摘　　要：为评价花岗岩沥青路面结构力学性能,采用AC-10上面层加AC-16下面层组合的复合结构,基于一种基质沥青和5种不同抗剥落措施,进行了花岗岩沥青混合料复合结构的蠕变试验和动态模量试验。分析了不同方案在不同温度下结构的蠕变规律和混合料结构的动态模量,以及在多种加载频率下混合料的动态模量,对比分析了不同抗剥落措施对花岗岩沥青混合料力学性能的影响,为花岗岩在沥青路面中的应用提供了依据。In order to evaluate the mechanical properties of granite asphalt pavement structure,this study used a composite structure consisting of AC-10 upper layer and AC-16 lower layer.Based on a matrix asphalt and five different anti-stripping measures,creep tests and dynamic modulus tests were conducted on the composite structure of granite asphalt mixture.The creep laws of the structure under different schemes and temperatures,the dynamic modulus of the mixture structure,and the dynamic modulus of the mixture under various loading frequencies were analyzed.The influence of different anti-stripping measures on the mechanical properties of granite asphalt mixture was compared and analyzed,providing a basis for the application of granite in asphalt pavement.
