Thermal conductivities using the thermal probe method were determined for frost susceptible soil with three types of discarded tire powder under the condition of a temperature variation from $-20^{circ}C{sim}+10^{circ}C$. Also, the amount of unfrozen water contents was measured by the pulsed NMR method. The variation of unfrozen water content in the experimental condition could be expressed as a function of temperature given by an exponential equation. A new model for calculating the thermal conductivity of frozen soil was proposed. It is extended from the two element method and subdivided into three constituent elements.
