Problem 135 in the NCEES Civil Practice Exam for Geotechnical refers to a type of soil density test that is commonly performed in the lab called Proctor testing. We’re going to walk through why the problem gives the measurement values that it does, which should help you put this type of problem into perspective since there are no figures or diagrams provided. While soil density test calculations are not very technically complicated, they can be abstract if you aren’t familiar with the test methods so the video provides a relevant photo example that helps explain this type of density test. Give this problem a try and then watch the video to see if your assumptions about the test method and the inputs provided were correct, good luck! - Mike Batten, PE - DTC Civil Geotechnical Instructor
