摘　　要：针对钢桥面铺装结构逐渐老龄化和车辆类型日益大型化、重型化,铺装层逐渐出现开裂、车辙、推移等耐久性问题,为减少病害产生,有必要研制一种新型钢桥面铺装结构,以提高铺装结构的使用寿命与耐久性。文中提出EA-10+ESMA-10的超高韧性铺装组合结构,通过高温试验、拉拔试验和三点梁疲劳试验,研究了超高韧性铺装组合结构的高温稳定性能、层间黏结性能和复合梁疲劳性能。结果表明EA-10+ESMA-10组合结构的高温抗车辙、层间黏结强度和抗疲劳性能均表现优异,在高温重载下具有良好的服役性,相应研究成果可为类似工程提供技术支撑。In response to the aging of steel bridge deck pavements and the increasing size and weight of vehicles,leading to durability issues such as cracking,rutting,and displacement in the pavement layers,it is necessary to develop a new type of steel bridge deck pavement structure to improve its service life and durability.This study proposes an ultra-high toughness pavement composite structure named EA-10+ESMA-10.Through high-temperature tests,pull-off tests,and three-point beam fatigue tests,the study investigates the high-temperature stability,interlayer bonding performance,and fatigue performance of the composite structure.The results show that the composite structure exhibits excellent high-temperature rutting resistance,interlayer bonding strength,and fatigue resistance.It demonstrates good serviceability under high-temperature and heavy-load conditions.The corresponding research findings provide technical support for similar engineering applications.
