Sustainable and durable pavement infrastructure is critical for current economic and environmental challenges. New theories, new methods, new technologies and new materials related to pavement engineering are emerging. Adhesion between aggregates is undoubtedly one of the major challenges in all sectors where pavements are used. This affects the durability, service quality and environmental friendliness of the pavement. The pavement community has taken important steps to make progress in this direction by modifying their virgin materials, such as modified bitumen or modified cement slurry, and using polyurethane and bio-materials as substitutes for raw pavement aggregate adhesives. Recent research has shown that innovations in pavement adhesion technology have the potential to achieve similar or even better performance compared to their conventional counterparts, while reduce greenhouse gas (GHG) emissions, energy demands, and costs in pavement life cycle. However, the validity of such claims is not indisputable, a they are contingent upon follow-up surveys and simulation predictions.
This special issue (SI) will bring together recent progress and challenges related to adhesion of pavement materials, aiming to contribute to achieving sustainable and durable pavement, including reuse of waste and secondary adhesives, modified pavement materials, low-carbon pavement materials, future pavement adhesives recyclability, and advancements in surveys+analysis and simulation predictions assessment methodologies.
This SI welcomes submissions in the forms of original research, comprehensive review, analysis, or simulation studies on, but not limited to, the following topics:
- Low-carbon construction adhesives for pavements
- Modified construction adhesives for pavements
- Use of bio-wastes and construction or industrial wastes adhesives in pavements
- rejuvenating technology and future rejuvenation of pavements adhesives
- Consideration of leaching in environmental and toxicological impact assessment
- Aggregate adhesion modeling simulation
