A roadside barrier which has underlying concrete support blocks, a mesh fence, optionally including overlying transparent sheet material, which is erected on the blocks, and a deterrent, sloping mesh-material, surface, which hinders human access, at a base of the fence on the support blocks.

A safety barrier includes: a body installed on a road; a steel plate portion placed between the body and the road; and an anchor portion passing through the steel plate portion and having an upper part buried in the body and a lower part buried in the road, wherein a first space in which a middle part of the anchor portion other than the upper part and the lower part is placed, is formed between the body and the road, and when an impact is applied to the body, the body is moved while accompanying bending deformation of the middle part in the first space so that the impact is absorbed, and after bending deformation of the middle part occurs, the steel plate portion breaks the anchor portion to implement further movement of the body caused by the impact so that the impact is dispersed.

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that reduces unwanted migration of road barrier spans without requiring inaccurate visual observations and reliance on outdated scripts.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 modular cover panel including two or more cover panels that cover a parapet or barrier along a roadway. Multiple cover segments may overlap one another to form the modular cover panel and each cover panel is individually hung or suspended by brackets affixed to the parapet. Each cover segment has one more surfaces intersecting with other to cover the parapet and a top surface that overhangs a top surface of the parapet. A cable may be disposed through a slot of a hanging bracket and a pin may secure the cable thereby providing a mechanical attachment to the assembly.

The present disclosure relates to a low-profile barrier including a plurality of segments continuously arranged in the longitudinal direction and a connecting member installed in a connection portion, the connection portion between the segments configured to bend in the horizontal direction in order to effectively absorb impacts in the event of a vehicle collision, thereby ensuring safety of vehicles and vehicle occupants, and a method for constructing the same.

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.

Various embodiments for a median barrier finishing machine are described. A median barrier finishing machine may include a housing configured to encapsulate at least a portion of a median barrier, where the housing comprises a first vertical wall, a second vertical wall, and a horizontal wall. The median barrier finishing machine may include at least one adjustable member configured to couple the housing to the vehicle and retain the housing a predetermined distance relative to the vehicle while the vehicle is in motion. Further, the median barrier finishing machine may include at least one finishing device disposed within the housing, where the at least one finishing device is configured to contact a surface of a median barrier at least partially positioned within the housing and treat the surface as the vehicle moves the housing along a length of the median barrier.

Road safety barrier comprising: concrete bottom parts (1); concrete top parts (2) coupled on the bottom parts (1), and attaching means (3, 31) of the successive top parts (2) at their opposite ends. The bottom parts (1) have an upper surface provided with a longitudinal channel (11) for coupling in the longitudinal direction and with the possibility of limited vertical displacement of a longitudinal extension (21) protruding from a lower surface of the top parts (2); the channel (11) and the extension (21) have similar cross-sections and dimensions calculated so that the top part performs a lateral rotation of a determined amplitude, in the event of a vehicle impact, and absorbs a significant part of its kinetic energy.

A barrier transition framework such as for use as a bridge transition, is disclosed for connection to a concrete anchor at an entrance, comprising a tubular upper transition chord having first and second beveled ends, and a tubular lower transition chord having first and second beveled ends. The first beveled ends of each of the upper and lower chords are welded to an approach deflector. The second beveled ends of each of the upper and lower chords are welded to an anchorage plate. A transition assembly is formed by connecting thrie-beams to the road-side of the transition framework. A thrie-beam may also be connected to the field-side of the transition framework. The disclosed transition framework provides a preassembled solid four bar structure with exceptional resistance to deflection in both the vertical and horizontal planes, that spans a greater distance than convention transitions.

A vehicle barrier system is provided. The system includes a barrier structure integrally connected to a moment slab. The barrier structure includes a front curb section connected to two side curb sections that each extend at an angle from the front curb section in a direction toward the moment slab. The front and side curb sections are formed by a casing into which concrete is poured. The barrier structure and moment slab are cast-in-place concrete structures. The barrier structure may be installed on top of an elevated structure so that a vehicle may back up to the front curb section and dump material from the elevated structure.
