1. What is the structural classification?Concrete median barrier designed for highway traffic separation and impact mitigation
2. How does the F-shape barrier keep cars safe?When a car hits the F-shape barrier, its lower break point keeps the front of the car from lifting too much. This helps the car stay on the road and reduces the chance of it rolling over.
3. Why is the slope break point lower on the F-shape barrier?The break point on the F-shape barrier is 255 mm above the road, which is 75 mm lower than the Jersey barrier. A lower break point makes the car’s front lift less, keeping the tires on the road.
