vaulting” of vehicles; and/or otherwise improving protection provided by the barrier), facilitating transportation, installation and/or transfer of the barrier at the roadway, and/or enhancing other aspects of the barrier.

A resin-based barrier comprises a body having a skin of fiber-reinforced resin. The body includes a top, a bottom, a front end, and a back end. A vertical shear web runs between the top and the bottom and is substantially perpendicular to the top and the bottom. Moreover, spaces between the vertical webbing and between the longitudinal webbing are filled with a high-density closed-cell foam. The barrier may be used as a temporary traffic barrier during road construction.

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.

A kerb barrier includes: a first barrier member having a length, the first barrier defining a cavity; and a second barrier member in the cavity of the first barrier that extends substantially along the length of the first barrier member, wherein a base of the second barrier member is fixable to a base of the first barrier member, wherein, upon side impact, a region of the first barrier member is configured to bend relative to the second barrier member about a first bending point defined by the first barrier member, wherein the first barrier member is configured to act on the second barrier member such that the region of the first barrier member and a region of the second barrier member are configured to bend about a second bending point defined by the second barrier member, wherein the second bending point is spaced apart from the first bending point.

A concrete-based composite material including iron rich particles is characterized by an iron content greater than 17% by weight of the composite material, can include iron particles which are an iron by-product recovered from iron slag material, can include iron rich particles which have an iron content of at least 60% by weight of the iron rich particles, and/or can include iron particles having a particle size distribution in the range of about −⅜ inch to +60 mesh or in the range of about −20 mesh to about +60 mesh. The composite material can include ground granulated blast furnace slag as a portion of the cementitious component of the composite material. A method of forming a structural element from the composite material includes casting the structural element such that the structural element is characterized by a ballistic performance of Level 10 as defined by Underwriters Laboratories standard UL752.

An energy absorbing apparatus is provided and includes an outer shell having opposed ends, left and right side walls and a hollow core. The shell further includes a plurality of longitudinally spaced apart fold points positioned on the left and right side walls at a height which substantially corresponds to a center of gravity of a road vehicle where the fold points facilitate a controlled folding of the side walls and at least part of the shell, at or around, the fold points, during an end on impact.

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.
