Gravel is the cheapest way to extend a driveway. Gravel is an affordable, practical option that’s easy to install and perfect for DIY projects, helping you save on labor costs. It can be quickly spread and leveled to create extra driveway space without heavy preparation. While gravel doesn’t offer the same durability or finished look as concrete or asphalt, its low cost makes it ideal for budget-conscious homeowners who want a functional solution without overspending.

Yes, a paved or repaved driveway can boost your home's value by increasing its curb appeal and the functionality of your outdoor space. A new driveway can add anywhere from $5,000 to $20,000 to a property's value. An old, crumbling driveway can be a red flag for potential buyers and inspectors.

The amount of value added depends on the materials used, the design, and local market conditions. Concrete is often cited as adding the most value due to its long lifespan, though asphalt may be more desirable in colder climates. The return on investment is greatest when replacing a driveway that is in poor condition; repaving a driveway that is already in good shape will not yield as significant an increase in value.

Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

The choice between asphalt and concrete depends on your priorities, budget, and climate.

Concrete is generally more durable, lasting up to 50 years with minimal upkeep, and offers more customization options like staining and stamping, which can add more to a home's value. However, it is more expensive upfront and can be prone to cracking in cold climates where water can freeze and expand.

Asphalt is typically cheaper and quicker to install and is easier to repair. It performs better in colder climates. However, it requires more maintenance, including regular resealing, has a shorter lifespan, and can get hot and sticky in intense sunlight.

Ultimately, if durability and long-term value are key, concrete is often the better choice. If upfront cost and performance in cold weather are more important, asphalt may be preferable.
