长期以来，水分被认为是沥青路面过早降解的重要因素。许多研究已经进行收集，描述和测量的沥青混合料的水敏感性。其中大多数旨在通过实地数据的目视观察或比较实验室试验，对水分损害进行比较测量。本文提出的研究是正在进行的研究工作的一部分，远离这种比较或经验的措施，水分引起的沥青材料的损坏，并通过一个全面的能源为基础的计算框架，开发一个基本的方法。这样的框架将能够在给定的环境和交通负荷下对沥青路面中发生的故障模式进行现实的预测和时间评估，所述故障模式可以是车辙、开裂、松散或其任何组合或表现。本文讨论了基本的水分引起的损伤参数，并证明了发展的模型。
Moisture has for a long time been recognized as a serious contributor to premature degradation of asphaltic pavements. Many studies have been performed to collect, describe and measure the moisture susceptibility of asphaltic mixes. Most of these aimed at a comparative measure of moisture damage, either via visual observations from field data or comparative laboratory tests. The research presented in this paper is part of an ongoing research effort to move away from such comparative or empirical measures of moisture induced damage of asphaltic materials and develop a fundamental approach via a comprehensive energy based computational framework. Such a framework would enable realistic predictions and time assessment of the failure pattern occurring in an asphaltic pavement under the given environmental and traffic loading, which could be rutting, cracking, raveling or any combination or manifestation thereof. The paper discusses the fundamental moisture induced damage parameters and demonstrates the developed model.
