Title: K-VALUE-DEFLECTION RELATIONSHIP FOR AC PAVEMENTS - FINAL REPORT
Abstract: AN EVALUATION OF A PRELIMINARY K-VALUE VERSUS DEFLECTION RELATIONSHIP FOR AC PAVEMENTS IS REPORTED. BY A LIMITED AMOUNT OF PLATE BEARING AND BENKELMAN BEAM DEFLECTION TESTS, THE K-VALUE VERSUS DEFLECTION RELATIONSHIP WAS FOUND TO BE VALID WITH MINOR MODIFICATION. A PROCEDURE IS PRESENTED BY WHICH PAVEMENT DEFLECTION MEASUREMENTS MAY BE UTILIZED TO PREDICT THE K-VALUE OF AN EXISTING AC ROADWAY FOR PCC OVERLAY THICKNESS DESIGN. PCC OVERLAY DESIGN THICKNESSES DETERMINED BY TRANSIENT PAVEMENT DEFLECTION MEASUREMENTS ARE COMPARED WITH ARBITRARY PCC OVERLAY THICKNESS DESIGNS. IT WAS CONCLUDED THAT THE K-VALUE OF AN EXISTING AC ROADWAY CAN BE PREDICTED FROM PAVEMENT DEFLECTION MEASUREMENTS WHICH GENERALLY RESULT IN A REDUCTION IN PCC PAVEMENT THICKNESS REQUIREMENTS. /AUTHOR/
