Guest Lecture by Prof. Hao Wang

Prof. Hao Wang is Professor and Graduate Program Director of Department of Civil and Environmental Engineering at Rutgers University, USA. He is currently a guest researcher at TU Dresden, Germany, under TU Dresden fellowship, contributing to the ongoing DFG funded research project SFB/TRR 339.

His research is focused on integrating innovative materials, computational modeling, non-destructive testing, and AI tools to realize sustainable, resilient, and smart pavement and transportation infrastructure. He is a Fellow of the ASCE Engineering Mechanics Institute (EMI) and the recipient of ASCE Huber Award and AASHTO High Value Research Project Award. He received his Ph.D. in civil engineering from the University of Illinois at Urbana-Champaign in 2011.

The topic of his presentation was “Multi-Scale and Multi-Physics Modeling of Asphalt Pavement”

Abstract:

This presentation will focus on the modeling and characterization of asphalt pavement across multi-scales and multi-physics, aiming to enhance its durability, sustainability, safety, and resilience. At the nanoscale, molecular dynamics simulation is utilized to understand asphalt binder diffusion, cohesion, and adhesion. At the micro-scale, multi-phase composite models are built to study the mechanical and thermal properties of asphalt concrete. At the macro-scale, analytical and numerical models are developed to simulate dynamic pavement responses, crack propagation, and tire-pavement interaction. These simulation results provide valuable insights for sustainable material design, pavement performance prediction, and the digital twin of roadway systems.
