The thermal conductivity of a material is the parameter that is most reliably determined experimentally. The problem of determining the thermal conductivity in the soil is greater because the soil is heterogeneous, so for the same soil this parameter may be different depending on the their ohysical characteristics. Therefore, it is necessary to adopt an appropiate model for describing the thermal conductivity of the soil for a particular location after the necessary tests are performed. This paper is based on experimental measurements of soil thermal conductivity as a function of moisture content in the area of the ,Nikola Tesla Airport construction site in Surčin and the adoption of one of the existing theoretical models that would satisfactorily describe changes in thermal consuctivity. Based on the obtained results of experimental reasearche, a two- parameter fitting of the measured values of thermal conductivity of the soil was performed in Cote-Konrad model, which proves to be rel...iable and the simplest to describe the thermal properties of loess in the area of Belgrade.
