| Abstract: | 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. |
