USE OF CALCIUM CHLORIDE IN GRANULAR STABILIZATION OF ROADS

A CRITICAL REVIEW AND ANALYSIS OF THE AVAILABLE LITERATURE DEALING WITH THE USE OF CALCIUM CHLORIDE IN GRANULAR STABILIZATION OF ROADS HAS BEEN MADE AND AN ANNOTATED BIBLIOGRAPHY HAS BEEN PREPARED WITH COMMENTS ON THE SUBJECT OF EACH REFERENCE. CLASSIFIED AND AUTHOR INDEXES TO THIS BIBLIOGRAPHY HAVE ALSO BEEN MADE TO FACILITATE ITS USE. A NUMBER OF FACTS WERE BROUGHT OUT CONCERNING THE USE OF CALCIUM CHLORIDE, SUBSTANTIATED BY LABORATORY OR FIELD INVESTIGATIONS. THESE ARE: (1) CALCIUM CHLORIDE MIGRATES THROUGH SOIL IN THE FORM OF A SOLUTION, (2) THE RATE OF EVAPORATION OF MOISTURE FROM SOIL IS REDUCED BY CALCIUM CHLORIDE, THUS MAINTAINING THE MOISTURE THAT IS NECESSARY FOR THE DEVELOPMENT OF COHESION IN SOILS, AN ESSENTIAL OF STABILITY, (3) COMPACTION IS FACILIATED SO THAT THE DESIRED DENSITY IS OBTAINED WITH LESS COMPACTIVE EFFORT, (4) AGGREGATE LOSS IS REDUCED; (5) TREATED STABILIZED ROADS ARE LESS INCLINED TO DUSTING THAN UNTREATED ROADS; (6) THE DETRIMENTAL EFFECTS OF FREEZING ARE MATERIALLY REDUCED BY THE USE OF CALCIUM CHLORIDE; AND (7) MAINTENANCE BLADING AND UPKEEP COSTS ARE LESS ON CALCIUM CHLORIDE TREATED STABILIZED ROADS. /AUTHOR/
