When taking an in-place field density testing on an FAA P-401 spec, do you use the theoretical maximum density (rice value) or the bulk specific gravity (marshall value as the others in my office call it). I have done 3 different airport jobs on the east coast and I always used the rice value in the field. One of the engineers said that was wrong since you are comparing the cores with the marshall value in the field and not the rice value. Any links would be helpful since they wont believe it unless i show them proof.
