Building and preserving efficient, reliable, and sustainable roads is crucial for economic and social development. The design of road materials and structures significantly influence road durability. The main components of road materials are bitumens, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, and geo-composites. The new and innovative materials, mix design, soil stabilization and environmental aspects of handling and re-use of road materials are also crucial. Road performance can be affected by vehicle loading and environmental conditions including light, temperature, oxygen, and moisture etc. An accurate assessment of road performance, stress and strain state, and the environmental effects has always been a challenge faced by this industry.

This Special Issue encourages submissions of recent work that furthers an understanding of the performance of road materials and structures. This Special Issue also lays out an interdisciplinary framework that not only aims to advance specific areas of science and engineering but also to help advance the state of practice in road engineering. Review articles that describe the current state of the art are also encouraged.

Potential topics include but are not limited to the following:

• The aging and recycling of asphalt materials
• Fatigue cracking and self-healing of pavement materials
• Innovative methods for characterization of sustainable pavement materials
• Multi-scale and multi-physics characterization of asphalt concrete and pavement
• No-destructive testing and evaluation
• Testing and evaluation of the interfacial interactions between the asphalt binder and mineral aggregate
• Vehicle-tire-pavement interaction and traffic loading
• Accelerated and full scale pavement testing
• Emerging technologies and materials for the preservation and maintenance of pavements
• Design and treatment of special soil subgrade
• Performance and test methods of subgrade
• Numerical/analytical models
