• Abstract:
  The Illinois Department of Transportation (IDOT) currently has an existing jointed plain concrete pavement
  
  (JPCP) design based on mechanistic-empirical (M-E) principles. However, their continuously reinforced concrete
  
  pavement (CRCP) design procedure is empirical and based on a modified AASHTO nomograph for jointed
  
  reinforced concrete pavement. The objective of this study was to develop and implement an M-E design
  
  procedure that IDOT could use for routine CRCP design. The proposed procedure is based on mechanisticempirical
  
  design principles taken largely from the models presented in NCHRP 1-37A and on work completed by
  
  Dr. Dan Zollinger of Texas A&M University. The equations for calculating the mean crack spacing and the
  
  number of punchouts per mile at the end of the design life for a given traffic volume, pavement layer and CRC
  
  slab geometry, shoulder type, and layer material properties have been implemented in a user-friendly
  
  spreadsheet. Several new developments in the proposed design process are fatigue damage accumulations at
  
  the critical top and bottom location in the CRCP slab, equations for calculating the equivalent damage ratio for
  
  several shoulder types and crack stiffness values, application of a strength reduction factor to the concrete
  
  stress ratio calculated at the surface of the CRCP, and a new logistic-type punchout prediction model. Due to
  
  the numerous measured and assumed input variables in this CRCP design framework, the mechanistic analysis
  
  was calibrated against CRCP field performance data from Illinois and CRCP accelerated pavement test data
  
  completed at the University of Illinois.
