Key takeaways
- Long Valley driveways are often long, steep and rocky, so they need a heavier base and careful compaction.
- Runoff control (crowning, swales, culverts, trench drains) protects the asphalt.
- Belgian block edging stops edges from washing out on slopes.
- A well-built blacktop driveway lasts 15–25 years with maintenance.
Blacktop is a natural fit for Long Valley’s long driveways. It’s cost-effective over large areas, handles plowing and salt, and is easy to maintain. But Long Valley’s terrain, especially on Schooley’s Mountain, demands extra care.
Challenges of Long Valley driveways
- Steep grades that make compaction harder and increase runoff
- Rock ledge close to the surface
- Long distances that multiply the impact of every design decision
- Heavy runoff in storms that can wash out edges and undermine the base
How we handle them
- Grade and crown the driveway so water sheds to the sides
- Add swales, culverts or trench drains where water crosses or collects
- Use a heavier stone base, compacted in lifts
- Pave in controlled passes on grades for consistent density
- Protect edges with Belgian block where runoff is strong
Aftercare
Avoid turning the wheel while parked on fresh asphalt, keep heavy trucks off for a few weeks, and sealcoat after 6–12 months, then every 2–3 years.

Troubleshooting: common problems and fixes
Here’s how we diagnose and fix the issues we see most often on projects like this.
Steep drives on Schooley’s Mountain
What you see: Washed-out edges, slick winter surfaces and runoff damage.
Why it happens: Steep grades and heavy runoff.
How we fix it: Heavier base, crowned surfaces, swales, culverts and Belgian block edges.
How to prevent it: Clear drainage each season.
Rock and boulders during excavation
What you see: Ledge and large stones when digging.
Why it happens: Rocky glacial terrain.
How we fix it: Proper equipment and design adjustments, priced transparently.
How to prevent it: Expect it and plan for it.
Ruts and sunken tire tracks
What you see: Two depressions where the car always parks or drives, sometimes holding water.
Why it happens: Too thin a base, poor compaction, or heavy vehicles (work trucks, RVs, dumpsters) on a driveway designed for cars.
How we fix it: Ruts mean the base deformed. Small areas are excavated and rebuilt. Widespread rutting calls for replacement with a thicker base and asphalt section sized for the heavier vehicles.
How to prevent it: Tell your contractor about any heavy vehicles before paving, and use plywood under dumpster wheels and trailer jacks.
Plows keep tearing up the edges
What you see: Chunks of asphalt are pushed onto the lawn every winter, and the edges get rougher each year.
Why it happens: Unsupported asphalt edges, and plow blades set too low.
How we fix it: We rebuild the edges on a wider base and install Belgian block curbing as a solid, plow-resistant border.
How to prevent it: Mark the edges with stakes before winter and ask your plow service to use a shoe or rubber edge.
Alligator (spider-web) cracking
What you see: A patch of interconnected cracks that looks like reptile skin, usually in wheel paths or near the garage.
Why it happens: The base underneath has failed. Water got through surface cracks, softened the stone and soil, and the asphalt is now flexing under every car. It’s a structural failure, not a surface one.
How we fix it: We saw-cut around the failed area, dig out the asphalt and the wet base, install and compact new stone, then patch with hot-mix asphalt. If more than about a quarter of the driveway looks like this, full replacement is the better value.
How to prevent it: Seal cracks as soon as they appear, keep downspouts discharging away from the driveway, and sealcoat every 2–3 years.
What affects the cost
- Size and shape: square footage, curves and the number of cuts and transitions
- Removal: tearing out and disposing of old asphalt or concrete
- Base work: how much excavation and new stone is needed, which depends on soil and existing conditions
- Asphalt thickness and mix: heavier sections for long lanes, trucks and commercial use
- Drainage: trench drains, dry wells, swales or regrading
- Access and slope: steep or tight sites take more time and smaller equipment
- Edging and extras: Belgian block curbing, aprons, parking pads
Mistakes to avoid
- Hiring a door-to-door “leftover asphalt” crew
- Accepting a quote that doesn’t state base depth and compacted asphalt thickness
- Paving over a failed base and expecting the cracks not to return
- Sealcoating brand-new asphalt too early (wait 6–12 months)
- Turning the steering wheel while parked on fresh asphalt in hot weather
- Ignoring small cracks until winter turns them into potholes
Seasonal care checklist
- Spring: Walk the driveway after the thaw. Note new cracks, potholes and puddles, and rinse off winter salt.
- Summer: Best time for crack sealing, patching and sealcoating (dry days above 50°F).
- Fall: Last chance for hot-mix repairs before the plants close. Clean out drains and gutters.
- Winter: Use a plow shoe or rubber edge, avoid metal shovel edges, and use calcium chloride sparingly.
Frequently asked questions
Is asphalt good for steep driveways?
Yes, when it’s compacted properly and drainage is controlled. Asphalt also provides good traction in winter.
Can you pave a gravel driveway in Long Valley?
Yes. We regrade, add and compact base stone over the existing gravel where suitable, then pave.
Why does my asphalt driveway keep cracking?
Most recurring cracks come from water getting into the base, not from the asphalt itself. Seal cracks while they’re small, fix drainage, and if alligator cracking has spread, rebuild the base in that area.
Is cold patch a permanent pothole fix?
No. Bagged cold patch is a temporary fix. A permanent repair is saw-cut, excavated, rebuilt with compacted stone and filled with hot-mix asphalt.
Should I sealcoat every year?
No. Every 2–3 years is right for most driveways. Sealing too often builds up a film that can crack and peel.
