Built for Scotsdale's ground
Slopes over 20 percent are common in this part of Jefferson County, so water gets moving before it has anywhere to go. Cherty red clay over limestone drains unevenly, and freeze-thaw winters work whatever stayed wet into the cracks. Culverts, ditches and a properly compacted base are the whole defense.
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 Scotsdale estimate is sized to the soil, the traffic and the drainage on your property.
