摘要： 随着汽车工业的发展和城市道路交通量的迅速增长，造成城市道路噪声的增加，给人民群众的日常生活和工作带来严重影响，城市道路沥青路面的降噪研究已为当务之急。为保证沥青路面的降噪效果，要求其路面的空隙率为15%-20%。因此对材料的级配组成、沥青结合料的性能、混合料的油石比、物理性能指标等都有严格的要求。采用试验的方法在不同的级配范围内进行多孔性沥青路面材料的配合比设计，为确定多孔性沥青路面材料的降噪性能提供依据。

Abstract: With automobile industrys development and urban traffic growth, traffic noise in urban areas increases rapidly, which brings the serious influence on the daily life and work for the residents. Therefore, noise reduction research of bituminous pavements of urban roads is urgent. In order to guarantee the noise reduction effect of the bituminous pavements, the porosity 15%~20% is required for the pavement. Therefore, the material gradation composition, bituminous binder's performance, the asphaltaggregate proportion, and the physical properties of the pavement must be controlled precisely. This article uses experimental method to carry on the design of mix proportion of the porous bituminous pavement material for different aggregate gradation to provide the basis for determination of the noise reduction performance for the porous bituminous pavement materials.

Key words: acoustics, porosity, bituminous pavement, asphalt mixture, mix proportion
