DEVELOPMENT OF A FREEZE-THAW TEST FOR DESIGN OF SOIL-CEMENT

A LABORATORY TEST FOR EVALUATING THE DURABILITY OF STABILIZED FINE-GRAINED SOILS SUBJECTED TO REPEATED FREEZE- THAW CYCLES HAS BEEN DEVELOPED. TEST SPECIMENS /2-IN. BY 2- IN. DIAMETER/ MOLDED IN IOWA STATE COMPACTION APPARATUS ARE USED. THE SPECIMENS ARE KEPT FROZEN FROM TOP WITH FREE WATER AVAILABLE AT BOTTOM. WINTER CLIMATIC CONDITIONS IN IOWA ROADS ARE SIMULATED TAKING INTO CONSIDERATION FIELD CONDITIONS, SUCH AS A FREEZING TEMPERATURE, AVAILABILITY OF FREE WATER, AND A PROPER TEMPERATURE GRADIENT. CLIMATIC DATA AND FREEZE-THAW CALCULATIONS SHOWED THAT 10 CYCLES OF FREEZING AND THAWING ARE SUFFICIENTLY SEVERE FOR TESTING BASE COURSES. THE CRITERIA WERE THE UNCONFINED COMPRESSIVE STRENGTH AND THE INDEX OF RESISTANCE TO THE EFFECT OF FREEZING, DEFINED AS THE RATIO OF THE UNCONFINED COMPRESSIVE STRENGTH OF THE FREEZE-THAW SPECIMEN TO THAT OF THE IMMERSED CONTROL SPECIMEN. LABORATORY TEST RESULTS ARE CORRELATED WITH THOSE OF FIELD TRIAL SECTIONS OF SOIL-CEMENT BASE COURSES. BASED ON THE PERFORMANCE OF THE TEST SECTIONS IN WHICH THE CEMENT CONTENT WAS THE VARIABLE, AN ADEQUATE SOIL AND CEMENT COMBINATION WAS CHOSEN. THE LABORATORY TEST RESULTS OF THE SOIL-CEMENT ARE PROPOSED AS TENTATIVE CRITERIA FOR THE DESIGN OF SOIL-CEMENT FOR BASE COURSES. FROM THE RESULTS OF ONE YEARS STUDY OF THE EXPERIMENTAL PAVEMENT SECTIONS, 7 PERCENT CEMENT SEEMS TO BE ADEQUATE FOR MAKING DURABLE SOIL-CEMENT, THOUGH STANDARD TESTS WARRANTED 11 PERCENT CEMENT ADMIXTURE. /AUTHOR/
