Show activity on this post. I looked at the gravel you are using. I would suspect you might see 1/2 to 3/4 inch of compaction, especially if you just laid it down. All you can do is start compaction, see what it looks like and add or rake off a bit to meet you needs. Pretty subjective answer, sorry.
