THIS INVESTIGATION EXAMINES THE CHARACTERISTICS OF IRREGULARLY SHAPED COMPACTION CURVES. ON THE BASIS OF A SERIES OF TEMPERATURE-CONTROLLED EXPERIMENTAL TESTS, SEVERAL CONCLUSIONS ARE REACHED. THE INVESTIGATED VARIATION IN TEMPERATURE PRODUCES NO SIGNIFICANT INFLUENCE FOR ALL THE SOILS AT LOW WATER CONTENT. THE RANGE OF WATER CONTENT SHOWING NEGLIGIBLE TEMPERATURE EFFECTS IS FROM 0 TO 7 PERCENT FOR SOILS WITH A LIQUID LIMIT LESS THAN 30 AND A WATER CONTENT FROM ABOUT 7 PERCENT TO THE OPTIMUM POINT AND SOILS WITH A LIQUID LIMIT GREATER THAN 70 AND A WATER CONTENT FROM ABOUT 15 PERCENT TO THE SATURATION POINT. THE INCREASING TEMPERATURE RESULTS IN AN INCREASE OF DRY DENSITY BECAUSE THE HIGHER TEMPERATURE IS ASSOCIATED WITH LOWER STRENGTH. THIS PHENOMENON TENDS TO DECREASE AFTER THE SATURATION MOISTURE CONTENT IS REACHED.
