Abstract
Regarding pavements in cold regions, it has been reported that vertical stresses in the ground at the depths where water or gas pipes are buried greatly changes along with the freeze-thaw cycling. In addition, it has also been revealed that incremental stresses in the ground due to vehicle wheel loads from the road surface changes along with freezing and thawing.<br> In this study, we investigated the effects of freezing and thawing under pavement on the relationship between the magnitude of the wheel load and the incremental stress in the ground, using vehicles of two types, which were of greatly different weights. We also investigated the effects of freezing and thawing on the stress distribution (transmission) in the ground, using a large scale soil container to simulate a paved road.<br> As a result, we found that the incremental stress in the ground increases with the vehicle weight and that the rate of increase changes with freezing and thawing. The stress distribution in the ground was also found to change with freezing and thawing.
