Abstract: The design and development of pervious solvent-free polyurethane floor coating were discussed according to pervious substrate and its property, development and performance of pervious floor coating, and different design structures under different project conditions.As polyurethane resin reacts, its viscosity, temperature and modules were tested continuously.And their effects on operation were analyzed And the effects of polyurethane dosage and stone chip size on permeability of floor coating were evaluated. Physical properties including permeability, freezing resistance, and strength and so on were also tested. The results showed that the pervious floor coating had high permeability applicable to rainstorm environment, and good freezing resistance applicable to cold region.

Key words: polyurethane floor, solvent -free floor, pervious floor, permeability, freezing resistance
