    Abstract

    The evaluation of the potential durability of rock materials in a cold climate is dependent upon a complete understanding of both the environmental conditions of exposure and the mechanics of the freeze-thaw deterioration. Information related to the three types of mechanical processes which result in deterioration of rock materials is presented. The four environmental factors and the three physical property factors which control the three mechanical processes are also discussed. It is shown that because of the variability of the controlling factors and their effect on the mechanical processes, it is extremely difficult to predict the potential durability of any rock used for erosion control. It is concluded that additional study is needed in development of a series of index tests which will provide a suitable/not suitable rating for use in a particular environment.
