Rubber Speed Breaker Bump

The physical properties of rubber speed breaker bumps are crucial considerations in their design and performance. These properties impact the effectiveness, durability, and safety of these traffic calming devices. Here are some key physical properties of rubber speed breaker bumps:

1. **Hardness:** The hardness of the rubber is measured on the Shore durometer scale. Rubber speed bumps are designed to have a specific hardness to ensure durability and effectiveness. A balance between hardness and flexibility is crucial to withstand the load from vehicles while providing a comfortable ride.

2. **Elongation at Break:** Elongation at break measures the stretch ability of the rubber before it breaks. A higher elongation at break indicates greater flexibility, allowing the rubber to deform under pressure and return to its original shape.

3. **Tensile Strength:** Tensile strength is the maximum amount of tensile (pulling) stress that a material can withstand before breaking. It reflects the rubber's resistance to being stretched or pulled apart.

4. **Compression Set:** Compression set measures the ability of the rubber to recover its original shape after being compressed. For rubber speed bumps, good compression set resistance ensures that the bumps return to their normal state after vehicles pass over them.
