Research and Application of Drainage Noise Reduction Asphalt Mixture SMAp
With the acceleration of urbanization and the increase in the number of road vehicles,road noise and drainage problems have become important factors affecting the quality of urban life.There is an urgent need to develop new asphalt mixtures to address them.As a new type of asphalt,the unique structural and material characteristics of drainage and noise reduction asphalt mixture endow it with excellent drainage and noise reduction performance.It can effectively discharge rainwater from the road surface,improve traffic safety,alleviate the pressure on urban drainage systems,and reduce the air pumping effect between the road surface and car tires,thereby reducing vehicle noise pollution.Based on this,this article combines the Wuyue expressway project to explore the research and development technology and application methods of drainage noise reduction asphalt mixture SMAp,aiming to provide reference for technical personnel.
