Open-graded drainage colored pavement capable of absorbing automobile exhaust
The invention discloses an open-graded drainage colored double-layer porous drainage pavement capable of absorbing the automobile exhaust. The double-layer pavement is of a composite open-graded drainage abrasion structure composed of a small-pore open-graded pavement structure at the upper layer and a large-pore open-graded pavement structure at the lower layer. The upper-layer pavement structure is formed by mixing cementing materials and an open-graded fine particle mixture. The cementing materials include colored resin, epoxy asphalt and nanometer titanium dioxide. The added nanometer titanium dioxide has the functions of purifying the automobile exhaust, absorbing the exhaust discharged by the automobile and reducing the concentrations of CO and NOx compounds in cities. By applying the colored pavement, the heat absorption coefficient of the pavement surface layer is reduced, the temperature of the asphalt pavement is lowered by 2 DEG C approximately, and the heat island effect of cities is favorably alleviated. The fine-grain surface layer of the double-layer porous drainage pavement has better noise reduction effects, dust entering the surface layer is more easily removed by the pumping effect of wheels, and thus the self-cleaning effect is better; the drainage asphalt pavement has very obvious noise reduction effects under the condition of rainy days.
