提出了一种粘弹性细观力学模型来预测沥青混凝土的动弹性模量，并研究了沥青胶浆与集料之间的界面缺陷对沥青混凝土整体粘弹性特性的影响。引入线性弹簧层模型来模拟界面缺陷。基于有效介质理论，通过两个等效过程建立了粘弹性细观力学模型。将预测结果与已有的实验数据进行了比较，验证了所提出的理论框架。结果表明，该模型具有较好的预测交流动力模数的能力。利用所建立的模型，讨论了界面效应对交流动力模数的影响。结果表明，界面粘结强度对AC的整体力学性能有重要影响，要充分发挥集料增强的潜力，必须不断提高表面官能化程度。
A viscoelastic micromechanical model is presented to predict the dynamic modulus of asphalt concrete (AC) and investigate the effect of imperfect interface between asphalt mastic and aggregates on the overall viscoelastic characteristics of AC. The linear spring layer model is introduced to simulate the interface imperfection. Based on the effective medium theory, the viscoelastic micromechanical model is developed by two equivalence processes. The present prediction is compared with available experimental data to verify the developed framework. It is found that the proposed model has the capability to predict the dynamic modulus of AC. Interface effect on the dynamic modulus of AC is discussed using the developed model. It is shown that the interfacial bonding strength has a significant influence on the global mechanical performance of AC, and that continued improvement in surface functionalization is necessary to realize the full potential of aggregates reinforcement.
