Orange New Advanced EVA Material Highway Revolving Guardrail
Application
1. Adopt high-quality original material
Roller EVA material with elastic characteristics is used as raw
material, which can slow down the lateral impact process of the
out-of-control vehicle. Moreover, the rotating barrel can rotate
around the column under a certain impact, driving the
out-of-control vehicle to return to the correct driving direction.
2. Tunnel entrance transition
The different widths of roadbed (bridge) and tunnel cross-sections
are important reasons for the high number of accidents at tunnel
entrances, which require the transition of guardrails to complete
the cross-section change. The rolling barrier is used in the tunnel
entrance, which can provide a strong enough guidance function to
assist the driver to complete the road environment change under the
premise of ensuring the collision prevention demand.
3. Interchange exit triangle end
The interchange exit is sensitive to the direction of travel,
requiring the driver to choose the correct route based on the
judgment of the guiding information, and the poor combination of
interchange exit lines will easily cause the driver to hesitate in
making decisions before the exit triangle end, which is an
unfavorable factor affecting operational safety. Statistics show
that interchange exit sections are often accident-prone, so it is
advisable to use rotating movable guardrails to strengthen the
guidance and protection of the exit area.
4. Night vision blindness and no street light road
At night when the road lighting is not enough and road border
accidents occur, the need to play a warning role through the bright
color of the guardrail to the driver, and the driving environment
changes also need to be timely reminders to the driver, in order to
prompt the driver to complete the vehicle control process
conversion. Rotating collision guardrail for the night road
environment, can guarantee the collision demand premise, provide
strong enough to induce function, assist the driver to complete the
road environment changes.
