AN EXAMINATION OF METHODS OF DETERMINING THE SPECIFIC GRAVITY OF SOILS

THE RESULTS OF AN INVESTIGATION MADE TO FIND METHODS FOR THE DETERMINATION OF THE SPECIFIC GRAVITY OF SOILS THAT ARE LESS SUBJECT TO ERROR THAN THOSE GIVEN IN THE 1967 B.S. 1377 IS DESCRIBED. PART 1 OF THE REPORT SHOWS THAT THE PRESENT B.S. METHOD FOR COARSE-GRAINED SOILS CAN BE MADE MORE RELIABLE AND USED FOR ALL TYPES OF SOILS IF THE AIR IS REMOVED FROM THE SOIL BY A SHAKING TECHNIQUE IN PLACE OF REMOVAL UNDER VACUUM. IN PART 2 OF THE REPORT THE USE OF A LOEBELL AIR PYCNOMETER IS DESCRIBED AND IT IS SHOWN THAT THIS APPARATUS CAN BE ADAPTED FOR THE RAPID DETERMINATION OF THE SPECIFIC GRAVITY OF SOILS. THE TIME TAKEN IS LESS THAN 15 MINUTES AND THE ACCURACY IS SUFFICIENT FOR MOST PURPOSES. /RRL/A/
