There’s no single best asphalt grade—it all comes down to where and how it’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’s input is always a smart move before making a decision.

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.

Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.

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.
