The invention discloses an urban road water permeability cement concrete pavement structure and a construction process thereof. The pavement structure comprises an asphalt stable water draining base layer paved on a roadbed and a road surface layer paved on the asphalt stable water draining base layer, wherein the road surface layer is a first road surface layer or a second road surface layer composed of a lower surface layer and an upper surface layer paved on the lower surface layer, a plurality of water permeability pile bodies are arranged in the roadbed, the water permeability pile bodies are polyvinyl chloride (PVC) tubular pile bodies, lower portion pile bodies of the PVC tubular pile bodies are sleeved in first PVC tubes provided with water permeable holes, and upper portion pile bodies are sleeved in second PVC tubes. The construction process comprises the steps of pressing the roadbed; drilling pile holes; constructing water permeable pile bodies; constructing the asphalt stable water draining base layer; and constructing the road surface layer. The structure is reasonable in design, convenient to construct, good in using effect and capable of having capacity of absorbing heat and enabling rain to seep and effectively resolving the actual problems in ordinary cement concrete road surfaces.
