Ground, water and winter in Maplewood
I-44 passes just south of the city limits near Deer Creek, and low ground in that direction stays wetter. County upland soils formed largely in loess, and the soil survey says local streets on many of them need adequate base plus ditches and culverts for low strength and frost action. We fix drainage before laying anything.
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 Maplewood estimate is sized to the soil, the traffic and the drainage on your property.
