What does it mean to chuck ballast?
Dress means to add more to level it off, I know tamp means to press it down with force or weight, which is also done with asphalt. I imagine if you wanted to do something with sand ballast & a machine you could vibrate it somehow or vacuum it up and reapply, neither would work well unless your railroad is built on a sand deposit. If you put gravel on top of sand I would imagine you would get a lot of settling.
