ELASTIC PAVING MATERIAL FOR LOW NOISE AND EXECUTION OF ELASTIC PAVING FOR LOW NOISE

摘要

PROBLEM TO BE SOLVED: To provide an elastic paving material for a low noise having a structure in which hard aggregate is bonded to elastic aggregate with a urethane binder, in relating to paving applied to a driveway and characterized by a low noise and a vibration-reducing effect caused by the elasticity, air permeability and noise-absorbing property. SOLUTION: This elastic paving material for a low noise is composed of hard aggregate, elastic aggregate and a urethane binder bonding them, and a content of the hard aggregate in the whole aggregate is 10-75 vol.% and a two pack-type urethane binder is used as the urethane binder.
