Rock salt in enough concentration would kill off all the vegetation underneath it once it got wet. It would also leach into the soil and keep things from growing there for a number of years. You have to be very careful using it to make sure that it doesn't leach into the nearby soil or into any waterways. If you want my opinion, don't be cheap and buy some of the commercial-grade herbicide and use a moderate amount. If anything comes back, use it again. It's strong stuff, so you don't need much of it, but it should take care of anything you have. I'm using some of it under my deck, which is all gravel.
