Rubber speed bumps have strict requirements when they are made, mainly to ensure the quality of the use, so what are the specific performance requirements for rubber speed bumps when they are made? Below we will give you a brief analysis of the performance requirements of rubber speed bumps for your reference when purchasing.
1. Elongation at break, the elongation at break of the surface material of the rubber deceleration belt should not be less than 200%, and the elongation at break of the surface material of the rubber deceleration belt used on highways and urban roads should not be less than 250%.
 2. Tensile strength, the tensile strength of the surface material of the rubber speed bump should not be less than 6.0MPa, and the tensile strength of the surface material of the rubber speed bump used on highways and urban roads should not be less than 8.5MPa.
3. Shore A hardness, Shore A hardness of the surface material of the rubber speed bump should be in the range of 65-85.
4. Tear strength, the tear strength of the surface material of the rubber deceleration belt should not be less than 20kN/m.
5. Wear loss, the wear reduction of the surface material of the rubber speed reduction belt should not exceed 0.8cm3/1.61km.
6. Impact elasticity, the impact elasticity of the surface material of the rubber speed bump should not be less than 20%.
