Abstract

This study conducts a rigorous analysis of the moisture diffusion mechanism that undermines the adhesive layer of epoxy asphalt (EA) pavement on steel bridge decks, thereby fostering latent distresses. Furthermore, a novel and highly efficacious approach for detecting these concealed distresses is introduced. The findings of water vapor permeability tests conclusively reveal that the moisture diffusion coefficients of the upper and lower layers of the EA pavement stand at 0.1238 mm2/s and 0.0879 mm2/s, respectively, highlighting this disparity as the primary trigger for concealed issues like pavement delamination and swelling. Leveraging the combined capabilities of three-dimensional ground-penetrating radar (3D-GPR) and infrared thermography, this research reliably detects, identifies, and pinpoints concealed defects at three strategic locations on the steel bridge deck. The integration of these two technologies has exhibited remarkable proficiency in identifying concealed damages. Consequently, this study lays a substantial foundation for evaluating and detecting concealed distress in EA pavements atop steel bridge decks.

利用无损检测技术研究钢桥面环氧沥青铺装在湿气扩散条件下隐藏缺陷的机理
本研究对破坏钢桥面环氧沥青(EA)铺装粘合层、从而产生隐性损伤的湿气扩散机制进行了严格分析。此外,研究还介绍了一种新型、高效的方法来检测这些隐蔽性损伤。水蒸气渗透性测试结果明确显示,EA 路面上层和下层的湿气扩散系数分别为 0.1238 mm2/s 和 0.0879 mm2/s,这一差异是导致路面分层和膨胀等隐性问题的主要诱因。利用三维探地雷达 (3D-GPR) 和红外热成像技术的综合能力,这项研究可靠地检测、识别并精确定位了钢桥面上三个战略位置的隐蔽缺陷。这两项技术的结合在识别隐蔽损坏方面表现出了卓越的能力。因此,这项研究为评估和检测钢桥面上 EA 路面的隐蔽性损伤奠定了坚实的基础。

期刊介绍: The Journal Structural Control and Health Monitoring encompasses all theoretical and technological aspects of structural control, structural health monitoring theory and smart materials and structures. The journal focuses on aerospace, civil, infrastructure and mechanical engineering applications. Original contributions based on analytical, computational and experimental methods are solicited in three main areas: monitoring, control, and smart materials and structures, covering subjects such as system identification, health monitoring, health diagnostics, multi-functional materials, signal processing, sensor technology, passive, active and semi active control schemes and implementations, shape memory alloys, piezoelectrics and mechatronics. Also of interest are actuator design, dynamic systems, dynamic stability, artificial intelligence tools, data acquisition, wireless communications, measurements, MEMS/NEMS sensors for local damage detection, optical fibre sensors for health monitoring, remote control of monitoring systems, sensor-logger combinations for mobile applications, corrosion sensors, scour indicators and experimental techniques.
