BINDERS FOR SNOW ROADS AND RUNWAYS IN ANTARCTICA
This is a study of the changes in the properties of snow when sawdust is added as a binder. A testing program evaluated data related to temperature profiles, density profiles, California Bearing ratio test, Clegg impact tests and Rammsonde penetrometer test. It was found that the strength of snow, as measured by the Ram penetration test, is increased when sawdust is used as an additive. The effect of sawdust was not as significant as anticipated due to the temperature effects. The use of sawdust may not be necessary in the construction of traveled ways in Antarctica, for below 15 cm, the necessary strengths were shown to be obtainable with a 100% snow mixture. Suitable construction techniques are required to form a homogeneous snow pavement. Also, adequate testing methods must be developed to measure the properties of high density snow pavements. The field material properties may then be related to the consititutive equation parameters.
