THE RELATION OF CERTAIN FROST PHENOMENA TO THE SUBGRADE

PAVEMENT CONDITION STUDIES DEMONSTRATE THE NEED OF RESEARCH PERTAINING TO FROST ACTION ON SUBGRADE SOILS. OVER 50 PER CENT OF ALL PAVEMENT FAILURES ARE ATTRIBUTED TO DIFFERENTIAL HEAVING OR EXPANSION OF SUBGRADE ON FREEZING. FIELD STUDIES DISCLOSE POSSIBILITIES OF RECOGNIZING SOIL PROFILES, CONDITIONS, TEXTURES AND ASSOCIATIONS DANGEROUS FROM THE STANDPOINT OF EXCESSIVE HEAVING. FIELD RESULTS SHOW THAT EXCESSIVE HEAVING VERY OFTEN OCCURS IN SOILS OF PARTICLE SIZE LARGER THAN THAT IN WHICH SEGREGATION OCCURS IN LABORATORY. RECENT LABORATORY INVESTIGATIONS IN MICHIGAN INDICATE THAT ALTERNATE FREEZINGS AND THAWINGS OF SUBGRADES BENEATH THE GROUND SURFACE MAY BE THE PRIMARY CAUSE OF EXCESSIVE HEAVING IN SOILS HAVING A PARTICLE DIAMETER SIZE LARGER THAN .005 MILLIMETERS. THE RESULTS OF INVESTIGATIONS ARE PUT IN PRACTICE. OVER TWO HUNDRED LOCATIONS WERE GIVEN SPECIAL TREATMENT TO PREVENT SUBGRADE HEAVING DURING 1930.
