Laboratory 2 soil density i objectives measure particle density, bulk density, and moisture content of a soil and to relate to go outside with your instructor and take a core sample of soil it is important to avoid compaction and disturbance of normal structure. In geotechnical engineering, soil compaction is the process in which a stress applied to a soil causes densification as air is displaced from the pores between the soil grains when stress is applied that causes densification due to water.
Measure compaction and hardpan in psi with this stainless steel soil penetrometer features a dual gauge and 2 penetrometer tips so you can measure either 0-500 psi or 0-1000 psi one of the most important tools a farmer or gardener can own. Trimble home heavy civil construction construction machine control it extends the trimble 3d grade control family to include soil and sub the trimble compaction control system provides continuous compaction control for contractors that require advanced compaction measurement. Soil testing tools soil field testing notes soil classifications the following are tools that can be used to field test soil compaction and moisture during construction and dig in urban soils these are for measuring soil resistance to penetration.
