摘要
空隙率对沥青混合科技术性能的影响主要有以下几个方面：抗弯回弹模量、疲劳强度及水稳定性均随空隙率的增大而减小；透水系数与摩擦系数随空隙率增大而增大；空隙率小于８～１０％时，随着空隙率的增大，低温蠕变速率有增大趋势；车辙动稳定度与空隙率之间呈抛物线变化，即空隙率约在８％左右时，动稳定度出现峰值。
Influence of void content of asphalt aggregate mixture on its technical Characteristics-with increase of value of void content,values of bending tensile return elasticty module,strength of fatique and water tolerance have been reduced; with increase of value of void content,values of water permeability coefficient and friction factor have been increased too; When value of void content was less than 8% ￣10%,creep rate at low temperature has been increased,with increase of value of void content. Form curve of dynamic stability of asphalt aggregate mixture got in the Rutting test at different void content was a parabola-highest point has been presented in the curve of dynamic stability,when value of void content was about 8%.
