摘要
对杭州市疏水性沥青路面改造前后的5条道路交通噪声进行了监测，并时临路居民交通噪声烦恼度进行了社会调查。结果表明，5条道路疏水性沥青路面改造后比改造前各固定监测点Leq降低了0.2～8．7dB，各条道路平均等效声级值降低了2.4～6．0dB，客观上疏水性沥青路面降噪效果明显；改造后临路居民对交通噪声的烦恼度社会调查中“烦恼和非常烦恼”的比例在各种情形下较改造前均有较大降低，主观上临路居民对噪声的烦恼感受明显降低。
Traffic noises of five roads in Hangzhou were monitored before and after hydrophobic asphalt pavement reconstruction, and traffic noise annoyance from the residents who lived near roads was surveyed. A contrast of after reconstruction with before reconstruction showed that Leq reduced 0.2 - 8.7 dB and average equivalent sound level reduced 2.4 - 6.0 dB, which indicated that hydrophobic asphalt pavement had obvious noise reduction effect. The level of traffic noise annoyance from residents in social surveys was reduced significantly.
