EXPERIENCES WITH SOIL-LIME MIXTURES IN SASKATCHEWAN

LIME STABILIZATION HAS ONLY RECENTLY BEEN USED IN WESTERN CANADA. THIS REPORT IS A BRIEF SUMMARY OF SOME OF THE FINDINGS IN SASKATCHEWAN. SOIL-LIME MIXTURES WERE SUBJECTED TO THE CALIFORNIA BEARING RATIO COMPRESSION TESTS AND CONSIDERED IN RELATION TO THE PLASTICITY INDEX. MOISTURE- DENSITY RELATIONS WERE ALSO INVESTIGATED AS WELL AS RELATION TO MOISTURE CONTENT, COMPACTION, DRY DENSITY, THE ADDITION OF SALT AND FREEZE-THAW EFFECTS. LIME ITSELF WAS FOUND TO BE UNSUITABLE AS A STABILIZING AGENT, HOWEVER, THE ADDITION OF SOME FLYASH GREATLY IMPROVED THE DURABILITY RESULTS. BECAUSE OF ITS HYDROPHILIC NATURE, TIME HAS A TENDENCY TO REDUCE THE AMOUNT OF FROST IN SOIL AND THUS REDUCE DAMAGE FROM FROST HEAVE. THE SOILS TESTED WERE MAINLY LACUSTRINE DEPOSITS AND GLACIAL TILL. THE RESULTS OF THE STUDY WERE APPLIED TO CONTROL SECTIONS IN THE HIGHWAY SYSTEM AND THE SECTIONS ARE NOW UNDER OBSERVATIONS. /CGRA/
