With automobile industrys 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 asphaltaggregate 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.
