Title: VERTICAL STRESSES IN SUBGRADES BENEATH STATICALLY LOADED FLEXIBLE PAVEMENTS
Accession Number: 00234399
Record Type: Component
Abstract: FULL-SCALE STATIC LOAD TESTS HAVE BEEN MADE OF SINGLE DUAL, AND DUAL TANDEM TRUCK TIRE LOADS ON FLEXIBLE PAVEMENTS TO DETERMINE THE STRESS DISTRIBUTION IN THE SUBGRADE AND THE RELATIVE LOAD SPREADING ABILITY OF DIFFERENT BASE COURSE MATERIALS NOW IN USE BY THE GEORGIA HIGHWAY DEPARTMENT. THE MEASURED STRESSES BELOW TOPSOIL AND SOIL BOUND MACADAM BASE PAVEMENTS ARE COMPARABLE TO THOSE COMPUTED BY THE BOUSSINESQ THEORY. THE MEASURED STRESSES BELOW THE SAND ASPHALT ARE COMPARABLE TO OR SLIGHTLY MORE THAN THOSE COMPUTED BY THE BOUSSINESQ. THE STRESSES FOUND BELOW THE SOIL CEMENT BASE ARE MUCH LOWER THAN THOSE GIVEN BY BOUSSINESQ AND ARE COMPARABLE TO THE STRESSES FOUND BY THE TWO LAYER ELASTIC THEORIES. ASPHALTIC CONCRETE OVERLAYS REDUCE THE STRESSES TO THE SAME DEGREE AS AN EQUAL THICKNESS OF THE TOPSOIL OR SOIL BOUND MACADAM. /AUTHOR/
