Why the base matters in Edmundson
Airport-area ground is flat, which means water leaves slowly unless the pavement is graded to move it. St. Louis County loess uplands need enough base material plus ditches and culverts to resist low strength and frost action, according to the county soil survey. We compact rock in layers and set a grade that drains.
Before you sign anything, get the base depth and the compacted asphalt thickness on paper. Two bids that look far apart are often just two different pavements.
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 Edmundson estimate is sized to the soil, the traffic and the drainage on your property.
