ENGINEERS HAVE ALWAYS ASSUMED THAT SOILS DERIVED FROM THE SAME PARENT MATERIAL AND UNDER THE SAME ENVIRONMENTAL CONDITIONS WOULD HAVE SIMILAR ENGINEERING PROPERTIES. TO ASCERTAIN THE EXTENT TO WHICH THIS IS TRUE A STUDY WAS CONDUCTED ON TWO SOILS OBTAINED FROM MADISON AND TIPTON COUNTIES, IND., AND PEDOLOGICALLY CLASSIFIED AS BROOKSTON AND CROSBY. TWENTY BORINGS WERE OBTAINED FROM EACH COUNTY--10 FROM BROOKSTON SOILS AND 10 FROM CROSBY SOILS. SAMPLES OF THESE SOILS WERE SUBJECTED TO THE FOLLOWING TESTS AND THE RESULTS ANALYZED STATISTICALLY: ATTERBERG LIMITS, STANDARD AASHO COMPACTION, HVEEM STABILOMETER AND SWELLING PRESSURE, CALIFORNIA BEARING RATION, GRAIN-SIZE DISTRIBUTION, AND UNCONFINED COMPRESSION. X-RAY DIFFRACTION TESTS WERE CONDUCTED ON 8 SAMPLES--4 FROM THE RISES AND 4 FROM THE DEPRESSIONS. FROM THE STATISTICAL ANALYSIS, UTILIZING ANALYSIS OF VARIANCE TECHNIQUES, IT WAS FOUND THAT SOIL VARIABILITY IS A FUNCTION OF THE PROPERTY BEING MEASURED. THE VARIABILITY OF THE SOILS, AS DEFINED BY THE PARAMETERS OF THESE TESTS, WAS LARGE. THE CONSEQUENCES OF SUCH VARIATION AS IT PERTAINS TO PAVEMENT DESIGN WERE CONSIDERED. DIAGRAMS ARE PRESENTED WHICH RELATE NUMBER OF BORINGS REQUIRED TO PREDICT THE MEAN VALUE OF A GIVEN TEST PARAMETER TO A DESIRED DEGREE OF PRECISION. /HRB/
