AN ANALYSIS OF WHEEL LOAD LIMITS AS RELATED TO DESIGN

A METHOD FOR CONTROLLING LOAD LIMITS AND FOR DESIGN OF BASES, USING A CONE BEARING TEST AND THE BOUSSINESQ METHOD OF LOAD DISTRIBUTION, IS PRESENTED. BASED ON CONE BEARING TESTS ON PAVEMENT SUBGRADES, A CURVE WAS DEVELOPED THAT SHOWS FOR ANY GIVEN BEARING THE THICKNESS OF THE BASE AND MAT REQUIRED BY PRESENT TRAFFIC LOADS. WHEN PLOTTED ON LOG PAPER, THE CURVE BECOMES A STRAIGHT LINE, THE EQUATION OF WHICH OFFERS A MEANS OF EXTRAPOLATING FOR THICKNESSES REQUIRED BY HEAVIER LOADS THAN THOSE IN THE CURRENT HIGHWAY RANGE. THESE DETERMINATIONS AID THE PAVEMENT DESIGN, IN ESTABLISHMENT OF LEGAL LOAD LIMITS, AND IN SETTING LOAD LIMITS DURING SEASONAL LOSSES IN STABILITY. THE EFFECT OF SINGLE AND DUAL TIRES ON LOAD BEARING CAPACITY AND THE LIMITATIONS OF ROAD RESTRICTIONS PER INCH OF TIRE WIDTH ARE DISCUSSED. MAXIMUM LOAD LIMITS PER WHEEL ARE RECOMMENDED. /AUTHOR/
