PROBLEM TO BE SOLVED: To provide a construction method for a porous pavement, which can shorten a curing time and make the start of service earlier, by making a paving-material mixture efficiently react with water from a surface section to a deep section, so as to accelerate curing, after the paving-material mixture is laid on a bed road surface on a job site. SOLUTION: Firstly, on a construction site, elastic aggregate, rigid aggregate, and a moisture-curing type one-component urethane resin binder are charged at a predetermined ratio (e.g. 50:50:30) into a mixer etc., and mixed together to be made into the paving-material mixture. The paving-material mixture manufactured in this way is laid as a pavement surface with a predetermined thickness (e.g. 30 mm), the percolation amount of which is set at 100 cc/15 sec or more, on the bed road surface on the job site by means of a prescribed machine etc.; after that, a predetermined quantity of water is sprayed on the pavement surface after a lapse of predetermined time; and subsequently, a predetermined quantity of water is sprinkled after a lapse of predetermined time. Preferably, the sprayed quantity of water is in the range of 50-500 g/m<SP>2</SP>, and the sprinkled quantity of water is 800 g/m<SP>2</SP>or more. Preferably, the sprinkling of water is repeatedly performed twice or more at intervals of predetermined time, and the temperature of water is set to be in the range of 30-80°C.
