Size, and specifically shape
Square footage is the starting point, but shape matters nearly as much. A long straight run is efficient to pave. The same square footage split into a narrow drive, a turnaround and a pad means more hand work, more edges and more time.
What is under the surface right now
This is the biggest single variable and the one homeowners are most often surprised by. If there is a sound base under an old drive, the job is much simpler. If the base was never properly built, or it has been contaminated over the years, that material has to come out and be rebuilt before anything gets paved.
This is also why a walk-through matters. The old surface tells us a lot, and so does how the ground behaves after rain.
Grade and drainage
If water currently runs toward your garage or stands somewhere on the drive, correcting that is part of the job. Regrading costs money in the estimate and saves considerably more than it costs, because water is what destroys pavement.
Asphalt thickness
Thickness is specified for the traffic the surface will carry. A passenger vehicle driveway does not need the section a delivery route needs. Paying for thickness you do not need is waste, and going thin on a drive that sees heavy vehicles is a false saving.
Access and working room
Equipment has to reach the work. Tight gates, overhead limbs, narrow side yards, soft ground and long hauls from where trucks can park all add time. Mature oak canopy, which is most of this area, is a common factor.
Edges, aprons and tie-ins
Where the drive meets the road, the garage slab, a walkway or existing concrete, the detail work takes time and it is what you look at every day. More tie-ins means more of that work.
Removal and disposal
If an existing surface has to come out, removal and haul off is part of the cost. Sometimes milling the existing asphalt is the better route, and the material may be reusable.
Questions worth asking any contractor
- What asphalt thickness is in this price, and why that thickness?
- Does the price include base work, or does it assume the existing base is fine?
- What happens to the price if you find bad base once you start?
- How is drainage being handled?
- Is removal and disposal included?
- Is the estimate in writing, with the scope described?
