Why Some Rubber Speed Bumps Are So Durable
As a common traffic facility in our lives, speed bumps not only reduce the speed of the car while driving, but also increase the safety of pedestrians on the roadside.
Generally, speed bumps are installed at crowded people, highway intersections, or important special sections.
The rubber speed hump is made of special rubber and has a certain degree of flexibility.
There is no strong feeling of bumps when the vehicle hits, and the shock absorption and shock absorption effect are good. Because the rubber speed bump has shock absorption, compression resistance, long life, less wear on the car, less noise, yellow and black, distinct colors, no need to repaint every year, beautiful and generous, and simple installation and easy maintenance, so it is now widely used.
Rubber speed bumps greatly reduce accidents at various traffic intersections, and are a new type of special facility for traffic safety.
There is a small hole in the center on both sides of the speed bump. This is the installation hole. The speed bump is fixed to the road with expansion screws.
Therefore, when the vehicle rolls the deceleration belt, the most stressed place is the installation hole, and the first torn part is also the connection hole.
If you cut corners and use recycled rubber to add a large amount of low-cost additives, the quality of the material will be greatly reduced and it will be easy to tear.
To avoid this problem, it is necessary to use natural rubber without adding a large amount of low-cost additives. When rubber products are vulcanized, a steel plate is installed inside the speed bump to connect the two holes respectively. The expansion screws also pass through the steel plate during installation to increase the connection strength of the holes. The steel plate has large and small holes to allow the steel plate better combination with rubber. Adding a meridian can increase the strength.
