A Basic Study on Frost Susceptibility of Rock: Differences between Frost Susceptibility of Rock and Soil
In this paper, we report the differences between frost susceptibility of rock and soil. Our research consists of two types of frost heave tests. One test uses solid rock samples. The other uses artificially-shattered, grainy rock samples. Rock can be treated as soil by artificially shattering. We conducted these two types of frost heave tests on 5 types of rock to investigate the differences between frost susceptibility of solid rock and grainy rock. From the test results, non-frost-susceptible rock did not change its frost characteristics in solid and grainy condition. On the other hand, the frost characteristics of frost-susceptible rock changed dramatically in solid and grainy condition. To determine the factors behind these test results, we compared the physical characteristics of solid rock sample and grainy rock sample. These comparisons clarified the structural difference between solid rock and grainy rock affects the frost susceptibility. These facts above indicate that the frost susceptibility of rock and that of soil are different.
