The utility model provides an expansive soil flagstone interlayer core-spun roadbed structure, which relates to the technical field of expansive soil and comprises a circulation layer, a foundation is arranged at the top of the circulation layer, a roadbed is arranged at the top of the foundation, a plurality of first micropores are formed in the top of the circulation layer, and a flow guide pipe is fixedly communicated with the bottom of the circulation layer close to the edge. An underground water path is arranged below the flow guide pipe, and the top of the circulation layer fixedly communicates with a plurality of water collecting pipes. The interior of the foundation is composed of the expansive soil and the rubbles, when the water content in the foundation is very large, the expansive soil expands, at the moment, water is extruded to enter the multiple water collecting pipes through the second micropores, then flows to the circulation layer rapidly through the interiors of the water collecting pipes,
