I am building a Fire Truck Access road (gravel) and the cross section is going to be something like 6" of 3/4" minus over 9" of 1-1/2" minus. I am building this road over adverse soils (saturated garbage fill, maybe clayey silty loom?? with zero percolation properties). My solution to this problem is to over excavate and replace with 4" minus. I can, out of the air, come up with a depth (of 4" minus) that will easily account for the adverse soils but I am tired of over designing (spending too much of the clients money). How does one calculate (and / or which soil property is calculated) the amount of over excavation needed for an economical design. It would be nice to have the calculations to go along with a "hunch". Thanks in advance ...
