Why the base matters in Pine Lawn
Upland ground across this part of the county is loess over clay, and the county soil survey calls out low strength and frost action for local roads, recommending adequate base material plus side ditches and culverts. Put plainly: water under pavement through a freeze-thaw winter is the enemy. The base and the drainage keep it out.
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.
