Understanding Urban Infrastructure: Maintenance Challenges and Technologies

Urban infrastructure forms the backbone of our cities, yet it faces significant challenges in maintenance and renewal. This presentation by Dr. Monica A. Starnes examines the current status of urban infrastructure, including underground utilities and pavement systems. It highlights innovative inspection technologies such as ground-penetrating radar and electromagnetic locators, which help assess conditions and ensure safety. Discover the complexities of maintaining our infrastructure and the research and development efforts aimed at improving infrastructure longevity and effectiveness.
