The performance of untested steel guardrail systems has been observed and commented on by experts in the field of the Middle East, with common observations showing that impacting vehicles have "splintered" W Beam Guardrails. This risk can be mitigated by using a system that has been tested to the standard (US NCHRP350 or MASH) such as Ezy-Guard.
In order to improve road safety, Chinese highway guardrail standards are constantly improving. This paper will briefly introduce the evolution of Chinese highway guardrail from the surface treatment of waveform guardrail and the standard specification from two angles.
Studies have shown that approximately 1.25 million people die in road accidents each year. Any research that can be used to reduce this number would be a welcome move. In many cases, vehicles hit guardrails on the side of the road, and this impact can cause greater injuries. Originating in South Korea, rolling barrier technology was created, a rotating guardrail technology that will increase the likelihood of saving lives.
Highway guardrails are installed on both sides of the road and are designed to absorb the impact of vehicles and redirect them back onto the road.
Roller Barrier is a road safety protection system that attempts to keep vehicles in their lane and prevent them from colliding with other vehicles. Conventional w beam guardrails can reduce accidents, but when a vehicle collides with a barrier, it can cause significant damage to vehicles and even result in injuries or fatalities. For this reason, the Korean company designed the " Roller Barrier System", which converts impact energy into rotational energy. The Roller Barriers are barriers fitted with rollers, consisting of a number of round EVA barrels (almost like tyres), connected by round steel posts.
A rotating Guardrail is also called a Roller Barrier, when the vehicle and the guardrail collide, can prevent the vehicle from rushing out or overturning the road or under the bridge, at the same time, through its deformation to absorb the impact energy or through the roller guidance to promote the vehicle for energy transformation, reduce the damage to the vehicle and the occupants to reduce the formation of serious accidents possible.
Have you ever wondered what highway guardrails are doing? The main purpose of a highway guardrail is to form a safety barrier to help protect motorists who bear off the road.
