Traffic Noise Reducing Technology using RSBS(Radial type SBS) Modifiers Into Double Layer Pavement

RSBS(Radial type SBS)를 이용한 복층포장구조에 의해 도로교통소음을 저감하는 기술

This is traffic noise reducing technology with higher porosity and durability by using small aggregate in upper layer and big aggregate in lower layer utilizing RSBS modifier. We can reduce average 9dB(A) of traffic noise compare to normal pavement by double layer structure with higher durability using small gap over bigger gap. Also, it increases a porosity more than 22% with more durability by RSBS modifier.
