Built for Bismarck's ground
St. Francois County soils run to clay over dolomite on the Farmington Plain and red cherty clay in the dissected hills, and the NRCS notes low strength for vehicle traffic on several of them can be corrected with suitable base material. That is the job here: dig out the weak layer, replace it with compacted rock, then pave.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.
Compacted asphaltTypically 2 to 3 in. for a car drive
Stone baseTypically 4 to 8 in., compacted
Drive on itUsually 2 to 3 days, longer in heat
First sealcoatTypically 6 to 12 months after paving
Typical ranges. Your Bismarck estimate is sized to the soil, the traffic and the drainage on your property.
