摘　　要：低噪声沥青路面是降低城市交通噪音的主要手段之一。通过对沥青混凝土降噪模式的比较,确定采用声波的漫反射及相互干涉和弹性模式来设计低噪声路面。通过驻波法确定混合料组成的关键参数,根据这些参数确定的混合料配合比设计可以在城市道路及公路实际工程中应用。The low-noise asphalt pavement is one of the primary means of reducing urban traffic noise.By comparing different noise reduction modes,it is determined to use acoustic reflection,mutual interference and elastic model to design low noise pavement.Standing wave method is used to determine key parameters of composed mixture.According to these parameters,mixture grade is designed which is able to be applied in urban road and highway engineering.
