China Traffic Rubber Long-life Speed bump

Name

Black and yellow.

Width and height direction section for approximate trapezoid or arc.

1. Width ,(300 mm±5 mm)~ (400 mm±5 mm).
2. Height,(25 mm±2 mm)-(70 mm±2 mm).
3. In roads and urban road use rubber deceleration ridges height and width of sizes ratio not greater than 0.7

Complete weight for 20 to 40 t multi-axial car km/h speed through in pavement already fixed rubber deceleration ridges, after test and visual inspection samples, after test rubber deceleration ridges without any breakage, cracking phenomena.

1.  Tore elongation,Rubber deceleration ridges surface materials tore elongation, not less than 200% in roads and urban road use rubber deceleration ridges surface materials tore elongation not less than 25%.
2. Tensile strength,Rubber deceleration ridges surface materials tensile strength of not less than 6.0 MPa, roads and urban road use rubber deceleration ridges surface materials tensile strength of not less than 8.5 MPa.
3. ShaoEr A hardness,Rubber surface material ShaoEr ridges of the slowdown in A hardness 65-85 range.
4. Tear strength,Rubber deceleration material surface skimming tear strength, no less than 20 kN/m.
5. Attrition reduction,Rubber deceleration material surface skimming abrasion reduction is not more than 0.8 cm3 / bachelor km.
6. Impact elastic,Rubber deceleration ridges surface materials not less than 20% of the impact of the elastic.

Rubber is slowing of vehicle ridges unit in the direction of not less than rebellious shoot performance table 1 requirements.

Under various environment after test, rubber deceleration ridges without discoloration, crack, flake, warping etc. Phenomenon, its tore elongation and tensile strength of the still accord with three requirements.

1.  Rubber deceleration skimming the 93 gasoline after wiping, without obvious being dissolved and destruction of trace.
2. Rubber deceleration ridges by diesel after wiping, without obvious being dissolved and destruction of trace.
3. Rubber deceleration skimming the SAE 5W - 30 lubricant after wiping, without obvious being dissolved and destruction of trace.
