| 摘 要： | 沥青路面的结构行为方程为基于性能的沥青路面结构设计方法奠定了良好的理论基础,但先前的研究仅较好地考虑了荷载、环境和结构等因素对沥青路面使用性能的影响,而对材料因素的影响考虑得较为粗略。鉴于材料影响的复杂性,论文从较为宏观的角度通过改性沥青和普通沥青结构行为方程和现场疲劳方程的建立给出改性沥青影响系数与改性-普通沥青寿命比值的关系,从而利用此关系以及通过试验获得的改性沥青和普通沥青混凝土的疲劳方程即可确定结构行为方程中的材料影响系数。

| Abstract: | The structural behavior equation has provided sufficient theoretical base for the asphalt pavement design method based on(performance).However,in the previous research only the loading,environmental and structural factors have been taken into account,the influence of materials hasn't been fully considered.Because of the complex influence of materials,the asphalt concrete and modified(asphalt) concrete structural behavior equation and field fatigue equation are developed,the relationship between the influence factors of modified asphalt binder and the ratio between the life of asphalt binder and modified binder provided.Depending on this relationship,(employing) the fatigue equation of asphalt binder and modified binder determined in the lab,the material influence(factors) can be(determined) in the structural behavior equation. |
