Abstract

A transformed continuously reinforced concrete pavement structure using a short reinforcing bar and crack induction. The structure includes a crack induction part combined with short reinforcing bars spaced apart from each other. The short reinforcing bars replace continuous reinforcing bars in a concrete pavement layer of a continuously reinforced concrete pavement structure.

Claims (19)

1. A reinforced concrete pavement structure, comprising:

a crack induction part;

reinforcement bars extending from the crack induction part and oriented perpendicular to the crack induction part; and

a transverse reinforcing bar extending from the crack induction part and oriented parallel to the crack induction part,

wherein the reinforcement bars oriented perpendicular to the crack induction part are spaced apart from one another.

2. The structure of claim 1 , wherein the crack induction part is embedded in a concrete pavement layer, and wherein the crack induction part comprises an anti-attaching treatment layer on at least one surface of the crack induction part.

3. The structure of claim 2 , wherein the crack induction part is made of concrete, comprises a triangular cross-sectional shape, and comprises a rectangular cross-sectional shape extending from the triangular cross-sectional shape, and wherein the anti-attaching treatment layer is applied to a surface of the crack induction part opposite to the inclined surface.

4. The structure of claim 3 , wherein the anti-attaching treatment layer is oleophilic as a result of a hydrophobic surfactant applied to the anti-attaching treatment layer.

5. The structure of claim 1 , wherein the crack induction part comprises a cut groove formed on an upper surface of a concrete pavement layer.

6. The structure of claim 2 , wherein the crack induction part comprises a sheet shaped membrane disposed in the concrete pavement layer.

7. The structure of claim 2 , wherein the reinforcement bars oriented perpendicular to the crack induction part are disposed on the transverse reinforcing bar so as to be orthogonal to the transverse reinforcing bar, and a continuous reinforcing bar is arranged between the reinforcement bars.

8. The structure of claim 3 , wherein the reinforcement bars oriented perpendicular to the crack induction part are embedded in an area of the rectangular cross sectional shape of the crack induction part so as to be exposed at opposite ends of the transverse reinforcement bar, the transverse reinforcing bar is embedded in a lower part of the crack induction part, an opening is formed between portions of the crack induction part in which the reinforcement bars oriented perpendicular to the crack induction part are embedded so as to expose the transverse reinforcing bar, and a continuous reinforcing bar is arranged in the opening so as to be supported by the transverse reinforcing bar.

9. The structure of claim 8 , further comprising an assistant transverse reinforcing bar, wherein the reinforcement bars oriented perpendicular to the crack induction part comprise downward bent parts at opposite ends, the assistant transverse reinforcing bar is disposed between the downward bent parts, and wherein the continuous reinforcing bar is supported by the transverse reinforcing bar and the assistant transverse reinforcing bar.

10. A method of manufacturing a transformed continuously reinforced concrete pavement structure, the method comprising:

combining a crack induction part with reinforcement bars and a transverse reinforcing bar; and

configuring the reinforcement bars in a concrete pavement layer of a continuously reinforced concrete pavement (CROP) structure,

wherein the reinforcement bars, other than the transverse reinforcing bar, extend from the crack induction part and are oriented perpendicular to the crack induction part,

wherein the transverse reinforcing bar extends from the crack induction part and is oriented parallel to the crack induction part, and

wherein the reinforcement bars oriented perpendicular to the crack induction part are spaced apart from one another.
