DESCRIPTION:The integral bridge typology has become the first 
 choice for road bridges in the U.K. Without any jo
 ints between the bridge deck and abutments\, maint
 enance needs are considerably lower than those for
  a conventional structure with bearings and expans
 ion joints. However\, the use of integral bridges 
 is currently restricted to moderate span lengths a
 nd skews due to concern for soil settlement and hi
 gh earth pressures developing in the backfill soil
  from thermal movements of the bridge deck. The cu
 rrent design code PD 6694-1 is considered by many 
 to be overly conservative and is thought to mischa
 racterise the soil-structure interaction behaviour
  at play. In this talk\, the experimental and fiel
 d work carried out at Cambridge and the University
  of Pretoria will be presented\, giving insight in
 to where current design could be improved.
