What are the quality standards for deceleration?

Rubber deceleration ridge consists of yellow and black rubber deceleration ridge units. The rubber deceleration ridge should be integrally formed, and the outer surface should have a stripe to increase the adhesion.

Each deceleration ridge unit should have a retroreflective material that facilitates nighttime identification in the direction of travel of the vehicle. The surface should be free of air holes, there should be no obvious scratches, lack of material, the color should be uniform, no flash.

Rubber deceleration ridge surface should be pressed out of the name of the production unit. If bolts are connected to the ground, the bolt holes should be countersunk. Deceleration ridge units should be connected in a reliable manner.

The width and height direction of the deceleration ridge unit should be approximately trapezoidal or arc-shaped. Its width should be in the range of (300 mm ± 5 mm) ~ (400 mm ± 5 mm), height should be in the range of (25 mm ± 2 mm) - (70 mm ± 2 mm), on roads and urban roads The ratio of the rubber deceleration ridge height to the width dimension used should not exceed 0.7.
