No, you don't want to use that locker on the pavement. You shift out before you get there. The reason is that there are small differences in tire size etc that put tremendous force on the drive train when all tires get full traction. This gets exacerbated when you go around a corner and the tires can't slip a little. It gets even worse with a locker. If you don't break something, you will cause premature wear to occur.
