Engineering parameters of rocks mostly depend on internal properties such as mineralogical composition and texture. Physical and chemical processes can cause changes in these engineering parameters. Freeze-thaw is one of the most detrimental phenomena affecting rock properties. This study focuses on the effect of freeze-thaw cycles on the engineering properties of sedimentary rocks. The degree of alteration in the rock, type of cement and the presence of fossils were decisive on rock disintegration during freeze-thaw cycles. Models from two different studies that investigated the weathering behavior under freeze-thaw cycles were applied to the test results of this study. Simple and multiple regression analyses were performed on the test results to predict the UCS values of rocks after 25 cycles, using the results of simply applicable tests at the initial conditions without having to conduct tedious and destructive freeze-thaw tests.
