Changes in the properties of bitumen binders that occur as a result of aging have a huge impact on the durability of products produced from them. In particular, asphalt pavements, which constitute the most common use of petroleum bitumen, are susceptible to damage resulting from the increasing stiffness of the bitumen during its life cycle. Increased stiffness of asphalt pavements reduces the pavement resistance to low-temperature cracks and fatigue cracks, ultimately leading to the loss of their functional properties and the need for road repair. The rate of changes in bitumen properties is influenced by many factors, the most important of which are environmental conditions, technological parameters of binder processing, and physicochemical properties. The greatest impact on minimizing the adverse effect of aging is the use of bitumen suitably resistant to aging, and changing the technological parameters of its application. This article reviews the literature and standardized test methods of bitumen aging, with a focus on the methods that are most often used in practice, to evaluate the suitability of bitumen for use in road construction. The presented methods are limited to aging simulation. This mini-review presents the most important stages of aging procedures, their advantages and limitations, as identified by the authors of this publication for different types of bitumen. Moreover, the most important directions of developments in the field of new laboratory aging tests are highlighted. The suggestions are based on the industrial practice of the authors of this review, taking into account identified demands for quality control in the industry.
老化导致的沥青结合料性能变化对由其制成的产品耐久性有巨大影响。特别是，构成石油沥青最常见用途的沥青路面，在其生命周期中容易因沥青刚度增加而受损。沥青路面刚度增加会降低路面抵抗低温裂缝和疲劳裂缝的能力，最终导致其功能性能丧失并需要进行道路修复。沥青性能变化速率受许多因素影响，其中最重要的是环境条件、结合料加工工艺参数和物理化学性质。对最小化老化不利影响影响最大的是使用具有适当抗老化性的沥青，并改变其应用工艺参数。本文综述了沥青老化的文献和标准化测试方法，重点关注实践中最常用的方法，以评估沥青用于道路建设的适用性。所介绍的方法仅限于老化模拟。本小型综述介绍了老化程序的最重要阶段、它们的优点和局限性，这些是本出版物的作者针对不同类型沥青确定的。此外，还突出了新的实验室老化测试领域最重要的发展方向。这些建议基于本综述作者的行业实践，并考虑到行业中确定的质量控制要求。
