摘　　要：沥青混合料是一种热流变简单材料,沥青路面的开裂、车辙、疲劳等破坏问题都与沥青混合料的粘弹性特性有关,因此沥青混合料粘弹性参数的确定对开展沥青混合料及沥青路面研究尤为重要。以橡胶沥青路面AR-AC13为例,通过试验和理论计算确定橡胶沥青路面粘弹性参数,确立本构模型,为橡胶沥青路面进一步力学研究提供依据。Asphalt mixture is a kind of thermorheologically simple material. The diseases of asphalt pavement, such as cracking, rutting and fatigue failure, are related to viscoelasticity of asphalt mixture.Therefore, it is particularly important to determine the viscoelastic parameters of asphalt mixture for carrying out the study of asphalt mixture and asphalt pavement. According to the rubber asphalt pavement AR-AC13,the experiment and the theoretical calculation can determine the viscoelastic parameters of rubber asphalt pavement, and establish the constitutive model, which can provide the basis for further mechanics study of rubber asphalt pavement.
