If the native soil is to be tamped back into the trench at the same density at which it was removed, it may be desirable to make in-situ resistivity measurements along the route of the cable. If the native soil is to be placed in the trench at a density different than undisturbed soil in the same vicinity, laboratory measurements are required on soil samples recompacted to the desired density. In order to draw meaningful comparisons on selected foreign backfill materials, thermal resistivity measurements should be made in the laboratory on soils which are compacted so as to provide maximum dry densities.

          The measurement of thermal resistivity of soil and backfill materials to include concrete, engineered backfills, grout, rock, sand, and any other material used to encase the cable system installed in the ground is covered in this guide. A thorough knowledge of the thermal properties of a soil or backfill material enables the user to properly design, rate, and load underground cables. The method used is based on the theory that the rate of temperature rise of a line heat source is dependent upon the thermal constants of the medium in which it is placed. The designs for both laboratory and field thermal probes are also described in this guide.<br />\n
