EU Horizon 2020-Marie Skłodowska-Curie Actions (MSCA) Individual Fellowships (IF) project: Fatigue Damage and Healing of Bituminous Materials: from Microscopic Mechanism towards Lifetime Extension (FHBMicro)

Fellow: Dr. Yangming Gao

Host: Delft University of Technology (TUDelft), The Netherlands

The aim of this FHBMicro project is to investigate the microscopic mechanisms of fatigue damage and healing of bituminous materials (BMs) to fundamentally extend the materials’ service life. To achieve the overall research goal, specific objectives include: (1) to investigate microscopic mechanisms of the BMs’ fatigue damage and healing, (2) to model microscopic behaviours of fatigue damage and healing and trans-scale performance prediction of the BMs, and (3) to develop and evaluate the anti-fatigue and self-healing BMs and technologies. This study will enhance the EU scientific excellence and industry leadership in the innovation, evaluation and engineering application of the durable and sustainable road materials.
