Special Issue Information

Dear Colleagues,

Traditional asphalt pavements face significant challenges in durability and performance under demanding conditions (heavy traffic, extreme climates, aging). The increasing demand for sustainable infrastructure necessitates innovative solutions. Function-oriented modification of asphalt binders and mixtures offers a promising pathway to enhance performance, extend service life, and reduce environmental impact. This Special Issue focuses on research advancing asphalt materials through targeted functional enhancements. Key areas include the following:

l Function-Oriented Materials: Novel modifiers (polymers, nanomaterials, bio-based, recycled) designed for specific performance improvements (e.g., high-temperature stability, low-temperature cracking resistance, fatigue endurance).

l Mixture Design and Meso-Structure: Optimized mixture design methodologies and characterization of meso-structural features (aggregate skeleton, air void distribution, binder film) influencing performance.

l Surface Functionality: Development and evaluation of surfaces with enhanced properties (e.g., skid resistance, noise reduction, permeability, self-healing potential, thermal properties).

l Performance and Sustainability: Comprehensive evaluation of mechanical properties, durability, long-term performance, and contributions to sustainability (resource efficiency, recyclability, reduced carbon footprint).

We welcome original research and reviews addressing the design, characterization, and application of function-oriented modified asphalt and mixtures for next-generation, high-performance, and sustainable pavements.

Reducing the environmental impacts associated with road infrastructure is a key challenge in the transition toward more sustainable construction practices. Asphalt pavements, due to their extensive material use and energy demand over long service periods, offer significant opportunities for improvement through innovative materials and production technologies. This study evaluates the environmental performance of an asphalt pavement incorporating recycled tire crumb rubber and a warm mix asphalt additive (CR + WMA) in comparison with a conventional hot mix asphalt (HMA) pavement. A comprehensive cradle-to-grave life cycle assessment (LCA) was conducted in accordance with ISO 14040/44 standards, encompassing material production, construction, maintenance, and end-of-life stages. Different pavement service life scenarios were considered, and environmental impacts were quantified using sixteen midpoint categories of the environmental footprint (EF) 2.0 method. To enable a consistent comparison between pavement alternatives with different durability, results were normalized using a functional unit of 1 m2·year. The results show that the CR + WMA pavement consistently exhibits lower environmental impacts than the conventional HMA pavement across all impact categories. When identical service lives are assumed, impact reductions are primarily associated with lower production temperatures, partial substitution of virgin bitumen with recycled crumb rubber, reduced maintenance needs, and the normalization of life cycle impacts when results are expressed per m2·year. Overall, the CR + WMA pavement reduces life cycle environmental impacts by approximately 45%–60% across all EF midpoint categories compared to the conventional HMA pavement, depending on the impact category and service life scenario considered. These findings demonstrate the importance of explicitly accounting for service life and maintenance in pavement LCAs and highlight the potential of CR + WMA technology to reduce the life cycle environmental footprint of asphalt pavements, supporting more informed infrastructure design decisions and the development of more sustainable road pavement solutions.
