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.
