Materials and Infrastructure
This area has been established to conduct research, education and service activities in the field of infrastructures and related materials. It is devoted to promote sustainable practices in infrastructure engineering, enhance understanding of distress mechanisms and failure modes, develop testing and conditioning procedures to improve material characterization, and develop design approaches for pavement systems and foundations that optimize performance.
- Characterization of soil deposits, soil properties and soil variability
- Advanced sensing technologies
- Assessment and monitoring of geosystems and pavements
- Testing and characterization of asphalt binders and mixtures
- Understanding of distress mechanisms and failure modes
- Development of performance-based specifications for characterization and design
- Tire-pavement interaction
- Material recycling and reuse technologies
- Nano-modification and polymer modification of materials
- Computer/numerical modeling of material behavior
The UFTI facilities are available for advanced performance testing of infrastructure materials under a variety of conditions.
