Abstract EN
The permafrost degradation is the fundamental cause generating embankment diseases and pavement diseases in permafrost region while the permafrost degradation is related with temperature.
Based on the field monitoring results of ground temperature along G214 Highway in high temperature permafrost regions, both the ground temperatures in superficial layer and the annual average temperatures under the embankment were discussed, respectively, for concrete pavements and asphalt pavements.
The maximum depth of temperature field under the embankment for concrete pavements and asphalt pavements was also studied by using the finite element method.
The results of numerical analysis indicate that there were remarkable seasonal differences of the ground temperatures in superficial layer between asphalt pavement and concrete pavement.
The maximum influencing depth of temperature field under the permafrost embankment for every pavement was under the depth of 8 m.
The thawed cores under both embankments have close relation with the maximum thawed depth, the embankment height, and the service time.
The effective measurements will be proposed to keep the thermal stabilities of highway embankment by the results.
