  • SYSTEMS AND METHODS FOR CONFINING BALLAST SAMPLES
    Publication number: 20220082475
    Abstract: In one embodiment, 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.
