PhD Student,
Mr Hanyu Zhang is currently a PhD student at Nottingham Transportation Engineering Centre (NTEC), University of Nottingham. Hanyu was awarded BSc (2017) and MSc (2020) degrees from Southeast University in Nanjing, China. His PhD project is fully funded by the University of Nottingham, Nynas, and Colas. Hanyu's research mainly focuses on the multiscale and multiphysics modelling of asphalt pavements and predicting their long-term performance using FEM.

Oxidative ageing of asphalt pavements is a multiphysics problem. Ignoring the circularly dependent of multiphysics in oxidative ageing is the main research gap in the pavement field ageing modelling. The current mechanical analyses of asphalt pavements via FEM lack the consideration of road material deterioration due to ageing, leading to an inaccurate performance prediction of asphalt pavements. Besides, the traditional time domain-based computational approach for analysing the mechanical responses of asphalt pavements is time-consuming and impossible to predict the long-term performance of asphalt pavements. In this project, a coupled multiphysics field ageing and viscoelastic-damage model of asphalt pavements will be firstly established. After that, a developed multiscale computational method will be employed to solve the high cycle fatigue problems in pavement structures with an acceptable computation efficiency. This project would contribute to the accurate long-term performance prediction of asphalt pavements.
