Red sandstone roadbed structure

The utility model discloses a red sandstone roadbed structure which comprises a red sandstone layer and a soil base layer, a lime soil layer is laid on the soil base layer, and a plurality of concrete blocks are poured and laid on the lime soil layer at intervals. The red sandstone layer is laid and covered on the plurality of concrete blocks, and a pavement gravel supporting layer is laid on the red sandstone layer. According to the red sandstone roadbed structure, the red sandstone material serves as a filling material in the roadbed, the red sandstone layer is limited in the space and limited on the outer surface of the structure, and when all layers in the roadbed are compacted and leveled, the red sandstone layer is made not only to serve as a single layer surface but also to be embedded into the concrete square blocks, so that the roadbed structure is compact and leveled; therefore, in the construction process of the roadbed and the road surface, the damage of water to the red sandstone layer is slowed
