Built for Velda City's ground
Upland soils across St. Louis County are mostly loess, and the county soil survey warns that local roads and streets on them need enough base material plus side ditches and culverts, because low strength and frost action cause the damage. We work the same way on drives: drainage, compacted rock, then asphalt.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.
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 Velda City estimate is sized to the soil, the traffic and the drainage on your property.
