Ground, water and winter in Carlinville
Clay-heavy soils common across the region drain slowly once wet, and water sitting under pavement is what freeze-thaw winters turn into cracks and heaves. We set the grade so runoff leaves the surface, dig out soft subgrade and compact clean rock in layers. Drainage comes first, because asphalt over wet ground fails early no matter how thick it goes.
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.

Typical ranges. Your Carlinville estimate is sized to the soil, the traffic and the drainage on your property.
