PURPOSE: A cleaning method for low noise and permeable asphalt pavement is provided to prevent the scattering of water by running vehicles and thus secure driver's field of view. CONSTITUTION: A cleaning method for low noise and permeable asphalt pavement is as follows. A maintenance vehicle is driven with a magnetic bar of an iron material collector maintained to be close to the porous superficial layer so as to pick up and remove iron materials scattered on the ground or jammed in pores with the magnetic force(S100). High pressure cleaning water is sprayed on the porous superficial layer to clean the superficial layer and eliminate foreign materials from the pores and, at the same time, the waste water and foreign materials are sucked into a first suction duct and collected into a sewage tank(S200). High pressure cleaning water is secondly sprayed on the cleaned superficial layer to clean the superficial layer and eliminate foreign materials from the pores and, at the same time, the waste water and foreign materials are sucked into a second suction duct and collected into the sewage tank(S300).
