Abstract :
  The analysis and design of road pavements under moving surface 
loads is an important but complex problem. Over the last three 
decades, there has been a positive evolution in philosophy and 
practice from a wholly empirical approach to pavement design, 
supported by method and recipe specifications, towards the use of a 
theoretical framework for design.
This presentation summarises recent advances in two key areas of 
pavement soil mechanics that can be readily used to develop an 
elastic-plastic theoretical framework for pavement design. The first 
area is concerned with the development and use of elastic-plastic 
shakedown theory to predict the behaviour of multilayer pavements 
under moving surface loads. A new shakedown-based analytical 
framework is then suggested for pavement design which can take into 
account both elastic and strength properties of the materials. The 
second area is on the development of more advanced soil behaviour 
models to account for the significant effect of principal stress 
rotation experienced by soils under moving traffic loads.

Speaker's Biography :
  Hai-Sui Yu is Professor of Geotechnical Engineering and Pro-Vice 
Chancellor at the University of Nottingham. In July 2011, Prof. Yu 
was admitted as Fellow of the Royal Academy of Engineering for his 
outstanding achievements in the field of geomechanics and geoengineering.
He has been a core member of TC3 of ISSMGE on Geotechnics of 
Pavements since 2002. Prof. Yu chaired the 1st International 
Conference on Transportation Geotechnics in August 2008. He has 
written two books on 
'Cavity Expansion Methods in Geomechanics' 
(2000) and 
'Plasticity and Geotechnics' (2006) and co-edited two 
further volumes on 
'Modern Trends in Geomechanics' (2006) and 
'Advances in Transportation Geotechnics' (2008).
