REPORT OF COMMITTEE ON FROST HEAVE AND FROST ACTION IN SOIL

A SUMMARY IS PRESENTED OF THE FINDINGS OF THE ORIGINAL COMMITTEE WHICH WAS SET UP TO: (1) STUDY THE USES OF CALCIUM CHLORIDE AS AN ADMIXTURE WITH SOILS FOR MINIMIZING FROST HEAVE, AND (2) STUDY THE USE OF CALCIUM CHLORIDE MIXED WITH SUBGRADE SOILS TO MINIMIZE FROST ACTION AND THE RESULTING FROST DAMAGE TO PAVEMENTS. LABORATORY WORK INDICATES STRONGLY THAT CALCIUM CHLORIDE MIXED WITH SOIL WILL MINIMIZE OR ELIMINATE FROST HEAVE WHEN THE CALCIUM CHLORIDE IS USED IN SUFFICIENT QUANTITIES AND WHEN THE CHEMICALS ARE NOT LEACHED FROM THE SOIL UNDER CONDITIONS OF ADVERSE WATER FLOW. FIELD INSTALLATIONS OF CALCIUM CHLORIDE MIXED OR ADDED TO SUBGRADE SOILS HAVE BEEN MADE ON PROJECTS IN MINNESOTA, INDIANA, MICHIGAN, AND MASSACHUSETTS IN AREAS WHERE SEVERE FROST HEAVE OR FROST DAMAGE HAVE BEEN NOTED. IN SEVERAL OF THE INSTALLATIONS NO APPARENT BENEFIT RESULTED FROM THE USE OF THE CHEMICAL TO MINIMIZE FROST HEAVE. DATA COLLECTED INDICATE THAT IN SOME OF THESE CASES, ADVERSE WATER CONDITIONS MAY HAVE BEEN RESPONSIBLE IN PART FOR THE FROST HEAVE. THESE ADVERSE WATER CONDITIONS MAY HAVE BEEN LARGELY RESPONSIBLE FOR LEACHING THE SOLUBLE CHEMICAL FROM THE TREATED SUBGRADE. A PROGRAM IS BEING DEVELOPED TO DETERMINE THE EFFECTIVENESS OF CALCIUM CHLORIDE IN SUBGRADE AND BASE COURSES FOR THE PURPOSE OF MINIMIZING THE AMOUNT OF BREAK-UP WHICH OCCURS ON SOME ROADS DURING THE SPRING OF THE YEAR BECAUSE OF SATURATION OF THE SUBGRADE DURING THE MELTING PERIOD.
