为研究胶粉改性沥青混合料与 SBS 改性沥青混合料路面的降噪效果，利用 AWA6270型声级仪进行噪声检测，通过对轻重两种车型在不同车速下的整车噪声检测、车室内噪声检测、怠速下噪声检测3个实验的结果进行分析，结果表明：噪声声级随着车速的增加而增加，且轻型轿车的噪声声级与车速呈线性关系；2种车型的整车噪声最大，其次是怠速噪声，最弱的是车内噪声；胶粉改性沥青路面在降噪方面的性能优于 SBS 改性沥青路面，尤其是对怠速状态下行驶的汽车。

In order to study the effect of noise reduction about mixture pavement of rubber powder modified asphalt and SBS modified asphalt pavement,sound level meter-AWA6270 was using for noise detection.Based on the analysis of noise detection,vehicle interior noise detection and idle noise detec-tion under different automobiles and different speed,result shows that:noise level increases with the speed,and that of light cars increases linearly;noise of whole automobiles is the largest,the next is idle noise;rubber modified asphalt pavement performance is better than SBS modified asphalt in noise reduc-tion especially for the automobiles with idle noise.
