PORE SIZE AND FIELD FROST PERFORMANCE OF SOILS

IT IS SUGGESTED THAT THE SOIL PROPERTY ESSENTIALLY DETERMINING FROST BEHAVIOR IS PORE-SIZE DISTRIBUTION. THE EXISTING FROST SUSCEPTIBILITY CRITERIA ARE, HOWEVER, BASED ON GRAIN-SIZE CHARACTERISTICS. ON THE BASIS OF THE FIELD FROST PERFORMANCE OF 126 ONTARIO HIGHWAY SUBSOILS, THE RELIABILITY OF SEVEN EXISTING FROST SUSCEPTIBILITY CRITERIA IS ANALYZED. THE RESULTS INDICATE THE LIMITATIONS OF THESE CRITERIA. A SIMPLE METHOD IS DEVELOPED TO DETERMINE THE PORE-SIZE DISTRIBUTION OF SOILS, AND A TENTATIVE FROST SUSCEPTIBILITY CRITERION BASED ON THIS SOIL PROPERTY IS ESTABLISHED. THE RELIABILITY OF THIS CRITERION APPEARS TO BE MORE SATISFACTORY THAN THAT OF THE EXISTING CRITERIA. THE POSSIBILITIES FOR FURTHER RESEARCH WORK ARE INDICATED. /AUTHOR/
