应力吸收层一般设置在沥青面层与水泥混凝土路面板之间,可分散水泥混凝土路面板接缝或裂缝处外荷载的集中应力,从而延缓甚至阻止沥青面层反射裂缝的产生。目前应力吸收层技术主要有采用改性沥青混合料应力吸收层、层布法应力吸收层、复合式应力吸收夹层、土工合成材料、同步碎石过渡层等。 The stress absorption layer is generally arranged between the asphalt surface layer and the cement concrete pavement slab to disperse the concentrated stress of the joints or crevices of the cement concrete pavement slab to delay or even prevent the reflection cracking of the asphalt surface layer. At present, stress absorption layer technology mainly adopts modified asphalt mixture stress absorption layer, layer cloth stress absorption layer, composite stress absorption interlayer, geosynthetics, synchronous gravel transition layer.
