Q: What is the best grade of asphalt?

• <div><p>There&rsquo;s no single best asphalt grade&mdash;it all comes down to where and how it&rsquo;s used. Highways and heavy-traffic roads need something tough, like polymer-modified asphalt (PMA) or Stone Matrix Asphalt (SMA). Local roads and parking lots rely on the Performance Graded (PG) system, chosen based on climate. A PG 64-28 mix, for example, handles a broad temperature range while simpler, more cost-effective mixes are typically enough for residential driveways. The best grade of asphalt depends on traffic, weather, and your budget, which is why a professional&rsquo;s input is always a smart move before making a decision.</p></div>

There’s no single best asphalt grade—it all comes down to where and how it’s used.

Question 2

Is three inches of asphalt enough depth for a driveway?

Accepted Answer

•

Three inches is a great thickness for a residential asphalt driveway that sees minimal to moderate traffic from cars, SUVs, and pickup trucks. However, a thicker driveway can better withstand the weight of a heavier vehicle, such as a trailer or a recreational vehicle. If you drive a heavy vehicle on a thin driveway, you risk cracking and damaging it.

Question 3

What is the difference between travertine tiles and travertine pavers?

Accepted Answer

•

Generally speaking, tiles are for indoor use, while pavers are for outdoor use. The main difference between travertine tiles and pavers is their thickness. Tiles are around 1/2 inch thick, and pavers are 1 1/4 inches to 2 inches thick.

Pavers are more rugged and can handle different weather. The extra thickness on pavers also makes them ideal for high-traffic areas.

Question 4

Is it worth it to build a cobblestone driveway?

Accepted Answer

•

Cobblestone driveways can take a major hit on anyone's bank account, begging the question of whether it's worth it to build a cobblestone driveway. Some homeowners might prefer more affordable driveway materials like concrete or pavers, which can give a similar appearance to cobblestone without the high price tag.

Paving your driveway costs between $2,500 and $6,600, to put that in perspective. But for others, there’s nothing quite like the timeless look of cobblestone driveways.

Question 5

What is box fill?

Accepted Answer

•

Box fill refers to the maximum number of conductors that can be contained within a wiring enclosure box, as well as the total volume of the components. Determining the allowable number of conductors in a box requires adding up the number of conductors, clamps, support fittings, devices and equipment, and equipment grounding conductors to make sure you’re within the allowable volume.
