摘要
为构建基于多指标的沥青路面设计方法,需要针对沥青路面的低温缩裂提出使用性能分析模型。因此,依据东北地区公路沥青路面低温开裂状况的实际调查,以沥青路面的开裂指数为设计指标,基于残差分析方法构建沥青路面低温开裂量的经验预估模型,可供季冻区沥青路面结构设计参考。
To form one kind of asphalt pavement design method based on multi-index,it is needed to put forward a usability analytical model of asphalt pavement in the condition of low temperature cracking.Therefore,on the basis of actual survey of asphalt pavement low temperature cracking status in Northeast China Region,an experience-based predicting model is set up by residual analysis method to predict low temperature cracking quantity of asphalt pavement using cracking index of asphalt pavement as a design index,which can be a reference for asphalt pavement design in seasonally frozen region.
