Frost-heaving pressures
Test chamber used is designed to minimize friction of soil with wall; accurate control of heat removal is obtained by thermoelectric cooling; load cell placed on top of sample is used to measure pressure developed and at same time prevents heaving of sample; measurement of pressure on layered sample shows that pressure develops at freezing front; results on several soils indicate that each soil develops characteristic maximum pressure; for each soil used, water content vs tension curve is given and maximum pressure is related to this curve.
