Low-noise Asphalt Pavement

It is a serious problem that traffic noise affects people. Paving low-noise asphalt pavement is a main method to reduce pavement noise. Now, the effect of reducing noise can reach expected aim to traditional low-noise asphalt pavement,but it's durability is worse.This paper studied main factors of porous asphalt pavement reducing noise and mechanism of reducing noise. Ba(?)d on overseas and domestic information, this paper designed traditional low-noise asphalt mix and new-improved low-noise asphalt mix. According to new-improved low-noise asphalt mix design method,test road was paved from Ji-nan to Liao-cheng freeway, and the construction method was researched to low-noise asphalt mix.
