The rubber speed ridge consists of yellow and black rubber speed ridge units. rubber
The deceleration ridges shall be integrally formed and the outer surface shall have stripes to increase adhesion. Each deceleration ridge unit shall face the direction of traffic at night
Reflective material for easy identification.
The surface should have no pores, no obvious scratches, lack of material,
Uniform color and no flash. The name of the production unit should be pressed on the surface of the rubber deceleration ridge
. If bolts are used to connect to the ground, the bolt holes should be countersunk. The unit
The deceleration ridge should be connected reliably. deceleration ridge unit in width
The cross-section in the direction of height and height should be approximately trapezoidal or arc-shaped. The width dimension should be within
(300mm±5mm)~(400mm±5mm), the height dimension should be within
(25mm±2mm) ~ (70mm±2mm) range. Height of rubber speed bumps for highways and city roads
The ratio to the width dimension should not be greater than 0.7.
Pressure resistance. A two-axle car weighing 20 tons travels at a speed of 40 km/h
By means of rubber deceleration ridges fixed to the road surface.
After testing, the samples were visually inspected. After testing, rubber deceleration ridges
Should not be damaged or cracked.
