Built for Albers's ground
This is flat to gently rolling farm country, and flat ground gives water nowhere to run on its own. Slow-draining silty soils are common through this part of Illinois, and freeze-thaw winters lift whatever sits on a wet base. We set the grade first, pull weak material, and compact rock in lifts before paving.
When you compare bids, ask each contractor for three numbers in writing: the compacted asphalt thickness, the base depth, and what happens to the water. Those three decide how long the surface lasts.
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 Albers estimate is sized to the soil, the traffic and the drainage on your property.
