Description
Technical Field
The utility model relates to a technical field is handled in the road surface design, especially relates to a road surface structure of making an uproar falls in drainage.
Background
Research shows that on a dry road surface, when the driving speed of an automobile reaches 70km/h, the noise of a truck tire becomes the main noise source of the automobile, and for a car and a light truck, when the speed is higher than 45-55 km/h, the noise of the tire becomes the main factor; on a wet road surface, even if the vehicle speed is slow, tire noise becomes the most dominant noise source over other noises. The faster the vehicle speed and the greater the load, the higher the energy level of the tire noise and the greater the proportion of the tire noise in the vehicle running noise. Tire noise is noise generated by tire-road interaction of a running vehicle, tire-air interaction and tire deformation, noise pollution constitutes harm to people, animals, instruments and buildings, the harm degree of the noise mainly depends on the frequency, intensity and exposure time of the noise, the reason and mechanism of tire noise generation are complex, and although factors generating noise excitation sources are numerous, all tire/road noise is caused by tire-road contact, tire deformation and tire-air interaction. At present, in order to reduce the influence of noise on people, people are focused on how to reduce the noise generated on the road surface.
