The invention discloses a drainage-type municipal road and a construction method thereof. The drainage-type municipal road orderly comprises a soil layer, a ballast layer, a graded crushed stone layer, a concrete layer and an asphalt layer from bottom to top. Two sides of the asphalt layer are provided with drainage grooves. Drainage pipes communicated with the drainage grooves are arranged belowthe drainage grooves. The middle of the asphalt layer is provided with a barrier. The barrier is provided with a blower. The blower is connected to a downward air inducing pipe. The lower end of the air inducing pipe is provided with a first blowing duct and a second blowing duct downward inclining to two sides of the ballast layer. The two sides of the ballast layer are provided with the drainagegrooves for rainwater drainage. The blower is used for blowing. The first blowing duct and the second blowing duct guide air blown by the blower to two sides of the asphalt layer. Air blown by the blower makes rainwater on the road fast flow into the drainage grooves in two sides of the road. The drainage-type municipal road prevents damage caused by large dynamic water pressure of surface wateron the asphalt layer to the asphalt layer under traffic load.
