Recycling infrastructure materials from demolition and reconstruction for the preparation of new infrastructure materials can reduce environmental damage and carbon footprint, while enabling energy savings and maintaining social value.

There is a growing interest in new theories, methods and techniques to solve the application of recycled materials in infrastructure engineering, especially considering the significant amount of complex problems involving recycled materials in civil infrastructure. New theories, methods and techniques for key infrastructure materials using recycled asphalt pavement, recycled concrete aggregate, fly ash, foundry sand, glass cullets, crumb rubber, and recycled plastic are essential to improve the durability and life of infrastructure engineering structure.

This Special Issue brings together original research and review articles that focus on new theories, methods and techniques in reusing and recycling infrastructure materials in a variety of infrastructure engineering such as pavements, tunnels, roads, bridges, buildings, and so on. We encourage papers that explore new research perspectives and applications to experiment and numerical simulation topics.

Potential topics include but are not limited to the following:

• Empirical or theoretical model for predicting the performance of recycled infrastructure materials
• New applications of recycled infrastructure materials
• Methods of recycling of infrastructure materials
• Laboratory test methods corresponding to recycled infrastructure materials
• Long-term behavior of recycled infrastructure materials
• Reliability of recycled infrastructure structures
• Performance of recycled infrastructure materials in very aggressive environments
