Gravel Question
A good surface to drive on is like building a building to last. It begins with the foundation. First task is an evaluation of your existing conditions. What type of soils are in place? Clay, loams, rock, or whatever. This will determine water percolation. Next comes gradient. First lesson I learned in Landscape Architecture is that water runs downhill. Is the terrain relatively flat or is there side drainage to take the water off? Your existing conditions will determine how much grading is necessary to get rid of water and how many courses of what type of material you need to lay down. Wet, soggy existing conditions may require a deep base of large rocks, followed by crushed gravel ranging from one inch to 3/4 inch, and then finishing with what we in New Mexico call Base Course. The base course will compact and provide a nice driving surface because it has small gravel mixed with fines which help with the compaction. Just remember the water has to go somewhere. You will be happiest if you take the time up front to study the conditions and spend the money to do it right the first time. Best wishes.
