AN EXTENSION OF RIGID PAVEMENT DESIGN METHODS

THIS PAPER VERIFIES AND EXTENDS CERTAIN DEVELOPMENTS IN THE AASHO INTERIM PAVEMENT DESIGN GUIDE. A CHOICE OF MATHEMATICAL MODELS IS MADE BASED ON STUDIES OF THE AASHO AND MARYLAND ROAD TESTS STRESS DATA, AS WELL AS DATA FROM IN -SERVICE PAVEMENTS. MATHEMATICAL DERIVATIONS AND ASSUMPTIONS ARE PRESENTED IN AN APPENDIX TO PROVIDE A BASIS FOR FUTURE WORK ON THIS SUBJECT. AS AN EXTENSION OF THE INITIAL WORK, THE DESIGN THICKNESS EQUATION IS EXPANDED TO INCLUDE THE CONCRETE MODULUS OF ELASTICITY, TOTAL TRAFFIC, AND PAVEMENT CONTINUITY /JOINTED OR CONTINUOUS/. A NOMOGRAPH IS PRESENTED THAT ALLOWS A QUICK SOLUTION TO THE EXPANDED EQUATION. NEW DESIGN CHARTS ARE PRESENTED FOR DESIGN OF THE REINFORCING STEEL IN JOINTED AND CONTINUOUSLY-REINFORCED PAVEMENTS. IN ADDITION, A NOMOGRAPH FOR SOLVING BAR SPACING AND BAR SIZE IS INCLUDED. /AUTHOR/
