One of its greatest advantages is its ease of maintenance – unlike some surfaces that require regular sealing, tar and chip can be quickly repaired with crushed stones as small cracks appear, especially during hot seasons when the material tends to heat up and ‘melt’ slightly.
This low-maintenance design also contributes to its impressive durability, lasting up to 12 years without the need for additional layering or sealing. In fact, this cost-efficiency is a major draw for many homeowners. Another key benefit of tar and chip driveways is their excellent traction – similar to asphalt, they provide a smooth, bump-free surface for cars to glide across.
And with its natural earthy tone, achieved through the combination of tar-like substance and crushed stones in various colors, you can enjoy a beautiful, rustic aesthetic that complements your home’s surroundings.
Cons
While tar and chip driveways don’t succumb to heat, they do have one Achilles’ heel – snow plows. In areas where thick layers of snow are a regular occurrence, this material might not be the best choice. If you’re considering a tar and chip driveway in such a location, it’s essential to weigh the pros and cons carefully. On the other hand, if you’re handy with a trowel, mastering the installation process can be a cost-effective way to go about it.
However, be aware that there is a dearth of experienced tar and chip contractors, making DIY installation more challenging than usual. Another consideration is the long-term maintenance of a tar and chip driveway. As the crushed stones break down over time, they can create a messy situation if left unattended. To maintain the integrity of your driveway, it’s recommended to rejuvenate the top layer at least once a year to ensure the stones remain intact.
Tar and chip driveway installation
While tar and chip installation shares some similarities with asphalt concrete installation, there are distinct steps involved. To give you a comprehensive overview of the process, we’ll break down the key stages for your reference. Start by laying down the gravel base according to the desired dimensions of your driveway. Next, melt the liquid asphalt and pour it over the gravel base. At this point, you can choose the color of crushed stones you’d like to use as the topping.
Spread the chosen stones evenly over the liquid asphalt. To complete the surface, apply a thin layer of bitumen and roll it to ensure even coverage. Allow the tar and chip driveway to cure for several days or up to a week before using it. If you’re considering installing your tar and chip driveway DIY-style, there are some essential installation tips to keep in mind. Firstly, it’s crucial to install during warmer seasons when the molten liquid asphalt can dry and cure properly.
The surface should be well-prepared by removing any obstructions – from small leaves to larger structures like basketball rings. Power washing the surface is also necessary to remove any debris or impurities. Additionally, fixing cracks, holes, and dents is vital not only for an even surface but also to ensure a proper bond between the tar and chip. Another important consideration is the cleanliness of the stone chips you’ll be using.
Dirty or dusty chips won’t bind well with the molten liquid asphalt, so it’s essential to clean them first before laying them down. The key to success lies in spreading the chips quickly while the molten liquid asphalt is still hot. This ensures everything remains in place and held together.
Tar and chip driveway vs asphalt
The confusion between tar and chip, and asphalt stems from their shared origin in molten bitumen, a byproduct of petroleum. To gain clarity on their differences and similarities, it’s helpful to consider the following: Both tar and chip and asphalt are durable options, but while tar and chip typically lasts for 7-12 years, asphalt can endure for over three decades. Asphalt also boasts greater load-bearing capacity than tar and chip.
Furthermore, asphalt is available in a wider range of colors and offers a sleek black appearance. In terms of weather resistance, both options provide adequate protection, although asphalt is less susceptible to cracking compared to concrete. Tar and chip, on the other hand, is more prone to cracking. Notably, asphalt is generally more expensive than tar and chip, while still being a more affordable option compared to most concrete materials.
How to repair a chip and tar driveway
Tar and chip driveways are often said to possess a natural self-healing mechanism during the hot summer months. As the surface temperature rises, the finer layers of chipped material tend to soften and fill in minor dents and cracks. However, for added assurance and optimal results, it’s recommended that you inspect and potentially replenish the tar base, followed by an application of new chip material.
If you’re unsure about the best approach, consulting with a professional contractor can provide valuable insights.
