S. (Shi) Xu


Shi Xu is currently a PhD candidate from Material & Environment section at the faculty of Civil Engineering and Geosciences at Delft University of Technology in the Netherlands. With the support of China Scholarship Council, he started his PhD project from 2015 right after he got his master degree in Wuhan University of Technology.


His research focus is to improve the healing capacity of asphalt pavement with self-healing technologies. His calcium alginate capsules healing system has been proved to have significant healing effect in asphalt. He is specialized in asphalt design, material testing, healing effect evaluation and numerical simulation.

Self-healing Porous Asphalt: A Combination of Encapsulated Rejuvenator and Induction Heating.
Self-healing asphalt is a novel approach to prolong service life of asphalt pavement, including induction healing and microcapsule-healing. Although the feasibility of the concepts of induction-healing and microcapsule-healing asphalt concrete have been proven, there are still many key problems to be solved such as the aging problem in induction-healing and the difficult to trigger problem in microcapsule-healing. This project aims to achieve a better healing in porous asphalt concrete by combining the advantages of induction-healing and microcapsule-healing.
