摘　　要：为了提升城市道路交通的排水降噪效果,本研究主要在不同基层体系下对双层排水降噪沥青面粘附层结构进行设计。沥青的添加量对混合料的级配具有重要影响,采用依次增加0.5%沥青的方式对混合料进行拌制。为提升混合料的耐老化性能,结合目标配合比试验确定沥青的最佳用量为±0.3%。双层排水降噪路面结构在使用过程中,对原有路面结构状态不产生影响,并且可达到排水降噪的效果。In order to improve the drainage and noise reduction effect of urban road traffic,this study mainly de⁃signs the structure of double-layer drainage and noise reduction asphalt surface under different base systems.The amount of asphalt has an important influence on the gradation of the mixture.The mixture is mixed by adding 0.5%asphalt sequentially.In order to improve the aging resistance of the mixture,combined with the target mixture ratio test,the optimal amount of asphalt was determined to be±0.3%.The double-layer drainage and noise reduction pavement structure has no influence on the original pavement structure,and can achieve the effect of drainage and noise reduction.
