Wondering if anyone has used cast iron slag for roads and had sucess. Thanks in advance
Wind talk coming from the EPA is they are eyeballing slag due to the heavy metals. Also the same with fly ash. It may or not be something we see being banned in the future
John CAs I recall copper slag used to be used in this area all the time. EPA went back in a few years ago and made some people pick it up and dispose as hazardous waste. Seems it had a touch of arsenic in it.

The milling process for copper used arsenic in the slurry you could smell it. But I don't it was a large a mount.
