DATA ARE PRESENTED COMPARING THE DEFORMATION CHARACTERISTICS IN REPEATED LOAD TESTS OF SPECIMENS OF TWO SOILS HAVING SIMILAR STRESS-STRAIN RELATIONSHIPS IN NORMAL COMPRESSION TESTS. THE TESTS WERE PERFORMED ON A SILTY CLAY FROM VICKSBURG, MISSISSIPPI, AND A CLAYEY SILT FROM THE SUBGRADE OF THE IDAHO TEST ROAD. SPECIMENS WERE PREPARED TO A DEGREE OF SATURATION OF ABOUT 90 PERCENT BY THE METHOD USED BY THE CALIFORNIA DIVISION OF HIGHWAYS. COMPARABLE SAMPLES WERE THEN TESTED IN NORMAL TRIAXIAL COMPRESSION TESTS AND IN TRIAXIAL COMPRESSION TESTS IN WHICH THE AXIAL LOAD WAS REPEATEDLY REMOVED AND RE-APPLIED 1,000 TIMES. BY INTERPOLATION THE BEHAVIOR IN REPEATED LOAD TESTS OF SAMPLES OF THE TWO SOILS HAVING SIMILAR STRESS-STRAIN CHARACTERISTICS IN THE NORMAL COMPRESSION TESTS WAS DETERMINED AND SHOWN TO BE QUITE DIFFERENT, BOTH INSOFAR AS IRRECOVERABLE DEFORMATION AND RESILIENT DEFORMATION ARE CONCERNED. /AUTHOR/
