Title: COMPACTION CHARACTERISTICS OF SOIL-LIME-FLY ASH MIXTURES
Accession Number: 00230497
Record Type: Component
Abstract: FIELD COMPACTION IS ONE OF THE MOST IMPORTANT STEPS TO SUCCESS IN THE STABILIZATION OF SOILS. THERE ARE SEVERAL FACTORS THAT INFLUENCE COMPACTION, INCLUDING WATER CONTENT, AMOUNT OF COMPACTION, TEMPERATURE OF MIX MATERIALS, AND EFFECT OF DELAY IN COMPACTION AFTER MIXING. A LABORATORY INVESTIGATION WAS MADE TO STUDY THESE FACTORS USING FOUR SOILS, THREE FLY ASHES, AND ONE LIME. SPECIMENS WERE MOLDED NEAR STANDARD AND MODIFIED AASHO COMPACTIVE EFFORT AND MOIST CURED UP TO 90 DAYS. THE RESULTS INDICATE THAT THE BEST COMPACTING MOISTURE FOR MAXIMUM STRENGTH IS TO THE DRY SIDE OF THE OPTIMUM MOISTURE FOR MAXIMUM DENSITY IN THE SANDY SOIL AND ON THE WET SIDE IN THE TWO CLAYEY SOILS. THE TEMPERATURE OF THE MATERIALS DOES NOT HAVE A MARKED INFLUENCE ON THE STRENGTH. OF PARAMOUNT IMPORTANCE IS THE MINIMIZING OF THE DELAY BETWEEN WET MIXING AND COMPACTION OF THE SOIL-LIME-FLY ASH MIXTURES WHEN THE SOIL CONTAINS CLAY PARTICLES THAT CAN REACT WITH LIME, LOWERING THE DENSITY AND STRENGTH FOR THE SAME COMPACTIVE EFFORT. THE MODIFIED COMPACTIVE EFFORT GAVE STRENGTHS FROM 50 TO 160 PERCENT HIGHER THAN THE STANDARD. /AUTHOR/
