橡胶沥青应力吸收层(AR-SAMI)对沥青路面荷载应力响应的影响探析

Analysis on Influence of Rubber Asphalt Stress Absorbing Layer on Load Stress of Asphalt Pavement

AR-SAMI以其优良的应力吸收效果、施工简单及速度快等特点在国外得到广泛的应用。利用有限元软件(ABAQUS)建立了沥青路面典型结构的有限元模型,通过有限元模拟AR-SAMI防治反射裂缝的效果,并通过工程实例加以论证,为今后AR-SAMI提供技术指导。AR-SAMI能起到有效吸收应力的作用,对防治沥青路面的反射裂缝起到较好的作用。

The rubber asphalt stress absorbing layer(AR-SAMI) is widely used abroad because of its good stress absorbing effect, simple construction and fast speed. The finite element software(ABAQUS) is used to establish the finite element model of typical structure of asphalt pavement. The effect of AR-SAMI to prevent the reflection crack is simulated by the finite element, and is demonstrated through the engineering cases in order to provide the technical guidance for AR-SAMI in the future. The AR-SAMI can play the role to effectively absorb the stress, and can play the better role to prevent the reflection crack of asphalt pavement.
