THE ELASTIC BEHAVIOR OF SOIL-CEMENT WAS STUDIED AS A FUNCTION OF CEMENT AND CLAY CONTENT. SOIL-CEMENT IS CONSIDERED AS QUASI-ISOTROPIC AND HOMOGENEOUS. SYNTHETIC SOILS WERE EMPLOYED FOR THE MANUFACTURING OF THE TEST SPECIMENS. FOUR DIFFERENT SOIL TYPES WERE PREPARED WHICH WERE MIXED, AT THEIR OPTIMUM MOISTURE CONTENTS, WITH THREE DIFFERENT PROPORTIONS OF PORTLAND CEMENT. ALL SPECIMENS WERE CURED IN THE SAME MANNER AND FOR THE SAME PERIOD OF TIME BEOFRE THEY WERE TESTED. A 500-TON HYDRAULIC TESTING MACHINE WAS USED FOR STRESS-STRAIN MEASUREMENTS. IT WAS ESTABLISHED THAT SOIL-CEMENT IS BASICALLY SIMILAR TO PORTLAND CEMENT CONCRETE WITH RESPECT TO STRESS-STRAIN RELATIONSHIPS. THE FOLLOWING CONCLUSIONS WERE REACHED FROM THE TEST RESULTS: (1) DETERMINANT FOR THE ELASTIC BEHAVIOR OF SOIL-CEMENT IS ITS COMPRESSIVE STRENGTH, (2) THIS CAN BE INFLUENCED BY DENSIFICATION, CEMENT CONTENT, WATER CONTENT AND CLAY CONTENT, (3) UP TO ONE-THIRD OF THE COMPRESSIVE STRENGTH, ONE CAN ASSUME A LINEAR STRESS-STRAIN DIAGRAM FOR SOIL- CEMENT, (4) DEPENDABLE VALUES FOR MODULI OF ELASTICITY AND SUFFICIENTLY ACCURATE POISSON NUMBERS ARE AVAILABLE FOR THE RANGE OF PRACTICAL APPLICATION, AND (5) THEY ARE FUNCTIONS OF THE STRESS AND DEPEND STRONGLY UPON THE CEMENT CONTENT AND ON THE CLAY CONTENT. IT APPEARS POSSIBLE TO JUDGE THE ELASTIC BEHAVIOR OF SOIL-CEMENT AS A FUNCTION OF THE CEMENT AND CLAY CONTENTS AND TO OBTAIN DEPENDABLE VALUES FOR THE DIMENSIONAL DESIGN OF PAVEMENT SECTIONS.
