Problems solved by technology

Thermoplastic vibration markings and rubber speed bumps are two commonly used deceleration facilities on expressways in my country. However, the force of thermoplastic vibration markings to force deceleration is not enough, and the speed limit effect on large trucks on expressways is not obvious; The speed has a certain control effect, but its durability is poor. It not only destroys the road surface during installation, but also causes great damage to the vehicle due to the fixing screws left after scrapping.

Abstract

The invention discloses an energy-dissipating and decelerating pavement on a long downhill slope and a construction process thereof. The energy-dissipating deceleration road surface consists of deceleration zone I composed of three thermoplastic protrusion-type vibration markings perpendicular to the driving direction, deceleration zone II composed of one to three hump-type asphalt concrete-based deceleration belts perpendicular to the driving direction, and The deceleration area III formed by one or two deceleration spikes. The energy-dissipating deceleration pavement construction process mainly includes the steps of pavement pretreatment, road line drawing for installation, installation and maintenance of deceleration facilities, and the like. In the present invention, the deceleration zone I mainly serves to remind the driver to decelerate; the deceleration zones II and III mainly play the role of forced deceleration, and can prevent the driver's visual fatigue and numbness at the same time, thereby preventing the driver from driving again after deceleration. Accelerate immediately to achieve the purpose of long-distance speed control, and the deceleration road has no harm to the vehicle, the deceleration setting is durable, the construction process provided is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of traffic facilities, and provides a long downhill energy-dissipating and decelerating pavement and a construction process thereof. Background technique [0002] With the rapid development of the transportation industry, the level of highway construction in our country has been continuously improved, and the quality of highway pavement is getting better and better, so the speed of driving on the highway is getting faster and faster, but there are more and more traffic accidents. Especially for expressways in mountainous areas, due to the limitation of their own geographical conditions, many complicated driving routes have been produced in the process of expressway construction, and the complexity of mountain climate has brought huge hidden dangers to expressway driving safety. Mountainous highways often contain long slopes and continuous downhill sections. Due to excessive speed and brake failure caused by ...
