A STUDY OF SLAB ACTION IN CONCRETE PAVEMENTS UNDER STATIC LOADS

INVESTIGATIONS WERE MADE OF A FULL-SIZE LABORATORY-CAST CONCRETE HIGHWAY SLAB TO DETERMINE WHETHER, AS PREVIOUS STUDIES CONCLUDED, TWO AND THREE AXLES COULD BE SPACED SO THAT FOR A GIVEN LOAD THE STRAINS INDUCED BY THE TWO OR THREE AXLE SYSTEM WERE LESS THAN THOSE CAUSED BY ONE AXLE. FOR A SUBGRADE MODULUS OF 60 LB/CU IN., THE STRAINS CAUSED BY A SINGLE AXLE UNDER 18,000 POUNDS LOAD WERE GREATER THAN THOSE CAUSED BY ANY TWO OR THREE AXLE SYSTEM TESTED AT THE SAME LOAD PER AXLE. AT A SUBGRADE MODULUS OF 110 LBS/CU IN. TWO AXLES CLOSELY SPACED AT THE CORNER PRODUCED STRAINS SLIGHTLY LARGER THAN THOSE FOUND UNDER OTHER ARRANGEMENTS, BUT AT AXLE SPACING OVER FIVE FEET, THE SINGLE AXLE LOAD PROVED TO BE MOST SEVERE. /AUTHOR/
