This application discloses a cement-stabilized crushed stone layer structure, belonging to the technical field of crushed stone layers. The cement-stabilized crushed stone layer structure includes a grid frame, the interior of which is equipped with a filling skeleton assembly. The filling skeleton assembly includes multiple interconnected composite plates, with adjacent composite plates forming a honeycomb structure. The inner wall of the grid frame is fixedly connected to the adjacent composite plates. A through-hole is provided at the center of each composite plate. The honeycomb composite plates within the grid frame decompose the shear force under horizontal load into axial pressure, fully utilizing the compressive strength of concrete, effectively resisting pavement deformation, improving structural bearing capacity, and extending pavement service life. The honeycomb structure restricts the dispersion of crushed stone, facilitating compaction and shaping after cement pouring. The burr membrane within the anti-scattering holes forms a mechanical bond with the cement, enhancing the bond strength between the cement and the composite plates, ensuring tight fusion and improving the overall integrity of the pavement structure.
