Anti-cracking asphalt concrete composite pavement structure
The invention relates to the technical field of road construction, and discloses an anti-cracking asphalt concrete composite pavement structure. The pavement structure comprises a macadam roadbed layer, a supporting layer flatly laid on the macadam roadbed layer, a concrete layer flatly laid on the supporting layer and a pavement layer flatly laid on the concrete layer. The supporting layer comprises a steel frame horizontally placed above the gravel roadbed layer and a plurality of supporting rods horizontally arranged in the steel frame, the two ends of each supporting rod are fixedly connected with the steel frame, and the height of the supporting rods is equal to that of the frames. The asphalt concrete composite pavement structure has excellent loading performance and cracking resistance, so that the service life of an asphalt concrete pavement is prolonged.
本发明涉及道路施工技术领域，公开了一种抗开裂沥青混凝土组合路面结构。包括碎石路基层、平铺于碎石路基层上方的支撑层、平铺于支撑层上方的混凝土层、平铺于混凝土层上方的路面层；所述支撑层包括水平放置于碎石路基层上方的钢架框和若干水平设于钢架框内部的支撑杆，所述支撑杆的两端均与钢架框固定连接，所述支撑杆的高度与边框的高度等高。本发明沥青混凝土组合路面结构具有优良的负载性能和抗开裂性能，从而延长沥青混凝土路面的使用寿命。
