FROST HEAVE MEASUREMENTS OF LIME-MODIFIED SOIL FROM THE OTTAWA AREA IN THE LABORATORY

During the construction of Highway 417 in the Ottawa area between 1976 and 1979, considerable amounts of clayey material were treated with high-calcium lime to improve the workability, most ot the treatment being carried out using small percentages of lime and a "cut-and-fill" technique. Frost heaving occurred in numerous areas along the highway during the winter of 1978-79, principally between Highway 17 and Goulborn Rd. (Reg. Rd. 16), with severe pavement distortion resulting. Ice lenses were observed in a couple of test pits, and in the spring, large amounts of water appeared in and around the areas of maximum heaving. Data on the frost heaving characteristics of these lime modified materials was obtained using the laboratory facilities of Ontario Hydro. It is now apparent that the frost heaving characteristics of these materials should be studied in conjunction with the other design parameters to allow more successful implementation in field problems.
