| 摘 要： | 应力吸收膜可以有效阻止或延缓沥青路面出现反射裂缝的产生。应力吸收膜能够以微小的变形吸收和释放基层裂缝传递给面层的应力。为研究应力吸收膜防反射裂缝的效果,通过有限元软件对半刚性基层开裂时应力吸收膜及沥青面层的受力进行了分析。得出应力吸收膜对防止半刚性基层沥青路面非荷载型反射裂缝作用明显,应力吸收膜的模量越低越有利,应力吸收膜的厚度相对大时有利,应力吸收膜的泊松比指标对此项功能影响不大的结论。

| Abstract: | A stress absorbing membrane interlayer（SAMI） between the semi-rigid base and asphalt pavement could prevent the pavement from cracking effectively or at least postponing it because it can absorb or release the stress by tiny deformation.In order to study the effects of SAMI to the reflective cracking,this paper researched on infinite element and semi-rigid base.The conclusion is the lower the modulus of elasticity is,the deeper the layer is,the more effective it is to prevent the reflective cracking,and the poisson ratio take little effect on it. |
