Description
Summary:Low-noise pavement can efficiently reduce the tire–road noise and improve the driving experience of passengers and life quality of residents along the line. Porous elastic road surface (PERS) is a type of low-noise pavement with excellent performance. This study summarizes the research status and analyzes the development trend of PERS. The research results show that PERS has a large elastic deformation capacity and a large porosity, thereby achieving elastic vibration damping and porous sound absorption. The effect is an effective way to fundamentally solve the current traffic noise problem. However, the lack of relevant research in the design theory of composite material composition, noise reduction function evaluation test method, and index system is a major factor that restricts the breakthrough of PERS in technical difficulties and the achievement of large scale engineering applications.
