NON-DIMENSIONAL TECHNIQUES APPLIED TO RIGID PLATE BEARING TESTS ON FLEXIBLE PAVEMENTS

NON-DIMENSIONAL TECHNIQUES BASED ON THE METHODS OF DIMENSIONAL ANALYSIS PROVIDE A RATIONAL BASIS FOR ANALYZING RIGID PLATE BEARING TESTS ON FLEXIBLE PAVEMENTS. TEST DATA HAVE BEEN SUCCESSFULLY ANALYZED BY SUCH TECHNIQUES. THE SURFACE DEFLECTION IS EXPLICITLY EXPRESSED AS A FUNCTION OF THE APPLIED LOAD, BEARING PLATE DIAMETER, PAVEMENT THICKNESS, AND THE STRENGTH CHARACTERISTICS OF THE SUBGRADE. SEVERAL ILLUSTRATIVE EXAMPLES ARE PRESENTED USING THE DERIVED DEFLECTION EQUATION TO INDICATE POSSIBLE APPLICATIONS. FOR THE HYBLA VALLEY DATA ANALYZED, THE ANALYSIS SHOWS THAT THE LOAD-CARRYING CAPACITY OF THE FLEXIBLE PAVEMENT AS EXPRESSED BY THE SURFACE DEFLECTION IS DEPENDENT ON THE TOTAL PAVEMENT THICKNESS AND NOT ON ITS PROPORTION OF ASPHALTIC CONCRETE OR BASE COURSE. /AUTHOR/
