Abstract

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.
