Special Issue Information

Dear Colleagues, 

As global infrastructure ages and the demand for sustainable development intensifies, innovative sensor technologies are emerging as critical tools to ensure the safety, resilience, and environmental efficiency of built environments. This Special Issue, "Advances in Sensors for Sustainable Infrastructure: Inspection, Monitoring, and Maintenance", seeks to highlight cutting-edge research and practical applications of sensor-based solutions addressing the challenges of modern infrastructure systems. By focusing on inspection, real-time monitoring, and lifecycle maintenance, this collection aims to bridge the gap between technological innovation and sustainable new construction with existing infrastructure practices.

The topics to be covered include, but are not limited to, the following:

  • Advanced sensor methods for inspecting bridges and infrastructure;
  • Real-time monitoring of construction processes;
  • Practices for monitoring decarbonization in construction, reducing the embodied carbon in materials;
  • Machine learning for predictive maintenance and risk assessment;
  • Robotics and automation in infrastructure maintenance.

In railway infrastructure, particularly where concrete sleepers are employed, certain critical zones exhibit pronounced degradation of the ballast layer. Previous studies have identified several contributing factors, including the presence of welds, heterogeneity in the substructure beneath the sleepers, and variations in the track’s geometric parameters. Of these factors, the presence of welds seems to have the most significant influence. This article aims to determine whether differences in the ballast railway track’s response to traffic loads at weld locations can be identified in the initial phase, before obvious damage appears. Vibration responses in terms of displacement, velocity, and acceleration were measured on upgraded concrete sleepers equipped with rubber under-sleeper pads. The results indicate that velocities and accelerations at rail weld locations differ significantly from those in adjacent track sections, when the railway track is in an intact, undamaged condition. These results suggest a high likelihood of damage formation in these critical locations, indicating the necessity of preventive measures to mitigate damage. Possible mitigation measures that could help reduce the formation of damage are proposed. Full article
