摘　　要：反射裂缝是沥青路面的主要病害之一,而设置应力吸收层是预防和延缓反射裂缝的重要手段。介绍了4种主要应力吸收材料的组成、作用机理、国内外发展和应用现状,分析了其优缺点,并对应力吸收材料在我国的发展作了展望。Reflection cracks is recognized as one of the main hazards in asphalt pavements, and one of the important means of preventing and mitigating reflection cracks is using stress absorbing membrane interlayer. In this paper, the emphasis is the introduction of constituent, prevention mechanism, development and application of four kinds of stress absorbing materials, meanwhile their merits and defects are analyzed, and further development of stress absorbing materials is forecasted in China.

关 键 词：反射裂缝 应力吸收材料 土工合成材料 改性沥青
