EFFECT OF MIXING AND AERATION ON SOIL-CUTBACK MIX DESIGN

LABORATORY TESTS WERE CARRIED OUT ON FOUR SOILS STABILIZED WITH CUTBACK BITUMEN GRADES RC-3, RC-2, MC-3 AND MC-2 TO FIND THE EFFECT ON STABILITY, WATER ABSORPTION AND SWELLING OF MIXING TEMPERATURE, MIXING PERIOD, AERATION TEMPERATURE AND AERATION PERIOD. INCREASING THE MIXING (AND COMPACTING) TEMPERATURE RESULTS IN HIGH STABILITY AND LOWER WATER ABSORPTION AND EXPANSION VALUES. THERE IS AN OPTIMUM MIXING PERIOD WHICH WOULD GIVE MAXIMUM STABILITY OR MINIMUM WATER ABSORPTION OR EXPANSION VALUES AT ANY GIVEN TEMPERATURE. AERATION OF THE MIX BEFORE COMPACTION INCREASES THE STABILITY AND DECREASES THE WATER ABSORPTION. THERE IS AN OPTIMUM AERATION PERIOD CORRESPONDING TO MAXIMUM STABILITY OR MINIMUM WATER ABSORPTION, DEPENDING ON TEMPERATURE, CUTBACK AND TYPE OF SOIL. /RRL/
