Linear amplitude sweep (LAS) test is often used for fatigue characterization of asphalt binders. In this study, we propose a new technique based on the integration of Miner’s linear damage rule and LAS test data to determine the fatigue life of the asphalt binders. We tested eight asphalt binders with varying rheological properties for the proposed method. The results are compared with pseudotrain energy (PSE) based analysis, derived from the viscoelastic continuum damage (VECD) principle. We found that the proposed method gives comparable results with the PSE-based approach. The relationship between the number of cycles to failure \(N_{f}\) and strain amplitude \(\gamma _{p}\) obtained from the proposed approach is independent of any model fitting step, unlike the PSE-based approach. With the proposed method, the measured data can be directly used to estimate the fatigue life using a few simple steps, thus saving the time and effort required in the VECD-based analysis framework.

线性振幅扫描 (LAS) 测试通常用于沥青结合料的疲劳表征。在这项研究中，我们提出了一种基于 Miner 线性损伤规则和 LAS 测试数据集成的新技术，以确定沥青结合料的疲劳寿命。我们针对所提出的方法测试了具有不同流变特性的八种沥青粘合剂。将结果与基于粘弹性连续损伤 (VECD) 原理的基于伪列车能量 (PSE) 的分析进行比较。我们发现所提出的方法给出了与基于 PSE 的方法相当的结果。失效循环次数\(N_{f}\)与应变幅\(\gamma _{p}\)的关系与基于 PSE 的方法不同，从所提出的方法中获得的结果独立于任何模型拟合步骤。使用所提出的方法，测量数据可以通过几个简单的步骤直接用于估计疲劳寿命，从而节省了基于 VECD 的分析框架所需的时间和精力。
