Special Issue Information

Dear Colleagues,

Transitioning to sustainable and resilient infrastructure is a critical global priority. Infrastructure systems and networks are pressured by climate change, aging assets, increasing service demand and environmental regulations. Therefore, it is important to identify innovative solutions that reduce environmental impacts while enhancing infrastructure durability and performance.

This Special Issue focuses on the latest advancements in infrastructure technology, materials and management strategies that improve the sustainability, durability and resilience of infrastructure. We welcome and invite the submission of original research and review articles that address the following topics: (i) Innovative materials and composites for infrastructure applications; (ii) structural design, rehabilitation, and maintenance strategies; (iii) life-cycle assessment, carbon footprint, and sustainability evaluation; (iv) resilience modeling, risk assessment, and adaptation to climate and operational challenges; and (v) digital tools for infrastructure management, monitoring, and decision support.

The aim is to share knowledge on how next-generation solutions can meet the technical demands of modern infrastructure while aligning with environmental and socio-economic goals. We encourage interdisciplinary submissions that bridge materials science, structural and civil engineering, asset management and sustainability assessment, while demonstrating practical relevance, scalability and implementation potential in real-world cases.

The development of recycled asphalt mixtures combining reduced production temperatures with adequate mechanical performance remains challenging in circular pavement engineering. This study assessed the performance-based redesign of a half-warm mix asphalt (HWMA) produced at approximately 90 °C with a very high reclaimed asphalt pavement (RAP) content and foamed bitumen, using previously validated cold recycled mixture (CRM) and hot recycled mix asphalt (HRMA) formulations as contextual benchmarks. An initial CRM-derived HWMA was evaluated to assess whether cold-recycling design logic could be transferred to half-warm production without added water or cement. Although the mixture showed satisfactory volumetric and moisture-related responses, wheel tracking identified rutting as the governing limitation. The mixture was redesigned by incorporating coarse steel slag aggregate (SSA) to correct the aggregate size distribution, reducing filler content and adjusting the added foamed bitumen while maintaining RAP and SSA at 98% of the aggregate skeleton. The combined redesign reduced the wheel-tracking slope in air from 1.25 to 0.32 mm/103 cycles and the proportional rut depth in air from 28.1% to 10.4%. Nevertheless, the redesigned HWMA remained less rut-resistant than both benchmarks, confirming the need for further optimisation. It achieved stiffness close to the HRMA benchmark and a fatigue response compatible with base-layer application, although moisture durability requires further validation. Overall, the study demonstrates the feasibility of a sequential performance-based redesign approach for high-RAP HWMA while highlighting the need for systematic optimisation and field validation before broader implementation.

This paper develops a shock-absorbing asphalt mixture for pedestrian pavements that mitigates the impact of normal walking on pedestrians’ bodies by incorporating crumb rubber from recycled tires to produce a soft mixture. This aims to reduce injuries to vulnerable road users, enable the rethinking of urban pavement designs, and address the major challenges facing societies, ultimately achieving more sustainable, resilient, and safer cities. To promote land sustainability, the designed asphalt mixture should be pervious, allowing water to infiltrate into the underlying soil. The development of the asphalt mixture followed an experimental methodology that involved formulating asphalt mixtures with conventional bitumen, polymer-modified bitumen, and bituminous emulsion. The shock-absorbing capability was evaluated by measuring the deformation of the asphalt mixture over time in response to a falling weight from a Light Falling Weight Deflectometer. Permeability capabilities were assessed through the permeability test. Subsequently, the asphalt mixture was characterized according to its macrotexture, friction, air void content, rutting resistance, and stiffness to assess its suitability as a walking surface material. Results indicate that increasing rubber content enhances deformation capacity and improves cushioning but reduces stiffness. Among the solutions, mixtures with polymer-modified bitumen and intermediate rubber content achieved the balance between impact attenuation and mechanical performance. Full article
