520 3# ‡aEvaluates two surface modification techniques to reduce permafrost degradation below roadway embankments. Snow management on side slopes showed 20% increase in freezing n-factor. Placing quarry rock to depth of 1.3m on side slopes gave increase in freezing and decrease in thawing n-factors of 150%, respectively. Mean annual soil surface temperature was reduced by 8°C.
