Asphalt Driveway Types for St. George Homes
New-construction driveways on bare lots
On a new lot nothing is there yet, so most of the work happens before any asphalt shows up: clearing, cutting to grade, then building and compacting the base. That prep is where cheap bids cut corners. Angi adds $5 to $10 per sq ft for grading and leveling where the ground needs it, and HomeGuide says clay soils often need extra digging and base to stop cracking and settling later. The local soil picture is on the grading and base preparation page, and any digging in the street at the driveway mouth falls under the city permit covered on driveway extensions.
- Base: 6 to 8 inches of compacted gravel
- Asphalt: 2 to 3 inches compacted
- Grading where needed: $5 to $10 per sq ft on top of paving
Two- and three-car driveways
Size moves the price more than anything else. Angi puts most home driveways between 200 and 800 sq ft, depending on whether they serve one car or two, and a three-car garage front sits at or past the top of that band. National ranges by size:
- 200 sq ft: $1,400 to $2,600
- 20 x 20 ft (400 sq ft): $2,000 to $4,800
- 500 sq ft: $2,500 to $6,000
- 800 sq ft: $5,600 to $10,400
Measure the full width at the garage doors as well as the length: a third bay or a side-loading turn adds square footage that a quick length-times-two-cars guess misses.
Sloped and hillside driveways
A driveway that climbs to the garage takes more prep, and HomeGuide says curves, slopes and odd shapes add 15% to 30% to the price. Angi advises talking through a steep site with a paving pro before you settle on a budget. Water follows the slope, so the question to ask is where runoff goes before it reaches the garage slab. Driveway drainage covers the fixes, from swales to catch basins.
Circular and turnaround driveways
A loop or a backing-out turnaround saves you reversing into the street, but Angi lists circular layouts and long runs from road to garage among the things that raise square footage and cost. The curves themselves fall under HomeGuide's 15% to 30% premium. Ask each contractor for a sketch with the measured square footage, so you're comparing bids for the same shape.
Heavy-duty driveways for trucks and trailers
A work truck, boat or travel trailer is a heavier load than a car driveway is built for. HomeGuide specifies a deeper section for heavy vehicles and prices reinforcement as an add-on.
- Asphalt: 3 to 4 inches compacted (4 inches or more where heavy vehicles are routine)
- Base: 8 to 10 inches compacted
- Reinforcement add-on: $500 to $2,000
- Heavy vehicles off the new surface: at least a week
A dedicated pad for a motorhome or fifth wheel is its own job; see RV pad paving.
Why St. George homeowners and property managers call St. George Asphalt Co.
- The estimate costs you nothing and commits you to nothing
- Ask for thickness, base depth and tear-out on the written bid
- Your job goes to one paving contractor, never a lead auction
- Property owners pay nothing for the introduction
Asphalt Driveway Cost: What Changes the Bid
National cost guides frame these numbers. They aren't any contractor's price list. HomeGuide splits its $5 to $12 per sq ft into roughly $3 to $6 for labor and $2 to $6 for materials; Angi's figure for a new driveway is $7 to $13. From there the price moves with a few things you can check on your own lot:
Square footage
Length times width, plus any turnaround, flare or parking spot.Base work
Grading, hauling off soft soil and adding road base all happen before paving, and they cost more on clay.Shape and slope
Curves, slopes and unusual outlines add 15% to 30%.Job minimum
Some contractors won't move equipment for less than about $2,000.Season
HomeGuide says spring through early fall is peak season and a winter job may save 10% to 15%. Ask whether a winter date changes the bid here.
Asphalt Driveway Thickness, Base and Cure in St. George Heat
Summer is hard on fresh asphalt here. In the Western Regional Climate Center's long-term St. George record, July afternoons average 101.6°F and roughly 124 days a year top 90°F. HomeGuide's normal wait before driving is 24 to 48 hours, but it stretches that to 3 to 5 days in hot weather, and St. George's average highs run from 96.1°F in June to 99.5°F in August on top of July's peak. Fixr adds that for the first few weeks you should avoid parking on it during very hot days, because heat can soften the surface. A driveway finished in early summer has more of those days ahead of it than one finished in October.
Before you sign, these are the questions that show whether a bid will hold up:
Compacted thickness
Ask for both asphalt and base depth after compaction, written on the bid.Base material and compaction
Ask what goes under the asphalt and what compacts it. A good paving contractor will proof-roll the base before paving.Drainage
Ask how the finished surface will shed water away from the garage and the house.Edges
Ask how the edges will be finished and backfilled. Fixr's upkeep advice is to check driveway edges often for crumbling.First seal
New asphalt shouldn't be sealed straight away; sealcoating explains when.
