    Abstract: Disclosed are devices and methods using same for taking surface samples of bulk materials or loose materials for testing purposes (e.g., presence of pathogens, microorganisms, contaminants, etc.) in a manner that improves efficiency, reliability, repeatability, and case of use. The methods and devices provide for protecting the sample from accidental outside contamination by providing for immediate placement of collected pieces of material into a protected sampling container or collection space. The methods and devices require less hand-eye coordination skill than using a knife, and are thus more easily used by workers and/or by robots to achieve consistent results.

    Abstract: A multifunctional and modular geotechnical testing device for testing a soil sample is provided. The testing device includes a testing cell, a plurality of needle probes, and a plurality of lateral pressure-measuring sensors. The testing cell has an oedometer ring for accommodating the soil sample, with a plurality of holes located on and angularly distributed over an internal lateral surface of the oedometer ring forming a plurality of channels to access the soil sample from outside. The plurality of needle probes, each configured to house a pore water pressure-measuring sensor, is detachably mountable to the plurality of channels from outside for simultaneously measuring the pore water pressures. The plurality of lateral pressure-measuring sensors is removably attachable to an inner peripheral side of the testing cell for measuring lateral pressures of the soil sample.

    Abstract: A sample confinement tool includes a first end and a second end. The first end of the sample confinement tool is coupled to a driving tool. The driving tool is coupled to a heavy-duty vehicle. The sample confinement tool is operable to insert a predetermined depth below a ballast surface and collect a ballast sample within the second end of the sample confinement tool. The sample confinement tool is also operable to confine the ballast sample within the second end of the sample confinement tool by mechanically compressing the ballast sample. The sample confinement tool is further operable to release the ballast sample into a sample receptacle by mechanically decompressing the ballast sample.
