摘　　要：橡胶沥青应力吸收层在道路"白改黑"工程得到了广泛使用,这种结构层的功能特点主要有防反射裂缝、抗水毁以及粘结作用;通过研究各种应力吸收层的抗剪切强度、拉拔强度及疲劳性能,显示了橡胶沥青应力吸收层的优势,并利用实体工程介绍了橡胶沥青应力吸收层的设计方法。Stress absorbing layer of rubber asphalt has been widely used in the engineering of cement concrete pavement additionally paved with asphalt. It is mainly characterized by reflective crack prevention, water damage resistance and bonding effect. In this paper, the shear strength, pull strength and fatigue performance of various stress absorbing layers were studied to demonstrate the advantages; in addition, the method designing this layer of rubber asphalt was introduced with practical engineering.

关 键 词：橡胶沥青 应力吸收层 防反射裂缝 抗剪强度 拉拔强度 疲劳寿命
