Crushed concrete and asphalt in place of crushed stone for foundation drainage?

| Posted in Green Products and Materials on
I’m installing footing drains on my 1930s house. I’ve read all about how to do it and feel good about the process. I would like to use a recycled product like crushed concrete instead of stone as the back fill material. It’s cheaper and it reuses old material.
My question is about drainage: will it drain sufficiently? or should I stick with stone? Specifically, here’s what the company is offering. https://www.ewingstreetstone.com/

Some of the photos on the Ewing site show nice, open aggregate, which is what you want. Other photos show a lot of fines, which is not what you want.
Joel has it right; it's all about the fines.

i decided not to risk it, and went with round stone. i was afraid the concrete would create fines, if that makes sense.
