摘要
目前沥青路面设计以应力为控制指标,使用高强度材料导致沥青路面早期破损严重。通过石灰岩AC-13级配疲劳试验分析,提出应变控制方式下沥青混合料的疲劳性能预估模型。
The early pavement design precedure are essentially based on taking stresses generated at all level in the pavement as an indicator for evaluating the pavement serviceability. If more rigid materials are used, failure problem after initially opening to traffic would be serious. In this paper, fatigue testing of limerock AC - 13 graded mixture is carried out, modulus of mixture has been presented for predicting fatigue performance using strain as a crisis indicator to determine pavement serviceability.
