Why the base matters in Troy
Most of the city drains east to Silver Creek tributaries, while the west side runs toward Canteen Creek and the river valley. Upland soil here is thick windblown loess silt that holds moisture, and freeze-thaw winters lift pavement resting on a wet base. We strip soft material, compact rock in lifts and grade for runoff.
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 Troy estimate is sized to the soil, the traffic and the drainage on your property.
