A crash barrier system includes upper posts, box beams, upper tube profiles and barrier rails. The box beams are connected to the upper posts on a front side of the crash barrier system. The upper tube profiles are connected to the box beams. The barrier rails are fastened to the upper tube profiles. The upper posts are arranged axially parallel to one another at a uniform axial post spacing along the box beams. The upper tube profiles are arranged axially parallel to one another at a uniform axial tube spacing along the box beams. The post spacing differs from the tube spacing.

The guardrail, which may take the form of various types of guardrails, is noteworthy in that it includes an impact detector/indicator, for indicating the location of the guardrail involved in an impact or accident and also for notifying the accident and the place where it occurred to a traffic control station or to public assistance personnel. The detector/indicator includes a convex protective plate (2) attached to the front of the guardrail (1) with which it is used, said plate (2) protecting a connection box (3) and a tube (4) so as together to create a means for detecting and communicating the impact that occurred, also having an indicator light (5) for flagging up the impact, said indicator (5) being positioned on a support plate (6) secured above the protective plate (2).

A system for illuminating a carriageway in a case of fog includes a road safety barrier arranged along the carriageway, at least one fog density detecting device arranged along the road safety barrier, and a plurality of light sources borne by the road safety barrier, distributed along the road safety barrier, and oriented for each to emit a light beam having a direction that is transversal to an extension axis of the road safety barrier so as to illuminate signage on the carriageway. A control unit that is connected to the light sources and to the fog density detecting device is configured to activate the light sources when the fog density detecting device detects a fog density value of above a threshold value.

A tree-planting structure device includes a securing net, an anchor, a plurality of stacking pouches and hooks. The securing net is formed in a size capable of covering a part of a guard, the ground, or a building outer wall and having an arrangement of a plurality of meshes. The anchor is coupled to the guard, the ground, or the building outer wall in order to fix a position of the securing net. The plurality of stacking pouches includes sacks coupled to the meshes for forming the securing net and respectively having plant growing soil contained therein. The stacking pouches are stacked while coming in contact with the securing net. The hooks include members for coupling the stacking pouches to the meshes of the securing net.

The upper tube profiles are connected to the box beams. The barrier rails are fastened to the upper tube profiles. The upper posts are arranged axially parallel to one another at a uniform axial post spacing along the box beams. The upper tube profiles are arranged axially parallel to one another at a uniform axial tube spacing along the box beams. The post spacing differs from the tube spacing.

A sustainable article including a waste material and a binder is provided. The binder is mixed with the waste material and configured to bind the waste material to form the sustainable article. The binder may include a catalyst configured to enable the binder to bind the waste material to form the sustainable article. The sustainable article further includes a reinforcement system.
