A VACUUM SATURATION METHOD FOR PREDICTING THE FREEZE-THAW DURABILITY OF STABILIZED MATERIALS

A STUDY WAS CONDUCTED TO DETERMINE IF A VACUUM SATURATION PROCEDURE COULD BE USED AS A RAPID AND ECONOMICAL METHOD FOR ACCURATELY PREDICTING THE FREEZE- THAW DURABILITY OF STABILIZED MATERIALS SUCH AS SOIL- CEMENT, LIME-FLYASH, AND LIME-SOIL MIXTURES, THE SOILS USED IN THE STABILIZED MIXTURES WERE REPRESENTATIVE OF THOSE FOUND IN ILLINOIS. VACUUM SATURATION WAS ACCOMPLISHED BY ALLOWING SPECIMENS, WHICH HAS PREVIOUSLY BEEN EXPOSED TO A VACUUM PRESSURE OF 24 IN. OF MERCURY FOR 30 MIN. TO SOAK IN WATER FOR 1 HR AT ATMOSPHERIC PRESSURE. FREEZE-THAW CYCLES WERE ACCOMPLISHED WITH AN AUTOMATIC FREEZE-THAW CABINET PROGRAMMED TO SIMULATE A REALISTIC FREEZE-THAW CYCLE. UNCONFINED COMPRESSIVE STRENGTH AND MOISTURE CONTENT MEASUREMENTS WERE USED TO EVALUATE THE DURABILITY OF THE STABILIZED MATERIALS. LINEAR REGRESSION ANALYSES OF THE DATA INDICATED THAT THERE WAS A SIGNIFICANT CORRELATION BETWEEN VACUUM SATURATION STRENGTH AND CYCLIC FREEZE-THAW STRENGTH. A SIGNIFICANT CORRELATION WAS FOUND TO EXIST BETWEEN VACUUM SATURATION MOISTURE CONTENT AND CYCLIC FREEZE-THAW MOISTURE CONTENT. BASED ON THE EXCELLENT CORRELATION BETWEEN THE VACUUM SATURATION STRENGTH AND MOISTURE CONTENT AND THE STRENGTH AND MOISTURE CONTENT AFTER FIVE AND TEN FREEZE-THAW CYCLES, IT WAS CONCLUDED THAT VACUUM SATURATION PROVIDED A RAPID AND ECONOMICAL METHOD FOR PREDICTING THE FREEZE-THAW DURABILITY OF STABILIZED MATERIALS.
