If it's a general cold mix, yes it can be moved for quite a while after dumping or stockpiling. Via the name cold mix.Alot easier to work with, and after desired leveling, get in your truck and roll it with your tires without twisting back and forth (neumatic roller with alot less tires). When your finished and still don't like the appearance, then rent a flat type roller. This is how Hot Mix helps get density or compaction before the finish roller (or flat) gets on it so no damage will be done. You won't hurt it, but remember cold mix will stay tender, especially in hot weather and takes a long time to cure. That's why different grades of asphalt cement are made like hot mix to make it short. Don't be afraid of it. I used it in my drive and when not at home I make it. Funny your friend never told you that.
