  for   rigid   pavement   joints   that   can   be   implemented   into   advanced   pavement   design   models.   his   report   documents   a   background   investigation   including   a   comprehensive   review   of   rigid   pavement   joint   models   ith   articular   mphasis   n   heir   joint   nd   oundation   modeling   apabilities.   The   major   istorical   developments   in   airport   rigid   pavement   design   are   discussed.   losed-form   solutions   akin   to   those   by   Westergaard   were   derived   in   this   study   for   the   maximum   responses   on   the   unloaded   side   of   a   rigid   pavement   slab   edge   capable   of   a   degree   of   load   transfer.   When   used   together   with   Westergaard's   own   closed-form   equations   for   the   free-edge   problem,   the   formulae   derived   in   this   study   constitute   a   complete   solution   of   the   edge   load   transfer   problem,   ecognized   over   the   years   as   a   critical   onsideration   in   rigid   pavement   design.   he   newly   derived   solution   is   presented   in   convenient   form   for   routine   engineering   application   and   is   compared   to   earlier   finite   element   data.   he   improvement   in   ease   of   application   and   precision   is   considerable.   17.   Keywords   Analysis   Response   models   Design
