摘　　要：本文研究了一种新型的开级配沥青磨耗层(OGFC)改性剂ATS,并通过实验测试了其改性效果。由于OGFC的孔隙率较大,易受外界环境的影响,因此要求采用的沥青具有耐久的握裹力、较强的粘着力及抗老化性能。本文在水稳定性、低温性能及动稳定度等方面对ATS进行了研究,并与传统改性剂TPS进行了对比。实验结果表明,通过ATS进行改性的OGFC混合料在各项性能表现上均优于TPS,具有更好的耐久性和稳定性,表明ATS是一种具有潜力的OGFC改性剂。This study investigates a new type of modifier for open-graded friction course(OGFC)called ATS,and evaluates its effects on OGFC performance through laboratory experiments.However,due to its high porosity,OGFC is easy to be affected by the external environment.Therefore,the asphalt binder used in OGFC should possess durable adhesion,strong cohesion,and anti-aging properties.The present study examines the water stability,low-temperature performance,and dynamic stability of the OGFC modified by ATS,and compares it with the traditional modifier TPS.The experimental results dem‐onstrate that the OGFC mixture modified by ATS outperforms TPS-modified OGFC in terms of durability and stability,indicating that ATS is a promising modifier for OGFC.
