Need some advice on how thick should asphalt or concrete driveways be constructed to allow a LARGE double dump transfer truck to pass without tearing up the roadbed. Here is the plan: I need to put in about ~800’ of driveway. The plan is the first 300’ will be concrete and the final 500’ will be asphalt. My neighbor has 3” of road base and 1.5” of asphalt and he no longer needs to steer his car once he is on his driveway. On a hot day last summer a large truck drove down to his house (per his insistence) and left a nice 2” deep furrow the length of his driveway. I have a trusted contractor. This is the third house he has built for me, but he is not experience in the problems associated with heavy trucks.
First the asphalt: This driveway extends from the main house to the barn. The driveway contractor tells me that 6” of road base covered by 3” of asphalt is more than enough to carry a double transfer truckload of rock without a worry. (25tons of rock plus whatever the truck weighs, my guess is 20,000lbs). I would appreciate some coaching from anybody who might have any experience with this?
Second the concrete: Part of the loop driveway in front of the house needs to be able to carry the same trucks so they can get the asphalt drive that extends down to the barn. Right now the plan is for 4” road base and 4” of fiber reinforced, 5-bag mix concrete. The driveway contractor says when you use the fiber mix, there is no need for steel in the concrete. I am leery of not having steel in the concrete. Again, I would appreciate some coaching from anybody who might have any experience with this?
Thanks in advance,
