Al-Khalid, Hussain - University of Liverpool

个人简介

Dr Khalid has developed a dynamic research group in Pavement Engineering at Liverpool University, with funding from the public sector and private organisations, populated by a group of vibrant research students and assistants engaged in various research projects within the field. One of the main focus points of the group is sustainability, with current and recent projects on the use of waste, by-product and secondary materials in the transport infrastructure, together with adopting environmentally conscious techniques in pavement construction and maintenance. Dr Khalid's background and interests centre primarily on experimental and analytical investigation of fundamental material behaviour of asphalt pavements and granular materials. His research focuses on binder/mastic rheology, understanding and better prediction of fatigue cracking in asphalt pavements using state-of-the-art techniques, such as the Viscoelastic Continuum Damage (VECD) and Elasto-Plastic Fracture Mechanics (EPFM) Theories, and development of tools to improve understanding of crack propagation characteristics of asphalt pavements. His other research interests include pavement surface characteristics, such as slip resistance of modular pavements.

One of the remits of the ILC Chairmanship was the coordination of the Mentoring Scheme for the MEng Programme students, which provided vital interaction between civil engineering practitioners and UG students. At present, I look after Assessment and Approvals for Civil Engineering, dealing with organising CA elements and summative assessment for the programme, together with approvals for new modules and programmes on behalf of the School of Engineering.
