• Abstract:
  The economic burden associated with repairing and maintaining existing highway
  
  pavements is rapidly consuming an increasingly significant portion of the annual
  
  transportation budget. One of the major areas of concern is the repair of rigid pavements
  
  resulting from premature distress at transverse contraction joints. The performance of
  
  Portland cement concrete joints in transferring traffic loads to adjacent slabs is influenced by
  
  several factors, including temperature and moisture distributions within the slabs, physical
  
  properties of the base and subgrade underlying the pavement, moisture content of the
  
  subgrade, and the type, size and spacing of dowel bars. Finite element methods have been
  
  used with some success in analyzing concrete pavement systems containing joints and
  
  cracks. The accuracy of these methods, however, depends upon how realistically the
  
  properties of the concrete and subgrade, the dowel concrete interaction, and traffic loading
  
  can be modeled. These procedures must then be verified and calibrated with data obtained
  
  on in-service pavements. To date, stresses induced in dowel bars and concrete slabs from
  
  environmental cycling and dynamic loading have not been determined in the field.
