This basic research was the first step towards the construction of a compacted-snow runway on the Antarctic ice sheet. In Rikubetsu, we constructed three test fields (20 m in length, 7 m in width, and 0.4-1.0m in thickness) on compacted basal snow (approximately 0.05m in thickness). First, 0.1-0.35-m-thick layers of snow were deposited on the basal snow of the fields using a rotary snowplow. Next, the surface snow was smoothed using an excavator. Finally, the snow layers were compacted four times using a bulldozer. This entire process was repeated three to four times in order to construct 0.4-1.0-m-thick test fields. The ram hardness, snow density, and snow structure of these fields were investigated. A comparison with criteria established by a U.S. scientist for a large aircraft\uff0dsuch as the C-130(Abele,1990)\uff0drevealed that if snow in the form of three 0.2-0.25-m-thick layers is compacted four times by a bulldozer, it is sufficiently hard to serve as a runway at H68(69\u00b011\u00b429\u2033S, 41\u00b003\u00b434\u2033E, 1204m a.s.l) for a wheeled C-130.
