The influence of vibration molding method and manual poking molding method on strength and water permeability of polymer pervious cement concrete with water cement ratio of 0.27, 0.30 and 0.33 is studied. It is found that the compressive strength of vibration molding increases with the increasing of vibration time and the water permeability coefficient decreases. The strength of concrete with vibration molding is higher than that of manual poking molding, and the water permeability coefficient is lower. However, the water permeability coefficient with both molding methods is more than 0.5mm/s.
