A protective barrier includes a first end piece including a first opening and a first anchoring member for securing the first end piece to a surface, a second end piece including a second opening and a second anchoring member for securing the second end piece to the surface, a rail extending between the first end piece and the second end piece, the rail having a first end disposed in the first opening of the first end piece and a second end disposed in the second opening of the second end piece, and a cable system including a first fastener coupled to the first anchoring member, a second fastener coupled to the second anchoring member, and a cable having a first end attached to the first fastener and a second attached to the second fastener, the cable extending from the first fastener, through the first opening, through the rail, through the second opening, and to the second fastener.

Road safety barrier assembly has a barrier and an electric circuit that can be supplied with direct current. The circuit includes an outward electric cable and a return electric cable, and sensors along the barrier for detecting impact of a vehicle against respective portions of the barrier, each sensor causing upon impact detection a switching of electric current from the outward electric cable towards the return electric cable at the respective portion of the barrier. A device is arranged so as to measure a voltage value between the outward electric cable and the return electric cable upstream of the sensors. A control unit is predisposed to receive a signal indicating the voltage value measured by the voltage measuring device and is configured to calculate the distance between the voltage measuring device and the location of impact against the road safety barrier, by applying Ohm's Law.

The present invention relates to a module for a road safety barrier (11) comprising essentially a main protection body (12) adapted to be coupled and constrained to at least two support uprights (13) fixed and constrained to the road surface or in the ground immediately adjacent to said road surface, in which said main protection body (12) has an upturned L shaped section to be arranged on said uprights (13) and fixed to them and in which said main protection body (12) has, in its front surface facing outwards, opposite to that facing said uprights (13), at least two wave-shaped enlargements (14) which proceed horizontally and parallel to the ground, said main protection body (12) being made from a special composite material, in which the matrix used for its realisation comes from raw materials recycled from used tyres, that is from the mixing of rubber powder and/or granules containing other recycled plastic materials and their related binders.

Elongated protective barrier apparatuses, assemblies and methods of manufacture and installation, are provided that utilize strips of recycled tire tread for attachment within an elongated recess of a guardrail. The elongated recess includes a base, first and second outwardly tapered walls, a minimum width defined between the outwardly tapered walls and an outer opening opposite the base. The elongated protective barrier includes a base layer and a plurality of additional layers sequentially stacked upon the base layer. The base layer includes a first base layer surface having a first base layer width, and a second base layer. The first base layer width is less than or equal to the minimum width. The plurality of additional layers have widths less than that of the elongated recess and are configured to substantially fill the recess at least up to, if not beyond, the outer opening.

Safety end piece mounted in the front end of metal road barriers, wherein the end piece is frontally provided with a sliding support with blades that, when hit by an out of control vehicle, is capable of moving towards a beam of laminated wood and interfering with the blades with the structure of the beam, in such a way that the interference determines a progressive reduction of the forward traveling speed of the sliding support and absorbs the energy of the impact discharged by the out of control vehicle against the sliding support.

A force-absorbing barrier 10 includes a plurality of concentric chambers 21, 23, 25 and 27 at least partially filled with fluid 42. The walls 22, 24, 26 and 28 defining the chambers are flexible. Fluid passages 30 in the interior walls 24, 26 and 28 between chambers allow fluid flow between the chambers. The fluid flow from chamber to chamber will absorb energy from the impact a motor vehicle, preventing the vehicle from impacting the terminal of a guardrail.

A road safety barrier has a plurality of panels flanking one another at respective vertical lateral edges thereof, made of a material deformable upon impact by a vehicle, and a plurality of vertical support elements supporting the panels. The vertical support elements include a first and a second vertical support member facing one another at the flanked vertical lateral edges of the panels, on opposite sides with respect to two major faces of the panels. The barrier has components for reciprocally blocking the first and the second vertical support member to the two opposite faces of the panels, and longitudinal stiffening elements coupled to the panels at respective upper longitudinal edges thereof.

A barrier having first and second spaced posts interconnected by a rail, wherein the rail and posts are not inserted within one another. In the exemplary embodiments, the parts are hollow in at least the region of the intended interconnection. Each post is connected to the rail by a coupling. Each coupling includes a connector that extends inside the hollow region of the post and rail. The post includes an aperture wherein when assembled the connector extends through the aperture. The connecter includes an abutment that abuts an inside of the post to prevent movement of the connector through the aperture. The connector is moveable further into one of the hollow sections of the post or rail to withdraw the connector from the other of the post or rail. This allows the rail to be disconnected from the post without increasing the distance between the two spaced posts.
