  • How much volume is lost after compacting 3/4" crushed stone?

    The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4" stone will be about 80-90% depending on the stone (angularity and phi). Presuming that you are compacting to 100% of some form of "proctor density", because you're awesome at compacting and have a monster machine (and thin lifts), that's 100/80=125%.
