Road pavement draining method and drainage structure system

The invention provides a road pavement draining method and a drainage structure system. The road pavement draining method is characterized in that water falling on a lane vertically passes through a lane water-permeable surface layer, arrives at a waterproof bonding layer preventing water penetration, and enters into a water-permeable drainage system located at outer sides of drainage curbstones by a cross slope and the drainage curbstones located at outer sides of the lane; the bottoms of the drainage curbstones are provided with water-permeable curbstone bases; the water-permeable drainage system comprises a broken stone blind drain drainage system arranged at the bottoms and the outer sides of the water-permeable curbstone bases; the bottom of the broken stone blind drain drainage system is provided with a longitudinal drainage water-permeable pipe; and most of the water discharged into the water-permeable drainage system at the outer sides permeates into soil at the outer sides and forms ground water, and the rest of the water passes through the longitudinal drainage water-permeable pipe in the broken stone blind drain drainage system and then is discharged into a municipal pipe. The road pavement draining method solves the problem that rainwater on a drainage bituminous pavement is directly discharged into the municipal pipe, and has functional advantages of good safety, ecological benefits, energy saving and good economical efficiency.
