Faulting is one of the primary distresses in Jointed Concrete Pavement (JCP), due to the combined effects of ambient environmental factors, load transfer and repeated traffic loads. The combined effects induce the various stages of the increasing size of faulting. It is found that the earliest progression of faulting in the pre-erosion stage is caused by the plastic deformation of the base layer. An existing deformation model was adapted for the development of a faulting prediction model. In this study, a new mechanistic-empirical faulting model was proposed to characterize the relationship between the amounts of faulting, mostly contributed by the plastic deformation of base layers, and traffic repetitions characterized by the axle load distribution which displays percentages of axles with respect to the non-repeating load levels. To incorporate the effect of the load distributions into the model, a consistent and reasonably accurate set of mechanics-based equations were adopted to determine the average state of stress in the base layers. By using Long Term Pavement Performance (LTPP) data, the model is verified to be valid and considerably accurate. The model parameters are statistically calibrated with pavement performance-related factors for better implementation of the model.

由于周围环境因素，荷载传递和反复的交通荷载共同作用，断层是关节混凝土路面（JCP）的主要问题之一。组合效应导致断层增大的各个阶段。发现在侵蚀前阶段的断层最早发展是由于基层的塑性变形引起的。现有的变形模型适用于断层预测模型的开发。在这项研究中，提出了一种新的机械-经验断层模型，以表征主要由基层塑性变形引起的断层数量与以轴荷分布为特征的交通重复之间的关系，轴荷分布显示轴相对于轴的百分比非重复负载水平。为了将载荷分布的影响纳入模型，采用了一套一致且合理准确的基于力学的方程式来确定基础层的平均应力状态。通过使用长期路面性能（LTPP）数据，该模型被验证为有效且相当准确。使用与路面性能相关的因素对模型参数进行统计校准，以更好地实施模型。
