双层大孔隙沥青路面在蒙山路的应用与性能分析

Application and Performance Analysis of Double-layer Macroporous Asphalt Pavement on Mengshan Road

结合蒙山路双层大孔隙沥青路面的实施,对其各项路用性能指标进行了测试,重点采用了声学材料阻抗管来测定大孔隙沥青混合料的吸声系数,同时对沥青路面的排水性能和抗滑性能进行了检测和评价。结果表明,双层大孔隙沥青路面的排水效率更高,动态摩擦因数优于普通密级配沥青路面的摩擦因数,具有较好的降噪效果。

Combined with the implementation of the double-layer asphalt pavement of Mengshan Road,this paper tests various pavement performance indexes.The acoustic material impedance tube is mainly used to measure the sound absorption coefficient of the asphalt mixture with large pores.At the same time,the drainage performance and anti-skid performance of the asphalt pavement are tested and evaluated.Results show that the surface of double-layer asphalt pavement with large pores has higher drainage efficiency,dynamic friction coefficient is better than that of ordinary dense-graded asphalt pavement and has better noise reduction effect.
