The invention provides a prestressed highway roadbed plate, and relates to the technical field of roadbed base plates. The prestressed highway roadbed plate comprises two pouring layers and a prestressed layer, the pouring layers and the prestressed layer are integrally formed or fixedly connected, and the two pouring layers are arranged on the two sides of the prestressed layer respectively; a plurality of reinforcing ribs are arranged in the pouring layer, and the reinforcing ribs are embedded in the pouring layer in the direction from the pouring layer to the prestress layer. According to the prestressed highway subgrade board, the reinforcing ribs are arranged in the pouring layer, so that the strength and the rigidity of the pouring layer can be enhanced under the condition that the wall thickness of the pouring layer is not increased, the material consumption is reduced, the weight is reduced, the cost is reduced, and the phenomenon that the pouring layer is distorted and deformed due to uneven stress caused by the difference of the wall thickness of the pouring layer can be overcome. Therefore, the prestress capacity of the highway subgrade board is effectively improved, the tensile elastic strength of the highway subgrade board is improved, the original resistance is higher, and the phenomenon of distortion deformation or cracks is not prone to occurring.
本发明提出了一种预应力公路路基板，涉及路基基板技术领域。该预应力公路路基板包括浇注层和预应力层，浇注层和预应力层一体成型或固定连接，浇注层的数量为两层，两层浇注层分别设置于预应力层两侧；浇注层内包括若干加强筋，若干加强筋沿浇注层朝向预应力层的方向嵌设于浇注层内。该预应力公路路基板通过在浇注层内设置有若干加强筋，其能够在不加大浇注层壁厚的条件下，增强浇注层的强度和刚性，以节约材料用量，减轻重量，降低成本，其可克服浇注层因壁厚差别带来的应力不均所造成的浇注层歪扭变形。进而有效的提升该公路路基板的预应力能力，进而增加其受拉的弹性强度，使原本的抗性更强，不容易发生扭曲形变或裂缝的现象。
