Cement concrete pavement structure provided with continuous steel bars
The invention discloses a cement concrete pavement structure provided with continuous steel bars. The pavement structure comprises a base layer. Roller compacted concrete is adopted in the base layer. A broken stone hardcore is laid below the base layer. Cement concrete surface layers are laid on the base layer. The cement concrete surface layers include the upper surface layer and the lower surface layer. Rubber cement concrete is adopted in the upper surface layer. A transverse induction kerf is arranged on the edge of the upper surface layer on the left side of the driving direction. The continuous transverse steel bars, the continuous longitudinal steel bars and a slidable support are arranged at the portion, within the range of a carriageway and one half of the width (L) of a hardened verge, of the lower surface layer. Plain concrete is formed at the portion, within the other half of the width (L) of the hardened verge, of the lower surface layer. A longitudinal joint is arranged at the portion one half of the width of the hardened verge. A bituminous concrete anti-scouring layer is arranged between the base layer and the surface layers. The pavement structure can solve the problems of existing cement concrete pavements and continuous reinforced concrete pavement structures and can be widely applied to high-grade highways, tunnel pavements and the like on the heavy-duty traffic condition.
