Abstract
Road traffic noise is a harmful environmental pollutant that affects public health. Reducing the tire pavement noise by appropriate design of a durable pavement may reduce the road traffic, case study shows result shows that reducing the nominal aggregate size (NMAS) from 19.0mm to smaller value had a noticeable impact on the perceived noise from car traffic, the incorporation of seashell in OGAC (open graded asphalt concrete) can reduce the tire pavement noise by low frequencies. It has been observed also that rigid pavement makes more noise than flexible pavement.
