The weather is hot in summer, and the accumulated water is not discharged smoothly after the rain. Through the high temperature of the sun, the accumulated water will quickly evaporate to form water mist, which will block the driver's sight and easily cause the driver's panic, thus causing serious traffic accidents.
In addition, in the cold winter, it will pile up on the road surface after snowing, and it will form icing phenomenon on the road surface after being crushed by cars, which will reduce the friction coefficient between the ground and the car tires, resulting in the car slipping easily and the brakes not being used. The light reflected by the sun and snow will also affect the driver's sight and aggravate the formation of traffic accidents.
Due to the failure of drainage engineering, the quality of pavement is damaged.
The asphalt compaction standard of pavement does not meet the requirements, or the pavement has not been maintained for a long time, resulting in cracking of asphalt surface layer of pavement. If the road surface is not drained in time after the rain, it will directly penetrate into the cracks of the road surface, resulting in the separation of adhesion substances such as asphalt and gravel.
The degree of adhesion between stripped asphalt and other mixtures forms a large area of potholes on the road surface, which reduces the driving comfort and has a great influence on the smooth running of motorcycles and bicycles.
