浅析降低水泥混凝土路面噪声的措施

Analysis on the measures to reduce the noise of cement concrete pavement

基于对水泥混凝土路面—轮胎相互作用时产生的泵吸作用、振动作用、空气动力特性等噪声形成机理和相关影响因素的分析,指出降低水泥混凝土路面噪声可以从噪声源和传播途径方面着手,通过改变路面结构和改进施工工艺等措施,能够降低水泥混凝土路面的噪声。

Based upon analysis of the pumping action, vibration, aerodynamic characteristics and other noises＇ formation mechanism caused by interaction between cement concrete pavement ane tyre and related influencing factors some measures to reduce the noises of cement concrete pavement are proposed. Author points out from two aspects： noise source and propagation means noise of cement concrete pavement can be reduced through changing the structure of pavement, improving construction technology and other measures.
