低噪声路面研究进展

交通噪声污染严重影响了人们的生活和环境。现分别对水泥低噪声路面、沥青低噪声路面和多孔弹性低噪声路面的研究进行了综述。既有研究表明,水泥低噪声路面和沥青低噪声路面可以降低噪声3~5 dB,但是多孔结构会导致混合料强度的降低,以及施工工艺的复杂化和能耗的加剧。多孔弹性低噪声路面降噪性能可以达到10 dB以上,但是较差的抗剥落性能导致其使用寿命较短。因此,为了满足人们对城市环境日益增长的要求,有必要对如今的低噪声路面进行深入研究,为建设耐久性好且降噪能力优异的降噪路面提供参考。

Research Progress of Low Noise Pavement

Traffic noise pollution seriously affects people's life and environment.This paper summarizeds the research of low noise cement pavements,low noise asphalt pavement and porous elastic low noise pavement.Existing research showed that cement low noise pavement and asphalt low noise pavement could reduce noise by 3-5db,but porous structure could lead to the decrease of mixture strength,the complexity of construction technology and the aggravation of energy consumption.However,the anti-spalling performance of porous pavement was poor due to its short service life.Therefore,to meet the growing requirements of urban environment,it was necessary to conduct in-depth research on the low-noise pavement,so as to provide reference for the construction of noise reduction pavement with good durability and excellent noise reduction ability.
