sand and salt mix in brick pavours

[leafyman]

Hi,
The sand in my brick drive needs renewing. I vaguely remember that mixing salt in with the new sand will help keep the weeds at bay. Is this right?

So what type of sand and what type of salt will I need?

Kiln dried sand and cheapest salt you can source , (just burns plant life).
