通过全面的文献综述、交通机构调查和现场观察，收集了关于模块化桥梁伸缩缝系统的使用性能和耐久性的数据。讨论了典型的使用寿命和期望的使用寿命目标。最大的运动和旋转的要求是相对于三个轴。性能和耐久性问题包括可追溯到不良设计和/或安装、弹性体部件的磨损和撕裂以及金属部件的紧固件松动和疲劳开裂的问题。疲劳裂纹已在以前的研究中得到解决。指导设计，详细说明，规格，安装和维护进行了讨论，这应该减少在第一组的问题。弹性体部件和紧固件的问题最好通过对作为一个系统的模块化桥梁接头系统进行性能测试来解决。两个系统的性能测试，一个开放的运动/振动测试，和密封推出测试建议…
Data regarding service performance and durability of modular bridge expansion joint systems were gathered through a comprehensive literature review, survey of transportation agencies, and field observations. Typical service life and desired service life targets are discussed. Maximum movement and rotation demands are given with respect to three axes. Performance and durability problems include problems that can be traced to poor design and/or installation, wear and tear of elastomeric parts, and fastener loosening and fatigue cracking of the metal parts. Fatigue cracking has been addressed in previous research. Guidance on design, detailing, specifications, installation, and maintenance is discussed, which should reduce the problems in the first group. Problems with the elastomeric parts and fasteners are best addressed through performance tests on the modular bridge joint systems as a system. Two system performance tests, an opening movement/vibration test, and a seal push-out test are suggested for the ...
