Berm drainage ditches may fail due to frost heave in cold and snowy areas like Hokkaido. Many of these failures are regarded to be caused by damage due to frost heave in the ground or freeze-thaw, but no sufficient measures are being taken, as construction guidelines and procedures do not describe any established countermeasures for the damage. Therefore, it was decided to study countermeasures by utilizing berm drainage ditches that can change form in response to frost heave, rather than by trying to reduce the level of change caused by frost heave. A drainage ditch made of flexible asphalt sheets was constructed on site, and the soil temperature, frost penetration depth, frost heave amount, and other parameters were measured. As a result, it was found that a drainage ditch made of asphalt sheets is more effective when ground conditions including moisture and temperature are severe in relation to frost heave.
