Problems solved by technology

On the one hand, traffic mixes on the road, which will inevitably cause low-speed vehicles to block the passage of high-speed vehicles, which greatly reduces the traffic capacity of the road; Poor stability in high temperature environment, under the action of vehicle load, especially under the action of large trucks, it is easy to form ruts, which affects the comfort and safety of driving

Embodiment 2

[0059] Such as Image 6 As shown, the pavement structure of the traffic road in this embodiment, on the basis of Example 1, the contact surface between the steel-concrete composite pavement, the asphalt concrete pavement and the base layer is the interlayer of the pavement, which is characterized in that along the longitudinal section of the pavement Direction, the lower surface of the base layer and the steel-concrete composite pavement, the upper surface of the asphalt concrete pavement, that is, the pavement layer is an interlayer embedded matching structure.

[0060] In this embodiment, the upper surface of the steel-concrete composite pavement and the asphalt concrete pavement has a concave structure, and the lower surface of the base layer has a convex structure that matches the concave structure. The shape of the concave structure and the convex structure of the base layer is arc, trapezoid, triangle or uniform spherical cap structure; or

[0061] The upper surface of the st...

Embodiment 3

[0065] In the pavement structure of the traffic road in this embodiment, on the basis of the second embodiment, there are a plurality of steel-concrete composite pavements, and between the base layer and the asphalt concrete pavement. The steel belt is provided with an electric heating device, the electric heating device is electrically connected with a power source, and the steel belt is arranged at intervals. The electric heating device is an electric heating belt, an electric adding rod, an electric heating paint layer or an electric heating net. An FRP cloth waterproof layer is arranged between the asphalt concrete pavement and the base layer, and the FRP cloth waterproof layer is arranged above the electric heating device.

[0066] In this embodiment, the electric heating device installed in the steel-concrete composite pavement or between the base layer and the asphalt concrete pavement is energized, and the pavement can be conveniently heated to achieve the purpose of auto...

Abstract

The invention relates to a pavement structure for a traffic road. The pavement structure for the traffic road comprises a steel-concrete combined pavement, an asphalt concrete pavement and a base layer arranged on the steel-concrete combined pavement and the asphalt concrete pavement. The steel-concrete combined pavement and the asphalt concrete pavement are laid on the base layer. A road parting line arranged in the extending direction of the road is arranged between the steel-concrete combined pavement and the asphalt concrete pavement. A road shoulder is arranged on the edge of the outer side of the steel-concrete combined pavement. By the adoption of the pavement structure for the traffic road, the passage capacity of the road is improved, and the service life of the road is prolonged.

Description

Technical field [0001] The invention relates to a pavement structure of a traffic road. Background technique [0002] There are two main forms of highway pavement in our country, namely, asphalt pavement and steel-concrete composite pavement slab. Both pavement forms have their own advantages. Asphalt pavement has the advantages of smooth surface without joints, low driving vibration, low noise, fast open traffic, easy maintenance, suitable for pavement construction in stages, and is an important structural form of my country's pavement; its disadvantage is high temperature sensitivity. In summer, the strength decreases. If the control is not good, the pavement will become soft and oily or the emulsified asphalt will be damaged by shear cracking. When the asphalt material becomes brittle at low temperature, it may cause pavement cracking. In summer, the temperature of asphalt pavement is poor under high temperature. Plastic deformation occurs under the action of the vehicle, and...
