Abstract (en)

The present invention is a reduced noise elastic pavement material which is applied to roadways and has a noise reducing effect and a vibration reducing effect due to elasticity, air permeability, and sound absorption. The reduced noise elastic pavement material has a structure in which a hard aggregate and an elastic aggregate are bonded together by a urethane binder. More specifically, the reduced noise elastic pavement material is formed by a hard aggregate, an elastic aggregate, and a urethane binder which bonds the hard aggregate and the elastic aggregate together, in which the hard aggregate is 10 to 75 % by volume of a total volume of the hard aggregate and the elastic aggregate, and a two-component urethane binder is used as the urethane binder. <IMAGE>
