Provided is a road structure for a high-groundwater city, comprising, laid in sequence, a bottom layer bidirectional geogrid, a pebble layer, a gravel layer, a cement-soil isolation layer, and a pavement structure layer; the bottom layer bidirectional geogrid is inversely packed on the pebble layer; from top to bottom, the pavement structure layer consists of the following structural layers having certain thicknesses: a medium-grain asphalt concrete layer, an asphalt adhesive layer, a coarse-grain asphalt concrete layer, an asphalt permeable layer, a cement-stabilized gravel layer, and a gap-filling gravel layer. The road structure is suitable for use in roads in cities having high groundwater.
