Q: What maintenance is required for new asphalt?

• <div><p>Regular cleaning, sealing, and timely repair of cracks help maintain its condition.</p></div>

Q: Is a 20% slope too steep for a driveway?

• <div><p>While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you&rsquo;re laying a driveway that is up to code for your location. </p></div>

Q: Is asphalt the same as tarmac?

• <div><p>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&mdash;a byproduct of crude oil&mdash;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 &ldquo;tarmac&rdquo; are actually asphalt. So, while the names may overlap, the key distinction lies in the binder&mdash;tar for tarmac and bitumen for asphalt.</p></div>

Q: What is the price of a gravel vs. asphalt driveway?

• <div><p>Gravel driveways are significantly more affordable than asphalt driveways, making them an enticing financial decision when choosing your next driveway material. On average, gravel driveways are <b>$5.75 to $13 per square foot </b>cheaper than asphalt driveways. </p><p>It's not just their price that makes gravel driveways more economical. Gravel driveways also can last up to 100 years with minimum maintenance, whereas asphalt driveways only last for 15 to 30 years with proper maintenance. But if you&rsquo;re looking for the <a href="https://www.angi.com/articles/best-driveway-material-for-cold-weather.htm">best driveway material for cold weather</a>, asphalt may be a better choice.</p></div>

Antonio and his crew are wonderful to work with. They redid our driveway retaining walls with a beautiful stacked natural fieldstone. Communication of the scope and budget was very clear and there were no surprises. The workmanship is top notch. I highly recommend Bolani Masonry.
