基于空隙模型的大空隙沥青混合料设计

摘要

Void rate has a great influence on permeability and mechanic property of porous asphalt mixture. Permeability pavement may select adaptive void rate according to requirement. Target void rate obtained in void model can be used to design mixture ratio. The result indicate that target void rate obtained in void model can be used to guide mixture ratio design, which provide an efficient and accurate method for traditional design.%空隙率的大小对大空隙沥青混合料的渗透性及力学性能具有很大影响,透水铺面应根据用途选择合适的空隙率,在一定的水头(降雨强度)下利用空隙模型确定的目标空隙率进行混合料配合比设计.结果表明,空隙模型确定的目标空隙率可为混合料的配合比设计提供理论指导,提高了传统设计方法的工作效率和准确性.
