Tar and Chip Driveway and Chip Seal Installation
Tar and chip, also called chip seal, is the right answer for long rural driveways, private roads, and properties where the suburban asphalt look feels wrong. We spray hot liquid asphalt, then embed angular stone chips into the surface while it's still hot. The result is a durable, textured driveway that handles freeze-thaw better than gravel and looks at home on a farm or wooded lot.
The economics work for long drives: at 800 feet or more, tar and chip can come in 20 to 35 percent cheaper per square foot than full asphalt. And there's no sealcoating to schedule, the chip surface is the wear layer.
We install tar and chip driveways across Warren, Sussex, Hunterdon counties NJ and Northampton, Lehigh, Bucks counties PA. Most of our tar and chip jobs are 500 feet or longer.
Tar and chip cost vs asphalt
Tar and chip is priced per square foot with stone color and base condition driving most of the variance. The savings vs hot-mix asphalt grow with length.
- Base inspection + prep (By base condition): Existing base graded and compacted. Long drives often need spot fill before chip seal.
- Hot liquid asphalt (By square foot): Sprayed evenly at temp. Coverage varies with surface porosity.
- Stone chips (color of choice) (By the load): Angular stone, gray/tan/brown/red. Trucked in by load.
- Roll-in + cure (By crew time): Heavy roller embeds the chips into the hot asphalt.
Tar and chip materials
Two materials and a roller. The simplicity is part of why this surface is so durable on rural drives.
- Liquid asphalt (binder): Hot-applied asphalt emulsion sprayed evenly across the prepared base. The 'tar' in tar and chip, though technically modern formulations are asphalt-based, not coal tar.
- Stone chips: Angular crushed stone in your chosen color. Angular (not round) so they lock into each other and into the asphalt.
- Compaction: Pneumatic roller passes embed the chips into the hot asphalt while it's still tacky. Timing matters, this is the part where experience shows.
Why tar and chip works in NJ + PA rural areas
Sussex, Warren, and Hunterdon counties in NJ have a lot of properties on long lots: 500 to 2,000 ft driveways are common. At those lengths the 20 to 35 percent difference between asphalt and tar and chip stops being a rounding error and starts being the deciding factor.
Lehigh Valley PA on the Bucks and Northampton side has similar long-drive country properties where chip seal is the dominant choice. The look fits the property style and the maintenance demands are lower.
Freeze-thaw on tar and chip behaves differently than on asphalt. The textured surface flexes and the embedded chips redistribute load. Properly installed chip seal handles NJ winters without the cracking that punishes thin asphalt drives.
Tar & Chip Driveways FAQs
How much does a tar and chip driveway cost in NJ?
Tar and chip typically prices 20 to 35 percent below hot-mix asphalt on the same footprint, and the gap widens the longer the driveway. Exact pricing depends on width, base condition, and the stone color you choose. We measure and quote it in writing.
What stone colors are available?
Standard options are gray, tan, brown, and red. The stone is a permanent part of the surface so the color choice matters for curb appeal. We bring samples to the estimate.
How long does a tar and chip driveway last?
10 to 15 years with proper base, sometimes longer. The chip layer slowly weathers but the underlying tar bond stays. You can refresh with a top-coat at year 7 or 8 to extend it.
Can I plow tar and chip?
Yes, but use a poly or rubber-edge plow, not a metal-edge plow. Metal scrapes chips loose over time. Most rural property owners run a poly edge anyway because it's easier on the truck.
Will I have loose chips for a while?
Yes, for the first 2 to 4 weeks. Sweep up the loose ones and they're done. The bonded chips stay put for the lifespan of the driveway.
Is tar and chip the same as chip seal?
Yes, same thing. 'Chip seal' is the term road departments use, 'tar and chip' is what homeowners search for. We do both, residential and private roads.
Can you put tar and chip over an existing driveway?
If the existing base is sound, yes. We can chip seal over a worn asphalt driveway as a cost-effective refresh, or over a compacted gravel drive that's settled and stable. We won't do it over a failing base, that's just hiding the problem.
