Personal profile

Research profile

Dr. Yi Li is an Assistant Professor at the Pavement Engineering Section, part of the Engineering Structures Department in Civil Engineering and Geosciences at Delft University of Technology. Specializing in the circular economy of road infrastructure,Yi is dedicated to enhancing sustainability and resource efficiency in pavement design and maintenance.

Central to Yi's research is the development of innovative approaches to circular road material labeling and waste management, parallel to exploring the sustainable reuse and recycling of road materials. This dual approach underscores the importance of not only identifying and categorizing materials for their potential lifecycle extension but also ensuring their integration back into the infrastructure in an environmentally friendly manner.

Yi's research also extends to investigating the dynamics between road maintenance monitoring, technology labeling, and the impact of extreme climate conditions on maintenance strategy, Yi aims to forge climate-performance relationships that inform more resilient infrastructure development.

By leading the above multidisciplinary research, Yi aims to employ a comprehensive strategy that integrates advanced analytical tools, multivariate statistics, and multi-cycle-oriented multicriteria decision-making systems. This approach not only addresses the challenges posed by climate change and resource depletion but also pioneers new standards for sustainable road engineering.

In addition to her academic pursuits, Yi aims to actively contribute to the broader scientific and engineering community, aiming to foster collaboration and innovation in the field of sustainable road infrastructure. Her work will not only address the technical and environmental challenges associated with modern road engineering but also set a precedent for future research and practices in sustainable infrastructure development.
