摘　　要：疲劳损伤理论因其能较好地反映沥青路面疲劳破坏现象的本质,有望明确路面使用性能与路面结构、使用年限及使用环境之间的关系而被国内外众多专家学者所关注,并围绕其在沥青路面领域的研究与应用开展了大量工作。但就疲劳损伤理论目前的相关研究现状来看,仍有较多人对该理论的基本内容不甚了解,且该理论在沥青路面领域取得的大量成果也未得系统梳理,在一定程度上阻碍了该理论在沥青路面领域的应用和发展。鉴于此,本研究从疲劳损伤力学基本理论和沥青路面疲劳损伤理论的研究现状,以及该理论在研究与应用中存在问题的分析等方面入手,对沥青路面疲劳损伤理论进行了系统综述。简要介绍了该理论的基本内容——损伤变量、损伤演化方程、损伤本构方程和损伤场求解,并对其基本内容的相关现状和问题进行了分析。建议后续研究应在沥青混合料三维损伤-本构关系,能够体现混合料黏弹特性、温度敏感、加载速率敏感等特点的损伤演化方程,路面结构黏弹性分析,解析法求解损伤场及细观和大规模数值计算等方面投入更多精力,以求促进该理论在沥青路面领域的发展和进步。Fatigue damage theory now is paid more attention by many domestic and foreign experts because of its ability to better reflect the essence of fatigue damage of asphalt pavement,and is expected to clarify the relationship of pavement performance with its structure,service life and service environment.However,as far as the current research status of the fatigue damage theory is concerned,there are still many people who do not understand the basic content of the theory,and the large number of results obtained by the theory in the asphalt pavement field have not been systematically summarized,it hinders the application and development of this theory in the asphalt pavement field to a certain extent.In view of this,starting with the basic theory of fatigue damage mechanics and the research status of asphalt pavement fatigue damage theory,as well as the analysis of the problems in the research and application of the theories,the asphalt pavement fatigue damage theory is systematically summarized.The basic contents of the theory,i.e.,damage variables,damage evolution equation,damage constitutive equation and damage field solution,are briefly introduced,and the related status and problems of the basic contents is analysed.It is suggested that the further research should focus on the 3 D damage-constitutive relationship of asphalt mixture,the damage evolution equation that can reflect the viscoelastic properties of the mixture,the temperature sensitivity and the loading rate sensitivity,the viscoelastic analysis of the pavement structure,the analytical method to solve the damage field,and the mesoscopic and large-scale numerical calculations,etc.to promote the development and progress of this theory in the field of asphalt pavement.
