Research is reported which examined several factors that influence the thermal resistivity of soils in light of their use in geotechnical engineering applications. The study refined the thermal needle method for measuring the thermal conductivity of soil, and investigated the influences of water content, temperature, compaction water content, and time on the thermal resistivity of sands. It is noted that if a sand is to be used as insulation, then the sand should be poorly graded, mica-rich; and dry density and water content at compaction should minimized. If heat transfer is to be maximized, the sand should be quartz-rich and well graded; and dry density and water content at compaction should be maximized.
