Built for Spanish Lake's ground
Ground near the confluence runs from river bottom to loess upland, and the county soil survey lists low strength and frost action on many upland soils, recommending adequate base material plus ditches and culverts. Low ground near the rivers holds water longer still. Getting runoff off the surface and out of the base is the work that lasts.
A cheap bid usually gets cheap somewhere you cannot see. Ask what depth of stone goes down, how thick the asphalt is after rolling, and who fixes it if water still stands.
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 Spanish Lake estimate is sized to the soil, the traffic and the drainage on your property.
