Got a problem with a gravel access road. It is only about 1000 feet long, but depends into and out of a small gulley to serve three residences. The slope is up to 10 percent. The road has had the problem with washboard in and tuts. As a result, one of the owners put 2 to 3 inches of 3/4" minus over the top and tried to compact it. Now it is worse than ever, and I had to call a towtruck to be pulled out last night.
My question is, without totally redoing the road, can the addition of 1.5" minus compacted stabilize the 3/4" layers so that you can get sufficient traction to climb the grade without spinning wheels?
Fyi, the alignment is of a poor design with a sharp curve at to one side of the gulley, making adequate momentum difficult to msintain.
