REPORT OF COMMITTEE ON SOILS CALCIUM CHLORIDE ROADS

PREVIOUSLY REPORTED TESTS CONDUCTED AT PURDUE AND MARYLAND UNIVERSITIES HAVE SHOWN THAT ADDITION OF CALCIUM CHLORIDE PRODUCES A SUBSTANTIAL SAVING IN THE COMPACTIVE EFFORT REQUIRED TO OBTAIN A SPECIFIED DENSITY, INCREASES THE VALUES OF MAXIMUM DRY DENSITY, LOWERS BOTH THE LIQUID AND PLASTIC LIMITS OF SOME SOILS, AND RETARDS THE DRYING OF SOILS SUBJECTED TO ACCELERATED DRYING. DURING THE PAST TWO YEARS THE COMMITTEE HAS SPONSORED PROJECTS IN SEVERAL STATES TO CONDUCT TESTS ON SHEAR STRENGTH, MOISTURE, RAVELLING, FRIABILITY, BOND, AND DURABILITY AND PERFORMANCE. THE SHEAR TESTS CONDUCTED WITH BURGGRAF SHEAR APPARATUS ARE CONSIDERED OF SPECIAL IMPORTANCE. CONDUCTED UNDER A VARIETY OF CONDITIONS, THEY INDICATE THAT CALCIUM CHLORIDE PROMOTES LOWER RESISTANCE TO SHEAR AT EARLY AGES AND PROVIDES A DESIRABLE EXTENDED PERIOD DURING WHICH THE BASE COURSES REMAIN WORKABLE, PERMITTING THE COMPACTION TO BE EXTENDED OVER A LONGER PERIOD OF TIME OR UTILIZING THE CONSOLIDATING EFFECT OF VEHICULAR TRAFFIC.
