Cement concrete pavement protection paving system for toll lanes

Abstract

The invention relates to a cement concrete pavement protection paving system for toll lanes. The functions of the toll lanes are distinguished through colors; an ETC lane has a colored paving structure, and an artificial toll lane has a black paving structure; and the paving structure comprises a structural lower layer, a structural middle layer and a structural upper layer. The paving system is characterized in that: the structural lower layer is a toll lane cement concrete pavement subjected to sandblasting; the structural middle layer is a high-permeability resin adhesive layer; and the structural upper layer is an anti-skid anti-flushing layer formed by an anti-skid wear-resistant aggregate and an adhesive. The cement concrete pavement protection paving system for the toll lanes has the advantages of high distinguishability and high oil, flushing and skid resistance and improves the operating efficiency and safety function of the toll lanes.

Description

technical field [0001] The invention relates to a protective pavement system for cement concrete pavement of a toll station, in particular to a protective pavement system which takes into account the function of traffic guidance. Background technique [0002] Toll stations are traffic facilities built to collect vehicle tolls, including toll gates (toll islands, toll booths, toll lanes, awnings, toll machines), toll plazas and toll booths. As an important part of toll booths, toll lanes are the only lanes for vehicles to pass through, and are subjected to frequent braking of vehicles. [0003] As one of the main pavement types of high-grade road pavement structure, cement concrete pavement has been widely used in my country because of its advantages of high rigidity, high strength, excellent high temperature stability, and good durability. Most of the toll stations Driveways are paved with cement concrete. In recent years, along with the rapid development of my country's ec...

AI Technical Summary

Problems solved by technology

[0004] (1) Under the condition of frequent braking of the vehicle, the anti-skid effect of the slot notch decays rapidly, and the anti-skid performance is insufficient in humid weather conditions, and the driving safety is poor;

[0005] (2) The color difference between white cement concrete paving and marking lines is small, and the traffic indication is not strong. Under special weather conditions, it is difficult for drivers to control the direction;

[0006] (3) Frequent braking of vehicles in toll lanes, fuel is prone to incomplete combustion, and enters the road with exhaust gas. At the same time, oil leakage, worn tires embedded in the road, etc., are restricted by the characteristics of cement concrete roads, and pollution removal is quite difficult. Toll lane landscape and anti-skid performance are adversely affected

[0007] The existence of the above situation has led to poor anti-skid performance of the cement concrete pavement of the toll lane, unclear markings, poor safety, difficulty in cleaning after pollution, serious damage, etc., such as image 3 Shown:
