摘要
RAP材料的加入显著影响了沥青混合料的力学参数,因此直接参考规范取值是不合理的做法,系统研究了RAP掺量对热再生混合料抗压回弹模量、动态模量以及劈裂强度的影响,建立了热再生混合料抗压回弹模量与RAP掺量之间的回归关系式,并推荐了不同RAP掺量热再生混合料合理的模量取值范围,为沥青路面热再生混合料路面设计提供参考依据。
The join of RAP material significantly affects the mechanical parameters of asphalt mixture,so a direct reference specification values are unreasonable,this article systematically studied the affect of RAP content on compression modulus,dynamic modulus and splitting strength of hot recycled mixture,established regression equation between the compressive modulus of resilience and RAP content,And recommended the reasonable mix modulus ranges under different RAP content. The result of research can provide a reference for the pavement design of hot recycle mixture.
