摘要
利用声学的原理,从吸声系数与多孔隙沥青混合料结构之间关系的角度,论述了多孔隙低噪声沥青路面的降噪机理,分析了沥青路面混合料的孔隙率、混合料的最大粒径以及路面厚度对沥青路面的降噪效果的影响程度。
In this paper, the reduced noise mechanism of low-noise asphalt pavement are discussed, based on the relationship between sound-absorbing coefficient and porous asphalt mixture by means of principle of acoustics. Discussion is made on the porosity of asphalt minture, on the maximum grain size and the effects of the thickness of pavement on louering the noisy.
