Analysis of the thermal stability of an embankment under different pavement types in high temperature permafrost regions

The thermal stability of the embankment, including the influence of the height and width of the embankment in high temperature permafrost regions was simulated and discussed respectively in terms of different natural geographic conditions for asphalt concrete pavements and cement concrete pavements. The aim is how to change the maximum thawed depth under the asphalt concrete pavements and cement concrete pavements with increase in service life and embankment width. The simulated results based on the observation of data from the Zuimatan of G214 road are analyzed in this paper. It is very important to select a suitable embankment width and height in high temperature permafrost regions, especially under the climate warming conditions. The conclusion that 2.0 m embankment height for the 8.5 m embankment width and 2.5 m embankment height for the 12.0 m embankment width are the most suitable for the cement concrete pavement construction in the experimenting road, respectively.
