how do you design a dirt road to prevent erosion for heavy duty transport equipment carrying tons of ore 50 times a day, in and out, back and forth? What specifically can be done to prevent dirt road erosion and dirt mush? Do you actually pave miles of road in a steeply inclined road? How long does it last, and what is the cost?
FWIW, the processing plant IS enclosed, but the approaching grounds getting to the enclosure is not, or you build a structure miles long covering the roaad for miles. Of course that doesn't make sense.
