DESCRIPTION:The integral bridge typology has become the first choice for r
 oad bridges in the U.K. Without any joints between the bridge deck and abu
 tments\, maintenance needs are considerably lower than those for a convent
 ional structure with bearings and expansion joints. However\, the use of i
 ntegral bridges is currently restricted to moderate span lengths and skews
  due to concern for soil settlement and high earth pressures developing in
  the backfill soil from thermal movements of the bridge deck. The current 
 design code PD 6694-1 is considered by many to be overly conservative and 
 is thought to mischaracterise the soil-structure interaction behaviour at 
 play. In this talk\, the experimental and field work carried out at Cambri
 dge and the University of Pretoria will be presented\, giving insight into
  where current design could be improved.
