优质的橡胶沥青应力吸收层作为一种高弹性、高变形、高粘度、不渗透的中间层,在具备较普通封层更优异的封水、粘结作用的同时,兼备普通封层所不具备的吸收半刚性基层所产生的反射裂缝部位的应力集中,从而达到防止、延缓和减少在沥青路面形成反射裂缝,进而达到延长路面使用寿命的效果。本文结合橡胶沥青应力吸收层在泗许高速公路的施工实践,总结了橡胶沥青应力吸收层的施工工艺,并就施工中存在的问题进行分析总结和探讨。
High-quality rubber asphalt stress absorption layer as a highly elastic, high deformation, high viscosity, impermeable intermediate layer, with more common sealing than the superior water seal, the role of both the ordinary sealing layer does not have Of the absorption of semi-rigid base layer of the reflection cracks generated by the stress concentration, so as to prevent, delay and reduce the formation of reflective cracks in the asphalt pavement, thereby extending the life of the road to extend the effect. In this paper, the construction process of rubber asphalt stress absorption layer in Si-Si expressway is summarized. The construction process of rubber asphalt stress-absorbing layer is summarized. The problems in construction are analyzed and discussed.
