Why the base matters in Hazelwood
Cowmire Creek runs through the city to the Missouri River, and the low ground near it drains slowly. Upland soils formed in loess, and the county soil survey flags low strength and frost action for local roads, correctable with adequate base and drainage. We grade for runoff first, then build the base in layers.
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 Hazelwood estimate is sized to the soil, the traffic and the drainage on your property.
