Ground, water and winter in Iron Mountain Lake
St. Francois County soils include clayey material over dolomite and loamy material over sandstone, and the NRCS notes low strength for vehicle traffic that suitable base material corrects. Near water, low ground stays saturated after storms. A wet base plus freeze-thaw winters is what breaks asphalt apart.
The part of the job you can see is the last two inches. Ask what is underneath, how it will be compacted, and which way the finished surface drains.
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 Iron Mountain Lake estimate is sized to the soil, the traffic and the drainage on your property.
