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. © 2025 Elsevier Ltd.
