A new asphalt driveway goes in over eight steps: site visit and plan, clearing and excavation, grading for drainage, building and compacting the base, a proof roll, paving, rolling, and curing. Most of the work, and most of what makes a driveway last, happens below the surface. It starts with what happens during estimates. Questions? Call (210) 326-5707.

In this article: the eight installation steps, what goes under the asphalt, how Hill Country soil changes the plan, a day-by-day timeline, when you can drive and park, and common questions.
Key Takeaways
- The base is the driveway. Six to eight inches of compacted stone base under the asphalt is a common residential standard.
- Drainage is designed in, not added later. Grading for slope happens before any asphalt arrives.
- Compaction decides lifespan. Each extra 1 percent of density adds roughly 10 percent to service life.
- Hill Country ground needs local judgment. Limestone, caliche and swelling clay each call for a different base plan.
- Patience after paving pays off. Wait a few days to drive on it and several months before sealcoating.
The 8 Steps of New Driveway Installation
Here is the full process for a new asphalt driveway, from the first visit to the first drive. Each step builds on the one before it.
- Site visit and plan. The contractor measures, checks soil and drainage, and agrees on layout, thickness and base depth in a written estimate.
- Clearing and excavation. Grass, topsoil, roots and any old surface come out. Soft or organic soil is dug down to firm ground.
- Grading for drainage. The subgrade is shaped so water runs off, usually with a crown or cross slope.
- Base placement and compaction. Crushed stone base goes down in layers, and each layer is compacted with a roller.
- Proof roll. A loaded truck or roller drives over the base. Any spot that flexes or pumps gets dug out and fixed.
- Paving. Hot mix asphalt is placed with a paver, often in a binder layer and a surface layer.
- Rolling and finishing. Rollers compact the hot asphalt while it is still workable. Edges, seams and transitions are finished.
- Curing and first use. The surface cools and hardens. Traffic stays off until it is ready.

What Goes Under a New Asphalt Driveway?
A new driveway is a layered system. The Colorado Asphalt Pavement Association’s best practices call for 6 to 8 inches of crushed aggregate base, topped with about 2 inches of bottom asphalt and 1.5 inches of surface asphalt. The subgrade underneath should be free of organic material, with weak spots removed and replaced.
| Layer | Typical residential spec | Job |
|---|---|---|
| Surface asphalt | About 1.5 inches | Smooth, sealed driving surface |
| Binder asphalt | About 2 inches | Carries the load |
| Crushed stone base | 6 to 8 inches, compacted | Spreads weight and drains water |
| Subgrade | Firm native soil, graded and compacted | Foundation for everything above |
Some driveways use a single 2 to 3 inch asphalt layer instead of two, depending on traffic and budget. Our guide to the right asphalt thickness covers which option fits cars, trucks and RVs.
Why Compaction Matters So Much
Well-compacted asphalt resists water, ruts and cracking. Asphalt Institute research puts normal field targets at 92 to 93 percent density, and it links each extra 1 percent of density to roughly 10 percent more service life. That is why rolling happens fast, while the mix is still hot.
How Does Hill Country Soil Change the Process?
Hill Country ground is not one soil. The Texas Almanac describes Edwards Plateau uplands as mostly shallow, stony clays over limestone, while the Blackland Prairie to the east has cracking clays that swell and shrink. Here is how that changes a new driveway.
Shallow Limestone
Rock can sit just inches down. That makes a strong foundation, but excavation may mean breaking or trimming rock, and drainage has to be planned so water does not sit on top of it.
Caliche
Caliche is a hard, chalky layer common in the region. It can make a firm subgrade when it is solid and dry. Loose or broken caliche needs to be compacted or replaced so it does not soften when wet.
Expansive Clay
Clay pockets move with moisture. Soft clay gets dug out and replaced with base, and the base is built thicker. The Texas Asphalt Pavement Association notes that lime treatment of clays is common in Texas to limit swelling on larger projects.
Site prep on tough ground is its own trade. Our site grading and excavation work handles rock, caliche and clay before paving starts.

New Driveway Timeline: What to Expect Day by Day
Every job is different, but most residential driveways follow a similar rhythm once work starts.
| Stage | Typical timing | What you do |
|---|---|---|
| Excavation and grading | Day 1 | Move vehicles out, keep kids and pets clear |
| Base placement and compaction | Day 1 to 2 | Stay off the base; it is being tested |
| Paving and rolling | Day 2 or 3 | Watch from a distance; crews move fast |
| Walk on it | After it has cooled | Light foot traffic only |
| Drive on it | After a few days | Drive slowly, no sharp turns |
| Heavy vehicles and trailers | After the first few weeks | Use boards under jacks and kickstands |
| First sealcoat | After several months | Let the asphalt cure fully first |
In a Texas summer, fresh asphalt stays soft longer. Plan on extra care during the first hot weeks.
How to Care for a New Asphalt Driveway
- Keep traffic off until your contractor says it is ready.
- Avoid turning the wheel while parked, especially on hot afternoons.
- Park in different spots so one area does not rut.
- Protect the edges. Edges are the weakest part, so do not drive off them.
- Hold off on sealcoat for several months.
- Keep drains clear so water does not sit along the sides.
New Driveway Installation Questions We Hear Most
What are the steps involved in installing an asphalt driveway?
The steps are: site visit and plan, clearing and excavation, grading for drainage, placing and compacting the base, a proof roll, paving, rolling, and curing. The base and drainage steps matter most for how long the driveway lasts.
What do you put down before asphalt?
A compacted crushed stone base goes down before asphalt, often 6 to 8 inches deep on a residential driveway. It sits on graded, compacted native soil. Soft spots and organic soil are removed first.
How many days before driving on a new asphalt driveway?
Plan on a few days before driving on it, and longer in hot weather. Keep heavy trucks, trailers and RVs off for the first few weeks, and follow your contractor’s timing.
What not to do on a new asphalt driveway?
Do not turn your wheels while parked, park heavy vehicles in one spot, drive on the edges, or put jacks and kickstands directly on the surface. Do not sealcoat it in the first several months.
How long does new driveway installation take?
Most residential driveways take one to three days of work once the crew starts. Removal of an old surface, rock work or extra base can add time. Weather can also shift the schedule.
