Title: PREVENTION OF DETRIMENTAL FROST HEAVE
Accession Number: 00237911
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: FROST HEAVE OCCURS AFTER WATER FREEZES IN LAYERS OR LENSES IN CERTAIN SOILS AND WHEN THE LAYERS GROW UNDER PROLONGED FREEZING ACTION. THE QUANTITY OF MOISTURE CAPABLE OF BEING RAISED TO A GIVEN HEIGHT ABOVE THE WATER TABLE IN A GIVEN TIME DETERMINES WHETHER FROST HEAVE WILL OCCUR. IN ORDER TO FURNISH CAPILLARY MOISTURE IN DETRIMENTAL AMMOUNTS, THE PORE SIZE MUST BE SMALL ENOUGH TO SUPPLY CAPILLARY PRESSURE AND YET LARGE ENOUGH TO PREVENT TOO MUCH FRICTIONAL RESISTANCE TO FLOW. VERY FINE SANDS AND SOILS, GRADED SOILS (CEMENTED SOILS), HARD PANS OR GLACIAL TILLS TEND TO CAUSE FROST HEAVES. PREVENTION REQUIRES THAT: THE FOUNDATION CONDITIONS ARE KNOWN BEFORE THE ROAD IS DESIGNED; THE HIGHWAY DESIGN CONTAINS CORRECTIONS FOR FOUNDATION IRREGULARITIES; AND CONSTRUCTION METHODS ADHERE TO THE DESIGN AND ACT AS A CHECK ON SOIL SURVEY IRREGULARITIES. EXPERIENCE HAS SHOWN THAT BY REMOVING THE FROST HEAVING MATERIALS AND CONSTRUCTING A BASE COURSE OF NONFROST HEAVING MATERIALS FROST ACTION CAN BE CONTROLLED. UNDERDRAINS CONSTRUCTED AT DEPTHS THAT EFFECTIVELY REMOVE WATER FROM THE FROST PENETRATION LINE ARE USED TO CUT OFF SIDE HILL SEEPAGE OR TO LOWER EXISTING GROUND WATER TABLES. A BRIEF DISCUSSION IS PRESENTED ON THE PRACTICES OF DETRIMENTAL FROST HEAVE IN NEW HAMPSHIRE, MICHIGAN, AND WASHINGTON.
