Webb19 juli 2024 · Zoom proctoring offers you an option to proctor exams remotely. This intuitive tool has no limitations- you can proctor several exam sessions at a time. If all the students take the exam synchronously, instructors can set separate zoom meetings for the students to create small groups. A representative bulk field sample is obtained for each type of soil material proposed for use in the earthwork operation. Weights required for the bulk sample will range from about 50lb to 100lb (23kg to 45kg) of the moist sample, depending on the test method specified.
