| Description | The objective of this study is to propose a laboratory element test for evaluating the air-permeability of unsaturated soils subjected to freeze-thaw action and to examine the effects of freezethawing and moisture content on air-permeability of unsaturated soils. This study develops a new test apparatus and perform a series of air-permeability tests for unsaturated soils under various freeze-thaw histories and moisture contents. As the results, it was revealed that the test device could evaluate airpermeability of geomaterials. Besides, it was recognized that though the difference in coefficient of air permeability before and after freeze-thaw were not observed in non-frost susceptible sand, the air-permeability of frost susceptible volcanic cohesive soil differs according to the moisture content and freezing rate. This indicates that the freeze-thaw action has strong influences on the air-permeability of frost susceptible geomaterials in unsaturated condition.
