Abstract:
A SERIES OF COMPACTION AND STRENGTH TESTS WERE PERFORMED ON FOUR SOIL-AGGREGATE MIXTURES TO DETERMINE THEIR COMPACTION AND WET STRENGTH CHARACTERISTICS UNDER VARYING SOIL CONTENTS. ON THE BASIS OF THE TEST DATA, IT WAS INDICATED THAT, FOR A GIVEN GRADATION OF AN AGGREGATE, THERE IS AN OPTIMUM SOIL CONTENT AT WHICH MAXIMUM DENSITIES ARE ATTAINED. THE OPTIMUM SOIL CONTENT WHERE STRENGTHS ARE CONCERNED IS SOMEWHAT LESS THAN THAT INDICATED BY THE COMPACTION TESTS. MAXIMUM DENSITIES DO NOT NECESSARILY MEAN MAXIMUM STRENGTHS WHENEVER SOIL-AGGREGATE MIXTURES CONTAINING VARYING PERCENTAGES OF SOIL NEAR THE OPTIMUM ARE COMPARED. THE TESTS ON MIXTURES OF SOIL AND CRUSHED STONE RESULTED IN THE HIGHEST DENSITY AND STRENGTH VALUES OF THE MATERIALS, WITH THE SOIL-GRAVEL, SOIL-SAND, AND SOIL-DUNE SAND MIXTURES RESULTING IN THE NEXT HIGHEST VALUES IN THE ORDER GIVEN. INSOFAR AS DENSITIES AND STRENGTHS ARE CONCERNED, A SMALL QUANTITY OF SOIL MIXED WITH GRANULAR MATERIALS IS DESIRABLE, BUT LARGE QUANTITIES ARE DETRIMENTAL. /AUTHOR/
