摘要
选择杭州市建国路和庆春路进行一般沥青路面和疏水性低噪声沥青路面降噪比较试验,结果表明在试验条件下采用疏水性低噪声路面在晴天气象条件的降噪效果Leq可达3.8～9.3dB,雨天气象条件的降噪效果Leq可达7.2～8.7dB,疏水性低噪声沥青路面降噪效果明显,并且在城市道路中控制适当的车速有利于减轻交通噪声。
A contrast test about common asphalt pavement and hydrophobic asphalt pavement with low noise was carried on,selecting Qingchun road and Jianguo road in Hangzhou as the objects.The results show that hydrophobic asphalt pavement with low noise has obvious effect on noise reduction.Leq noise reduction is up to 3.8 ～ 9.3 dB in sunny days and 7.2 ～ 8.7 dB in rainy days.The appropriate speed will help reduce traffic noise in urban road.
