Cost of Tar-and-Chip vs. Other Driveway Types
Tar-and-chip driveways are one of the most budget-friendly driveway options. They typically cost $1-3 per square foot installed. This compares to:
- Asphalt driveways: $3-6 per square foot
- Concrete driveways: $5-10 per square foot
- Paver driveways: $10-20 per square foot
So tar-and-chip is generally 50-75% cheaper than other popular driveway materials. The low cost makes it an attractive choice for homeowners on a tight budget.
Durability and Lifespan
With proper care and maintenance, a tar-and-chip driveway can last 10-15 years or more. That’s comparable to asphalt in terms of lifespan. Here’s how it stacks up:
- Tar-and-chip: 10-15 years
- Asphalt: 10-20 years
- Concrete: 20+ years
- Pavers: 20-25 years
Tar-and-chip won’t last as long as concrete or pavers, but it has a longer lifespan than some homeowners realize when properly maintained. Restoring the top layer every few years will extend its durability.
Appearance
Tar-and-chip driveways have a distinctive, gravelly look thanks to the aggregate stones used in the process. The finish has a rougher texture than smooth asphalt or concrete. Some homeowners find the appearance charming and rustic. Others prefer the more refined look of other materials. It’s a matter of personal taste.
Traction and Skid Resistance
The aggregate stones in tar-and-chip provide excellent traction, even in wet conditions. The rougher texture gives tires something to grip compared to smooth concrete or asphalt. This makes tar-and-chip a good choice for driveways in cold climates where snow and ice are a concern.
Maintenance Requirements
Tar-and-chip driveways require periodic maintenance as the top layer of aggregate wears down over time. Restoring the surface with a fresh layer of tar and chips every 3-5 years will extend the driveway’s life. This recoating process is inexpensive compared to replacing the entire driveway.
Beyond recoating, tar-and-chip driveways have minimal maintenance needs if the underlying base was properly prepared. Sweeping loose rocks and keeping drainage pathways clear prevents faster deterioration of the surface.
Climate Considerations
Extremely hot climates can be a challenge for tar-and-chip driveways. The sun’s heat can soften the asphalt tar over time, causing the aggregate to dislodge more easily. But periodic recoating will keep the driveway intact even in hot southern states. Cold climates are not an issue.
Environmental Impact
Tar-and-chip driveways have the advantage of being 100% recyclable. The aggregate stone and sand can be reused repeatedly. And existing tar can be reclaimed when recoating, minimizing waste. So tar-and-chip is among the most eco-friendly driveway options.
FAQs
How long do tar-and-chip driveways usually last?
With proper maintenance like periodic recoating, a tar-and-chip driveway can last 10-15 years or longer. The lifespan varies based on climate, usage levels, and quality of the original installation.
How do you repair a tar-and-chip driveway?
Basic repairs include sweeping loose aggregate, patching isolated cracks/holes with asphalt patch compound, and applying a new top layer of tar and chips across high-traffic areas or where the current layer is worn.
Does tar-and-chip look like gravel?
Tar-and-chip does have a loose gravel appearance thanks to the aggregate stone used. The stones provide excellent traction. Some homeowners choose tar-and-chip specifically for the distinctive gravelly look.
Is tar-and-chip slippery in winter?
Tar-and-chip provides great traction, even in winter weather, due to the rough texture of the aggregate stone. It’s less prone to being slippery compared to smooth asphalt or concrete.
Can you plow snow on tar-and-chip driveways?
Yes, you can plow snow on tar-and-chip driveways. The key is using a plow blade suitable for gravel surfaces to avoid catching on the stones. Make sure to keep plowing speed slow to minimize possible damage.
Does tar-and-chip track into garages like gravel?
Tar-and-chip resists tracking and spreading of loose aggregate better than pure gravel. But some stones may still get picked up by tires and tracked inside. A stone driveway apron can help minimize the issue.
Conclusion
For homeowners wanting an affordable and durable driveway material, tar-and-chip deserves strong consideration. Its lower upfront cost and simple maintenance make it budget-friendly long-term compared to concrete or pavers. Just be prepared for its distinctive gravelly appearance and periodic need for recoating. With realistic expectations, tar-and-chip can be an ideal choice to freshen up a worn asphalt or concrete driveway on a budget.
