11-21. During construction, what check is performed  to  test  the  compactive effort? 1. Moisture  test 2. CBR test 3. Soil  compaction  test 4. Density  test 11-22. When  determining  in-place  density, which of the following methods should you use? 1. Penetration  method 2. Load-bearing  method 3. Nuclear   moisture-density meter  method 4. Hydrometer  method 11-23. Before  you  perform  the  sand- displacement  method  for  in-place density,  certain  calibration  must be performed. Which of the following  calibration  must  be completed? 1. Determine  the  jar  volume 2. Determine  the  sand  density 3. Determine  the  volume  of  the cone,  template,  and  surface irregularities 4. Each of the above 11-24. What is the depth of the hole for the  sand-displacement  method? 1. 5 inches 2. 6 inches 3. 3 inches 4. 4 inches 11-25. A  soil-sample  container  must be kept closed to prevent what problem? 1. Absorption  of  moisture 2. Sample  loss 3. Moisture  loss 11-26. What method is recommended to determine  the  moisture  content of a sample? 11-27. The  nuclear  moisture-density meter determines the moisture in the soil by what method? 1. Measures  the  hydrogen concentration  in  the  soil 2. Counts  the  gamma  rays  emitted 3. Measures  the  moisture evaporated  by  radiation 4. Measures oxygen in the soil 11-28. Before  operating  the  nuclear moisture-density meter, you must receive  specialized  training  and obtain  certification. 1. True 2. False 11-29.
