摘要
本文通过轮胎垂直振动衰减试验和轮胎/路面振动模拟试验,研究了橡胶颗粒分布层位对橡胶颗粒沥青路面降噪效果的影响。研究表明:橡胶颗粒沥青路面降噪效果最佳的分布层位为上面层,但是橡胶颗粒分布于下面层时的降噪效果与上面层相比相差甚微。如果侧重考虑路面的最基本路用性能,那么橡胶颗粒分布于上面层较好;如果侧重考虑路面的耐久性,橡胶颗粒分布于下面层较好。
This paper studies that Influencing on rubber particles＇ distributing layer for noise reduction effect of asphalt pavement by the experiment of the attenuation of vertical vibration and track simulation.The research shows that the top layer is the best distributing layer of the impact of the noise reduction,but the following layer has little difference with the top layer.Considering the basic pavement performance particularly,the property is better when rubber particles locate on the top layer.The focus to consider the durability of the pavement,it is better that rubber particles are located in the following.
