摘　　要：分析我国沥青路面设计方法中存在的静态参数与动态指标配套使用,及由于弯沉综合修正系数引起的不合理现象,引入材料的动态参数计算沥青路面路表弯沉,并与路表实测弯沉进行比较,使沥青路面设计中设计参数与控制指标状态一致,并去除弯沉综合修正系数及其不当影响。The active asphalt pavement design system is based on elastic laminar theoryBut the static parameters and dynamic indicators are used there simultaneouslyAlso there is an abnormality which is caused by the use of synthetical correction factor of deflectionThe objective of this thesis is to research on the dynamic characteristics of materials,calculate deflection with dynamic parameters (dynamic modulus) and compare it with the measured deflection,so that to eliminate the use of synthetical correction factor of deflection and those abnormalities in asphalt pavement design method

关 键 词：弯沉综合修正系数 沥青路面 设计方法 动态模量
