Likely a mixture of these answers, though if you want to wait for an expert to weigh in maybe ask for that. A roadway is obviously a very different environment with a lot of money and research put into ensuring it can handle a lot of traffic and weight, having to accommodate worst case scenarios so it’s obviously going to have a very strong base, and a comparitively very durable and thick base of asphalt. Your driveway, on the other hand, is probably going to be covered in a mixture very much driven by price. If you do the minimum underlayment and thickness, you’re probably going to need to give it every advantage possible to avoid rework.




Funny thing is even that number would be based on all the people who can pay 20 but not 800. If it all has to be balanced by the users it would probably be an order of magnitude… Or the market would play like it logically should and it would be like 3 companies paying a million a month. But what would they do with it? Sell it at a loss for like 20 per user and hope they figure out some way to make money :)
