Key takeaways
- Repair small cracks, isolated potholes and faded surfaces with crack sealing, patching and sealcoat.
- Resurface (overlay) a sound driveway that’s worn on top.
- Replace when there’s alligator cracking, sinking or standing water.
- Keansburg’s salt air, sandy soil and flood risk make drainage and maintenance especially important.
Keansburg driveways face a tougher environment than most: salt air off Raritan Bay, sandy soils, a high water table and the lasting effects of coastal storms. Here’s how to decide whether your asphalt driveway needs a repair, a resurface or a full replacement.
When repair is enough
- Cracks under about 1/2 inch wide
- A few small potholes
- Gray, faded, oxidized asphalt
- Minor edge crumbling
Fix: clean and seal cracks with hot-pour sealant, cut out and patch potholes with hot-mix asphalt, then sealcoat. See repairs and sealcoating.
When resurfacing makes sense
If the driveway is structurally sound (no sinking, good drainage) but the surface is rough or heavily weathered, a 1.5–2 inch asphalt overlay can renew it. See paving over old asphalt.
When to replace
- Interconnected “alligator” cracking
- Sunken areas or ruts
- Standing water or water flowing toward the house
- Repeated patches that keep failing
These signal a failed base. Only full replacement with a new compacted base will last.
Keansburg-specific tips
- Pitch the driveway so water drains quickly to the street
- Sealcoat every 2–3 years to protect against salt and UV
- Rinse salt off in spring
- Rebuild edges with Belgian block where they crumble

Troubleshooting: common problems and fixes
Here’s how we diagnose and fix the issues we see most often on projects like this.
Homes raised after Hurricane Sandy needing new stairs
What you see: Raised homes with temporary or failing steps and landings.
Why it happens: Elevation changes after flood mitigation.
How we fix it: New masonry or paver stairs and landings with safe, consistent risers and proper footings.
How to prevent it: Choose materials that tolerate salt and flooding.
Sandy soils and high water table
What you see: Pavers and driveways settling or shifting.
Why it happens: Loose sandy soils that drain fast but compact poorly when wet.
How we fix it: Well-graded, compacted base and edge restraints designed for sandy conditions.
How to prevent it: Maintain edges and joints.
Gray, faded, dried-out surface
What you see: The driveway has turned light gray, the stones are showing, and it feels rough underfoot.
Why it happens: Sun (UV), water and road salt oxidize the asphalt binder over time, making the surface brittle and porous.
How we fix it: If the surface is structurally sound, we fill cracks and sealcoat to restore color and protection. If the stone is coming loose (raveling), a 1.5–2″ overlay renews the surface.
How to prevent it: Sealcoat every 2–3 years starting 6–12 months after paving, and don’t over-seal yearly, which can cause peeling.
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.
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
Does salt air damage asphalt?
Salt and UV speed up oxidation and drying of asphalt. Regular sealcoating helps protect it.
How long does an asphalt repair last?
Properly cut and hot-mix patched repairs can last many years when the surrounding base is sound.
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.
