A LABORATORY STUDY OF THE RELATION OF STRESS TO STRAIN FOR A CRUSHED LIMESTONE BASE MATERIAL

A NEWLY DEVELOPED OPTICAL TRACKER MEASURING SYSTEM WAS USED FOR OBSERVING THE DYNAMIC DISPLACEMENT VECTOR AT POINTS ON THE PERIPHERY OF A COMPACTED TRIAXIAL TEST SPECIMEN OF GRANULAR MATERIAL SUBJECTED TO RAPID, REPETITIVE LOADING. THE MATERIAL WAS A CRUSHED LIMESTONE OF THE TYPE USED IN HIGHWAY PAVEMENTS. THE DISPLACEMENT DATA WERE CONVERTED TO COMPONENTS OF NORMAL STRAIN, AND A MATHEMATICAL MODEL WAS DEVELOPED THAT EXPRESSED EACH STRAIN COMPONENT AS A FUNCTION OF THE APPLIED STRESSES. THE MODEL CONTAINED A VARIABLE MODULUS DEPENDENT UPON BOTH THE LATERAL PRESSURE APPLIED TO THE SPECIMEN AND ITS STRESS HISTORY /AUTHOR/
