"Because of its size, texture, and color, pea gravel is typically used for more above-ground projects and applications." i.e., dog runs 'cause it doesn't - "With crushed stone, it’s important to consider its texture. Crushed stone can be easily tamped or rolled into place, which creates a more stable surface for areas such as driveways." – ozinga.com Crushed Stone vs. Pea Gravel - I prefer 3/4" minus or fines. Also, w/e it is needs compaction.

Sounds like you have a rather large hole - under the pipe, you want the good fill all the way to undisturbed soil so that it does not shift and is well supported. You'll want to tamp that, even with good fill. 6"/15cm to either side and above is adequate to buffer the pipe from the poor fill. Then again, you may have a minimum delivery size to get a pile of fill delivered, in which case you might as well use it (bagged fill material is absurdly expensive if you need more than a bag or two.)
