Any more and it is over kill. They use 3000 on almost every street over here. I would definitely use either the fiber mesh or some type of wire. The fiber mesh is a $6 adder over here and it comes out real close to a wash on cost compared to wire. Just regular vehicles, 3 1/2" is enough. If you go back to semi's, 6" would be required. Typcially, for regular flatwork (3 1/2") you can take your total sf and divide by 81 in a perfect world for your yards needed, but I would use 75 is the number to divide to make sure you have enough. Or use 81, but round up.

You obviously know a lot more about concrete than I do but why do you use 81 and 75 to divide by. 81 corresponds to 4" thick and 75 corresponds to 4.35" but why not just Length X Width X Thickness in ft divided by 27. You can always round up or just order 10% extra. Just wondering.
