Abstract

To further improve the quality of bridge deck asphalt pavement (BDAP) and advance the level of bridge industrialization, a future sustainable prefabricated BDAP structure system is developed and its corresponding joint strengthening approach using the geosynthetics non-woven geotextile fabric (NWGF) is proposed for its assembly connection. Moreover, direct three-point bending and bending fatigue tests are conducted to evaluate the joint interface crack resistance performance, and the direct shear and pullout tests are implemented to assess interlayer bonding performance of the structure system after utilizing NWGF. Results show that the use of NWGF could effectively delay the joint interface cracking of prefabricated BDAP, significantly enhance the fatigue cracking life of the composite structure, and also be beneficial to improving the fracture toughness of the interlayer bonding. This research provides the joint scheme for assembly connection and corresponding joint strengthening approach, which promises the application of future sustainable prefabricated BDAP.

为进一步提高桥面沥青路面（BDAP）的质量，提升桥梁工业化水平，本研究开发了一种未来可持续发展的预制桥面沥青路面结构体系，并提出了相应的接缝加固方法，即采用土工合成材料无纺土工织物（NWGF）进行装配连接。此外，还进行了直接三点弯曲和弯曲疲劳试验，以评估连接界面的抗裂性能，并进行了直接剪切和拉拔试验，以评估使用 NWGF 后结构系统的层间粘结性能。结果表明，NWGF 的使用能有效延缓预制北斗卫星导航系统的连接界面开裂，显著提高复合材料结构的疲劳开裂寿命，并有利于提高层间粘结的断裂韧性。该研究提供了装配连接的接缝方案和相应的接缝加固方法，为未来可持续预制 BDAP 的应用提供了可能。

期刊介绍： Transportation Geotechnics is a journal dedicated to publishing high-quality, theoretical, and applied papers that cover all facets of geotechnics for transportation infrastructure such as roads, highways, railways, underground railways, airfields, and waterways. The journal places a special emphasis on case studies that present original work relevant to the sustainable construction of transportation infrastructure. The scope of topics it addresses includes the geotechnical properties of geomaterials for sustainable and rational design and construction, the behavior of compacted and stabilized geomaterials, the use of geosynthetics and reinforcement in constructed layers and interlayers, ground improvement and slope stability for transportation infrastructures, compaction technology and management, maintenance technology, the impact of climate, embankments for highways and high-speed trains, transition zones, dredging, underwater geotechnics for infrastructure purposes, and the modeling of multi-layered structures and supporting ground under dynamic and repeated loads.
