The invention discloses a macroporous polyurethane macadam mixture which is called PPM for short.The mixture is prepared from, by mass, 100 parts of macadam and 3-5 parts of a polyurethane adhesive.The macadam comprises single-particle-diameter marble, granite, limestone and basalt.The particle diameter of the macadam is 2-3 mm, 3-5 mm, 4-6 mm, 6-8 mm or 8-10 mm.The single-particle-diameter or discontinuous-particle-diameter macadam with the particle diameter being 2-10 mm is mixed with the polyurethane adhesive so that a road surface material with the porosity being 15-30% can be formed, and water permeability and air permeability are good.Underground water can be supplied.Water and nutrient required by animals and plants below the ground can be provided, and temperature and humidity of surrounding environments are improved.The heat island effect is relieved, the phenomena that a vehicle slides when running on a road surface and rainwater splashes are avoided, the road surface is not frozen after raining in winter, and traffic hidden hazards are reduced.Acoustic impedance of the road surface can be changed, vehicle noise is absorbed, and noise pollution is reduced.
