Here is my 2 cents worth:
1) The first thing to understand is the difference between crushed stone and gravel.
Crushed stone come from a rock quarry. The stone is dynamited, then crushed to different sizes. The product you want is a "3/4" or 1" with fines". When you drive on a "gravel" road, it is actually a crushed stone road.
Gravel comes from a pond or a river.
2) Some people will place 1" or 3/4" clean stone for a driveway. This does not have any "fines" or small particles in it. It looks great when it is intially placed. The problem with this installation is that it does not drain the water away properly. In the spring and fall when you have freezing and thawing it ends up being a mess!
3) What you want to do is look in the Yellow Pages under Crushed Stone. The companies listed here typically are tandem dump truck owner/operators. Tell them what you want completed. They will tell you roughly how many tons it will take and give you a $/ton.
The most cost effective way to place the crushed stone is to "trailer" the loads of rock down your driveway. Basically, the dump truck raises his box as heads down your driveway and spreads the rock as he goes. He can lock tailgate so it spreads about 3"-4".
You may need a skid loader to fine tune some of the areas. Once the stone is placed and graded, a vibratory roller should compact the stone. Most of the companies haul crushed stone also have skid loaders and compactors or know of someone who does. Have them include this cost in their $/ton.
4) Most driveways are at least 10-11' wide. So lets go with 4" thick, 11' wide x 660 feet long. To calculate the tonnage need: Length x width x thicknessx1.7/ 27=tonnage
11'x.333'x660'x1.7/27 = 152 tons
The 1.7 converts cubic yardage to tons and includes a waste factor. The 27 converts cubic feet to cubic yards.
5) The key to any road is to get the water off it and into properly draining ditches!
6) The cost of crushed stone varies from quarry to quarry. Also your distance from the quarry will effect the hauling price. Plus diesel fuel is over $4/gallon!!!! Yikes!
The cost of 3/4" crushed stone at a local quarry is $6.5 + sales tax. Assuming the distance from the quarry to your place is about a 45 minute round trip, and adding some cost for fine grading, and compacting, you are looking at about $12/ton. You are looking at about $1800.00
7) Take the $1800, drive to NY nonstop and buy an hour with one of those top of the line escort services!
