Road barriers are the devices designed for the following purposes: to prevent a vehicle from driving off the roadside or a bridge structure (bridge, overpass, ramp, etc.), crossing the traffic line, colliding with an oncoming vehicle, hitting massive obstacles and structures located on the roadside, in the right of way of the road or on the traffic line (retaining road barriers for vehicles); to prevent the pedestrians from falling off a bridge structure or embankment (retaining road barriers for pedestrians); to streamline the movement of pedestrians and prevent animals from entering the carriageway (limiting road barriers).
In accordance with GOST 33127–2014 and GOST R 52606–2006, road barriers are divided into two main classes according to their purpose - retaining and limiting. Combined road barriers are also used.
Retaining road barriers are divided into the following types according to their principle of operation:
side road barriers for vehicles (guardrail, curb, parapet, cable, combined)
frontal road barriers for vehicles (telescopic, elastoplastic, water-filled)
retaining road barriers for pedestrians (various types of handrails and combined designs)
The Passive Safety Laboratory of the TC NICIAMT FSUE "NAMI" has all the necessary equipment and infrastructure for field testing of retaining road barriers in accordance with the technical requirements of GOST 33128-2014, according to the GOST 33129-2014 methodology, and it is also possible to test various elements of road infrastructure, other types of road barriers, anti-ram devices of various types and designs, all in accordance with the design documentation and technical specifications submitted by the manufacturer.
