New asphalt paving means building a pavement section from scratch, either on ground that's never been paved or on an old surface that's failed badly enough that patching it is just delaying the inevitable. It's the most involved paving job there is, and also the one that lasts longest when it's done right, because everything from the compacted base up gets built to handle whatever's going to drive, park, or sit on it for the next fifteen to twenty years. This page covers both versions: paving somewhere for the first time, and rebuilding a section that's failed too badly for a patch or an overlay to help.
Anywhere there's currently no asphalt at all. A dirt or gravel driveway getting paved for the first time, a new HOA common area or guest lot being built as part of a development, a commercial pad that's been sitting as compacted decomposed granite since the building went up. New construction paving starts with an engineered base instead of inheriting whatever's already there, which is actually the easier version of this job. There's no old pavement to remove, no guessing about what's hiding underneath, just a clean grade to build on.
Full-depth reconstruction is what happens when existing pavement has failed past the point an overlay or a patch can fix. The old asphalt and the base underneath it both get removed, the subgrade gets inspected and re-compacted, sometimes with soil stabilization if it's saturated or unstable, and the whole structure gets rebuilt from native ground up. It's more expensive than an overlay and takes longer, but it's the only real fix for a lot or driveway where the base has failed across most of the surface rather than in one or two spots. Alligator cracking spread across sixty or seventy percent of a driveway is usually the signal that reconstruction, not another patch, is the honest answer.
Two, typically, sitting on top of a compacted aggregate base. Most residential work uses a single asphalt lift, generally in the range of two to three inches, over four to six inches of compacted base rock. Heavier-use surfaces, an HOA drive aisle or a commercial lot that sees delivery trucks and trash trucks, often get a two-lift asphalt section instead: a binder course for structural strength, then a thinner surface course on top for the finish everyone actually drives on. The base rock matters as much as the asphalt itself. Skimp on base thickness or compaction and it doesn't matter how much asphalt goes on top, the pavement will rut and crack early because it's flexing on a foundation that can't support it.
Because a well-compacted base is what keeps the pavement from moving once it's built, and asphalt on the move is asphalt that cracks. This matters more in the South Bay than it does on flat ground elsewhere, since a lot of new paving here happens on graded hillside lots or fill soil brought in during development. Fill soil that isn't compacted to spec settles unevenly over time, and a pavement section built on top of it inherits that unevenness as cracking and low spots, sometimes a year or two after the job looked perfect on the day it was finished. A contractor doing this correctly tests compaction as the job goes, not just at the end.
Sometimes, yes. Standard hot-mix asphalt works fine for most residential driveways, but for lots and drive aisles that sit in direct sun all day with heavy or slow-turning traffic, some contractors spec a polymer-modified binder, an asphalt mix with additives that improve resistance to rutting and softening in high heat. It costs more than standard mix and isn't necessary for every job. A shaded residential driveway rarely needs it. A south-facing HOA lot that bakes all afternoon and sees trash trucks pivoting in the same two spots every week is exactly the kind of job where the upgrade earns its cost back.
Before a base rock ever gets delivered, a contractor should walk the site and figure out where water needs to go, because paving locks in whatever grading decisions get made at this stage for years. On a flat lot, that mostly means a gentle slope toward a drain or the street. On a hillside property, and eastern Chula Vista has plenty of those, it means more careful planning: cross-slopes to prevent sheet flow from running straight down a long driveway, and sometimes a swale or drain inlet partway down to catch water before it reaches the garage or the street below. Getting this step wrong is one of the more common reasons a new paving job develops problems within a year or two, and it has nothing to do with the asphalt itself.

For a driveway, often two to four days: excavation and base prep take longer than the actual asphalt paving, which can go down in a matter of hours once the base is ready. A larger lot stretches that timeline out over a week or more, partly because of size and partly because compaction testing and inspection between phases take real time, not because anyone's working slowly. Asphalt itself cools enough to walk on within a few hours but needs a few days before it's ready for regular vehicle traffic, longer in cooler weather. Permit review and utility locates can also add time before the crew ever shows up, especially on a first-time paving job where the city wants to confirm drainage before an impervious surface goes in.
More than an overlay, more than a repair, and a lot more than sealcoating, because it's the only one of the four that includes rebuilding the structure underneath the surface. That's not a reason to avoid it when it's actually needed. A full-depth job done once, on a properly compacted base, tends to outlast years of patch-and-hope work on a section that never should have been patched in the first place. The paving cost page breaks down the logic in more detail, including why a small driveway sometimes costs more per square foot than a large lot does.
If the cracking is widespread, if you can see movement or dips across most of the surface, or if a previous overlay already failed, the base underneath is likely compromised. An overlay only works when the base is still sound. A contractor can usually tell within a short site visit, sometimes with a core sample if it's not obvious.
Not directly. Gravel makes a reasonable start for a base but almost never has the compaction or grading a paved surface needs. Expect the existing gravel to get regraded and compacted, sometimes with additional base rock added, before asphalt goes down on top of it.
Usually, especially if the work touches the sidewalk apron or the public right-of-way. Your contractor should handle pulling the permit as part of the job, but it's worth confirming that upfront rather than assuming it's included.
Most contractors ask for a few days before regular vehicle traffic, sometimes longer in cooler or damp weather. Walking on it sooner is generally fine once it's cooled, but heavy or turning loads too early can leave marks in asphalt that hasn't fully firmed up.
The binder course is the lower, coarser asphalt layer that provides most of the structural strength. The surface course is the thinner, finer layer on top that gives the smooth finish you actually see and drive on. Light-duty driveways often skip the binder course and use a single lift; heavier-use surfaces usually get both.
