However, in national roads in China, particularly in mountainous areas, as the passing vehicles are mostly heavy long-distance freight trucks, common rubber deceleration strips and cast steel deceleration strips are not enough to bear high-frequency high-speed stamping of heavy trucks, and the maintenance and replacement costs of the rubber deceleration strips and the cast steel deceleration strips are high, the deceleration strips on the national roads are mostly cement deceleration humps. One practical situation is that the width, height and width-to-height ratio of the cement speed-reducing hump after multiple maintenance do not meet the requirements of related quality standards and sizes, and the speed-reducing hump on the national road can not be coated with warning colors, because the speed-reducing hump is made of cement and is almost the same as the color of the road surface, the speed-reducing hump can not be distinguished easily when the natural color is dark, the household car is low in chassis and high in speed, when the automobile runs in the national road, if the cement speed-reducing hump almost the same as the color of the road surface can not be found in time, the automobile is supported by the bottom of the automobile easily through the speed-reducing hump, the automobile chassis is easily damaged, and even the automobile oil pipe is cracked.
