Wet cutting is usually the preferred method. It controls dust, which helps protect your lungs and makes for a cleaner working environment. Plus, the water cools the blade, preventing overheating and prolonging its life while providing smoother, more precise cuts. The downside is the mess—water and asphalt sludge can be messy to clean. Dry cutting, though convenient if water isn’t available, creates a lot of dust, which can be harmful. This also increases the risk of blade damage due to overheating. So, if you have the option, wet cutting is the better method for most asphalt jobs.

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.

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.

To ensure you hire a reliable and experienced paving company, you should start by finding companies in your area that have at least five to ten years of experience working in your neighborhood. Next, rule out companies with poor reviews online or a series of complaints filed with the Better Business Bureau. Since driveways affect your curb appeal, you should also ask each company for references and pictures of recent work to make sure the work the company does is professional and high quality. Finally, check that the company is licensed and insured.
