I have a customer whose steep driveway was built with Caliche (crushed limestone). It's in bad shape and its slope is 10% or more. Caliche will hold up on this grade for a few years if it was compacted and traffic is light. But that quarry closed down a couple years ago and the nearest Caliche is too far for hauling here. Now most of us use granite road base, or hire Super Dumps to bring in Caliche, but that's expensive, or just process Caliche from a local private pit. Laborious.
Granite base is a much longer-lasting road. But for this customer I'm afraid it won't last on that grade, then my business will be associated with a failed driveway. I'd rather say no thank you. But try to educate the customer.
I'm looking for a document I can quote to the customer showing that gravel (road base) isn't appropriate for such a steep grade. Does anybody know of a source? I found this one but it's BS, trying to sell their stupid plastic crap that might last 2 months in Texas https://www.truegridpaver.com/gravel-driveway-on-a-slope/
I have a cat guy lined up to cut them a new road with a switchback, if they agree.
