When i drive across speed bumps on the street, my car always gives out loud noises "bang bang!!" I know they installed speed bumps on the road to reduce our driving speed and keep us safer. But each time when my car "bangs", i feel my heartstrings tugged. God...don't make my car shaking like that...and my wheel-tires!!!...
I've observed the speed bumps on the street for a long time. In Picture 1/ 2/3, the rubber speed bump is in a poor condition, with exposed nails seriously threatening traffic safety. Why?
In both sides of speed bump, there are small holes used for fixing with expansion screws. Theses holes are at the top pressure-position when vehicle passes by the speed bump, making the speed bump brushed off and steel nails exposed.
You can see from the pictures that the nails on the road are ready to prick through wheels like steel pins. Jerry-building using recycled rubber or adding a large number of low-cost additives causes the material strength to decline significantly.
I don't hope to see speed bumps become tire-killers, but be the "guard" of saving life. Also hope to see relative departments try to find out the solutions to solve this problem.

Reason: some expression mistakes
Live in an area that gets snow. Townships and communities have some pretty heated debates over whether or not to put in speed bumps( usually to safeguard children in the area) which then damage snowplow blades.
Sell them new ones then. After all, that is one of the products that SZYDM (Shenzhen YDM Reflector Co., Ltd.) manufacturers.
I am very glad you can make some comment there, but products manufactured by Shenzhen YDM are completely not that kind. Shenzhen YDM has found out the solutions to solve this problem:
(1) Use natural rubber in stead of recycled rubber. No low-cost additives.
(2) Connection holes lined with steel plate, and connected to each other.
During the rubber vulcanization process, place a steel plate inside the speed bump and connect the two holes, so that the fixing expansion screws will not only get through holes but also steel plate. In this case, connection is strengthened.
(There are small holes in steel plate which is in the same positions as the fixing holes)
they look awful dont china have any asfalt left ? so they have to use old brakeshoes from buses and trucks?
Thanks for asking.
But in China, speed bumps are not like what you've described. I am sure you will change your mind on China if you come and take a look. Those photos are not from China, and are posted here just to remind all guys in the world dealing this matter of taking this into consideration when installiing this facility.

Yeah, i agree with you. It's very controversial in the areas with heavily snowy days.
