What are the factors that cause damage to highway guardrails?

Cast steel speed bumps are installed on the road surface with some speed reduction signs. Gas station vehicles frequently appear, so speed limit signs, collision barriers, speed reduction zones and other facilities will be set up at the station to remind the station to slow down and protect the safety of personnel and equipment. Especially, it is necessary to install speed reduction gas stations. So, we will further discuss this topic on which speed reduction zone to choose and which suitable location to install. Below, I will share some of your opinions to explore. Many driving friends often encounter different types of deceleration zones, and there are mainly the following types of cast steel speed bumps:

1. Cast steel speed bumps, commonly found at village intersections, have low construction costs but are on the high side with low color rendering. The color is similar to the road surface and visually unclear, causing emergency braking, jolting, and even hitting the chassis when driving in front. 2, Cast steel speed bumps are commonly found in workplace squares, residential areas, and other places, with a height of about 5 centimeters above the ground. They are generally fixed to the ground with M12X14 sleeve expansion screws, which are yellow and black in color, visually obvious, and not expensive. However, their service life is short, and rubber speed bumps are often exposed from screws and long screws, which can easily damage tires. To replace the ground, a new speed bump needs to be repaired and fixed to the ground.

3. Cast steel speed bumps are commonly found at highway intersections, toll stations, and other places. Rubber speed bumps with better service life are superior to rubber speed bumps, but their price is much higher.

4. Paving bricks in point like deceleration zones are commonly found on highways, urban roads, and other fast roads. This type of deceleration is slightly higher than that of roads, forming a film and generally using glass bead primer and paint. They are beautiful, wearable, and have visibility at night. When vehicles walk on them, they emit a strange whistle sound to remind drivers to slow down.

5. Reflective hot melt marking speed reduction zone. Just like the difference in speed reduction compared to the same material, the production process is different from that of a cross highway strip. There is a distance between each line, with intermittent vibrations above to remind drivers to slow down.
