The invention discloses a pavement system for preventing waterlogging and supplying underground water. The pavement system comprises a roadbed, a base layer and a road surface from bottom to top, wherein the road surface is the water permeable road surface formed by paving an open-graded asphalt mixture; the roadbed is the water permeable base layer formed by paving a flexible material or a water impermeable base layer formed by paving a semi-rigid material, and if the water permeable base layer is adopted, a water impermeable layer is paved between the roadbed and the base layer; the road surface is divided into a traffic lane and a sidewalk; the sidewalk is positioned on the outer side of the traffic lane; a drainage ditch is arranged on the edge of the traffic lane; a water storage tank is arranged below the drainage ditch; a water drainage pipe is arranged on the outer side of the water storage tank; a seepage ditch is arranged on the lower side of the water storage tank; the water drainage pipe is used for communicating an urban drainage system; the seepage ditch is directly communicated with deep underground water. According to the system for preventing waterlogging, collecting rain water and supplying underground water, the problems that at present, cities are suffered from waterlogging due to sudden heavy rain in the rainy season, and only water drainage measures are adopted, which cause underground water insufficiency in the cities can be solved.
