Practices for Field and Laboratory Evaluation of Thermal Resistivity

In the design of heat generating underground utilities, such as electrical conduits, understanding the ability of the surrounding media to dissipate heat is a key parameter for design. Thermal resistivity, referred to as Rho (ρ) value and expressed in units of C.Cm/W or C.m/W, is the measure of resistance to heat flow through a material such as soil, concrete, or Fluidized Thermal Backfill (FTB) used as backfill or encasement for underground utilities.
