3.The end treatment tests are conducted with the vehicle striking the end treatment head-on, striking the end treatment at an angle, and striking the guardrail just downstream from the end treatment. The still shots shown below are those of a gating, energy-absorbing guardrail system. The guardrail is an example of this type of system.
For head-on impacts, an energy-absorbing guardrail end terminal should absorb the energy of the impact, and extrude the guardrail away from the vehicle as shown below.
4.Multiple types of guardrail are available on the road, depending on the specific needs of the road and its users.
The most common guardrail types include:
W-shaped steel guardrail: W-shaped steel guardrail is the most common type of guardrail on roads. They consist of a series of steel beams installed on columns, designed to absorb the impact of collisions. W-shaped steel guardrails can effectively prevent vehicles from entering oncoming vehicles or completely leaving the road.
Cable guardrail: Cable guardrail is another type of guardrail that is becoming increasingly popular on highways and other roads. They are composed of high-voltage cables installed on utility poles, designed to absorb the impact of collisions. Cable barriers can effectively prevent vehicles from entering oncoming vehicles or completely leaving the road.
5.Concrete guardrail: Concrete guardrail is a type of guardrail commonly used on highways and other highways. They are composed of concrete barriers installed on pillars, designed to absorb the impact of collisions. Concrete barriers can be very effective in preventing vehicles from entering oncoming vehicles or completely leaving the road.
Double traffic guardrails: Double traffic guardrails effectively isolate vehicles driving within the factory area, avoid direct collisions, and protect company personnel, equipment, assets, and profits. After impact testing, Auden's double-layer traffic guardrail can withstand impacts from a 6-ton forklift at a speed of 9 kilometers per hour without damage.
Metal guardrail: Metal guardrail is the most common type of highway guardrail. They are usually made of steel or aluminum and have many different designs. The most common design is a W-shaped steel guardrail, which consists of a series of connected W-shaped metal beams. Metal guardrails are usually the preferred choice because they are durable and can withstand significant impacts.
