   I live in Northern Michigan and have owned my own brick paving company for 8 years. First of all the 15% grade should not be a problem with sand washing out if installed properly. Make sure that your road base gravel (preferably 8" or more) is compacted thoroughly. For the sand we have had our best luck with 1/2 to 1" of sand. I live in a hilly community and have installed many driveways steeper than yours with no problem of washout.

   Second, for a driveway in Minnesota I would definitely not use clay bricks. Their water absorption rates are two high and with the freeze thaw cycles they will crumble within a few years. Concrete pavers on the other hand, if installed properly, will outlast you. Good luck.

   and in winter ice, brick seem to always ice over before the concrete pavers (and asphault and poured concrete)

   Jumbo;s got it right installation of base is critical with good compaction. Stay away from clay pavers they will not hold up.  However if you can find some old street pavers that are being torn up  these would work as they are usually alot thicker and subject to abuse.  Usually clay pavers can be used for patios and porches.  Their is a paver called enidicot (sp.?) which is exteremly hard and probably would work if you have to have clay, but they are very pricey$$$. Check with your local brick yard and they should be able to help you.

   I have been installing pavers for 20 years.  I do not see a problem with your grade, but I would rather see 12" of crushed stone base.  2" stone with the fines for most of it, followed by 1" as you get close to grade.  Thin lifts, tamped frequently.  Ditto on the clay pavers.  Good luck with the project.
