AN ORGANIC COMPOUND AS A STABILIZING AGENT FOR TWO SOIL-AGGREGATE MIXTURES

LABORATORY INVESTIGATIONS INDICATED THAT CERTAIN ORGANIC COMPOUNDS WHICH FURNISH LARGE ORGANIC CATIONS WHEN DISSOLVED IN WATER HAVE CONSIDERABLE PROMISE AS ADMIXTURES TO INCREASE THE ALL-WEATHER STABILITY OF SOILS. AN INVESTIGATION IS DESCRIBED WHEREIN ONE PROMISING COMPOUND WAS EVALUATED AS A STABILIZING AGENT FOR TWO SOIL-AGGREGATE MIXTURES HAVING PLASTICITY INDICES HIGHER THAN CONSIDERED DESIRABLE FOR HIGHWAY SUBGRADE MATERIAL. THE TEST RESULTS INDICATE THAT WATER SOLUTIONS OF THE CHEMICAL ADMIXTURES HAD THE SAME QUALITATIVE EFFECT ON THE TWO SOIL-AGGREGATE SAMPLES. THE FOLLOWING PROPERTIES WERE DECREASED: PLASTICITY, SHRINKAGE, MAXIMUM MODIFIED AASHO DENSITY AND OPTIMUM MOISTURE CONTENT, AND UNSOAKED CALIFORNIA BEARING RATIO (CBR). THE SOAKED CBR OF BOTH SAMPLES WAS INCREASED AND SWELLING WAS REDUCED. /AUTHOR/
