Combined pouring type road structure and design method thereof

The invention discloses a combined pouring type road structure which comprises a lower roadbed, an upper roadbed, a transition layer, a subbase layer, a base layer and a surface layer which are sequentially arranged from bottom to top, the lower roadbed is a natural roadbed, the upper roadbed and the transition layer are formed by pouring flowing solidified soil, and the base layer and the subbase layer are formed by pouring flowing solidified muck. The surface layer is an asphalt concrete or cement concrete pavement; wherein the flowing solidified soil is composed of waste soil materials, clear water and a cementing agent; the flowing solidified muck is composed of waste muck containing gravel aggregate, clear water and a cementing agent. The invention further discloses a design method of the combined pouring type road structure. The method has the advantages of being good in overall performance, high in waste residue soil resource utilization rate and the like, and can be applied to new construction and rec
