Hello –
Thanks for the question. There is alot there to talk about! I have posted an excerpt from NEAL that goes over this formula. FOllow the link below. You can also use the pavemanpro mix design calculator once you get a handle on it. It is highly accurate, and will also help answer your questions. The spec sheets for the material you use will also give you information on coverage rates and mix designs that relate specifically to that material. They are a great resource and will also help you with this stuff.
Check out the link below. This info will give you insight into the formula.
