Special Issue Information

Dear Colleagues,

High-performance and functional pavement and trackbed materials are recognized as integral components of the built environment, playing a critical role in the sustainability, resilience, and intelligent operation of modern cities and infrastructure systems. Beyond their conventional structural functions, next-generation pavements are being engineered as multifunctional building materials capable of self-healing, thermal regulation, deicing and snow-melting, noise and vibration mitigation, and in situ sensing of loading and environmental conditions.

Recent advances in thermally functional and energy-harvesting pavements, semi-flexible and grouted systems, as well as epoxy- and resin-modified materials, have significantly enhanced durability, service life, and climate adaptability, while contributing to low-carbon and resource-efficient built environments. These materials enable new opportunities to integrate pavement and trackbed systems into broader frameworks of building and urban infrastructure performance.

This Special Issue, “High-Performance and Functional Pavement and Trackbed Materials for Sustainable Built Environments”, aims to collect high-quality research on the design, characterization, modeling, and implementation of advanced pavement and trackbed materials that combine superior mechanical performance with multifunctionality, environmental sustainability, and climate resilience. Contributions addressing material behavior, system-level performance, life-cycle assessment, and practical applications within the built environment are particularly encouraged.

Key topics include, but are not limited to, the following:

  • Self-healing asphalt and rejuvenator-based pavement materials;
  • Electrically or thermally functional pavements for heating, deicing, and snow-melting;
  • Thermal regulation and energy-harvesting technologies in pavement and trackbed systems;
  • Semi-flexible and grouted pavement materials as composite building materials;
  • Epoxy- and resin-modified pavements and trackbeds;
  • Self-sensing, piezoresistive, and multifunctional pavement materials;
  • Climate-resilient and durable pavement design within the built environment;
  • Life-cycle performance, sustainability, and carbon assessment of functional pavements.

Phosphogypsum, the primary solid waste from the wet-process phosphoric acid industry, poses significant environmental and health risks due to large-scale stockpiling. To promote its resource utilisation, this study systematically evaluated the solidification and stabilisation performance of phosphogypsum–coal fly ash cementitious material (PAC) for Cr(VI)-contaminated soil under high-chloride conditions. Phosphogypsum reactivity was enhanced via mechanical activation and high-temperature calcination. An orthogonal experimental design was employed to analyse the effects of multiple factors—including calcination temperature and duration—on compressive strength and heavy metal leaching behaviour. Results show that PAC prepared from coal ash calcined at 600 °C for 3 h exhibits excellent mechanical properties and Cr(VI) stabilisation efficacy under high-chloride conditions, achieving a maximum compressive strength of 28.75 MPa and a Cr(VI) leaching concentration as low as 15.69 μg/L. Microstructural characterisation revealed the synergistic formation of a dense framework between C–S–H gel and calcium aluminate, conferring superior mechanical strength. Substitution and chelation mechanisms of Cl ions played a key role in enhancing corrosion resistance. This study provides theoretical support and technical guidance for the high-value utilisation of phosphogypsum-based materials in remediating saline–alkali-contaminated soils. Full article

Aeolian sand is abundant in arid deserts, but its high replacement in cement-stabilized bases can reduce strength and raise cracking risk. Strain localization and crack evolution are also poorly quantified. This study aimed to optimize the early age performance of cement-fly ash stabilized aeolian sand gravel (CFSAG) and clarify its failure mechanism. A Box–Behnken response surface methodology varied the cement content, cement-to-fly ash ratio, coarse aggregate gradation, and aeolian sand content. The 7-d unconfined compressive strength (UCS) and splitting tensile strength (STS) were tested. Digital image correlation (DIC) recorded full-field strains and crack metrics in compression and splitting. SEM–EDS was used to interpret microstructural changes. The aeolian sand content dominated UCS, whereas the cement content and cement-to-fly ash ratio mainly controlled STS. Factor interactions were non-negligible and supported the joint optimization of the two strength indices. DIC identified a crack propagation threshold near 0.9 Pmax in splitting. Excess aeolian sand (>50%) caused earlier localization, more cracks, and wider openings. In the appropriate amount of aeolian sand mixtures, hydration products filled voids and improved paste continuity. SEM–EDS indicated that excessive fines increased porosity and weakened the interfacial transition zone. Overall, the combined RSM–DIC–SEM approach links mix design with deformation and microstructure evidence. It provides practical guidance to balance strength and cracking resistance at early ages for cement-stabilized bases in desert highway engineering. Full article
