That Type 3 aggregate (4/20) does not compact anywhere near as much as you might expect. The lack of fines means it isn't "fluffed up" like a Type 1 or Type 2 aggregate, so needs less in the way of compaction.
Although you could use a roller, if you can get a 75kg+ plate compactor, and whack it in layers of 100mm at a time, that will do the job just as well as a half-tonne roller.
