沥青稳定基层混合料设计方法研究

Mixture Design Method of Asphalt stabilized Base Course

本文针对沥青稳定基层的性能特点提出了以混合料内部粘结力最佳为目标的混合料配合比设计方法 ,利用抗压强度试验和劈裂强度试验这 2个常规试验方法的组合进行了配合比设计 ,并通过变形性能测试和疲劳性能测试验证了设计方法的正确性 .研究表明 ,采用最佳粘结力为设计目标 ,可以兼顾变形和疲劳性能 。

Based on the property of stabilized base course, a new mixture design method based on the greatest adhesion inside is put forward. Mixture component design can be finished through general methods of compression test and indirect tension test, and can be verified through tests of deformation property and fatigue property.The results show that this method can combine both deformation and fatigue, and relate the mixture design with pavement performance.
