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.

A pallet of pavers will cost about $300 to $700 per pallet. Each pallet covers about 56 square feet. The specific price you pay per pallet of pavers will depend on a few factors, including the type of paver you’re buying, the size and shape of the pavers, and how many pavers you need. In some cases, you’ll spend less per pallet if you’re buying in bulk for very large paver patios.

The most common causes of sunken pavers are poor base preparation and insufficient compaction. The problem could also be how your pavers were installed. If the soil beneath your patio or walkway wasn't compacted, it will pull pavers down as it settles. Additionally, using bare soil instead of making a paver bed with compacted gravel and sand can cause sinking over time. To fix sunken pavers, consider recompacting the base and addressing any drainage or erosion issues in the area.

After removing existing moss, consider using paver blocking sand to fill the joints. This specialty material hardens once placed and serves as an effective barrier against moss and weeds. From there on, regularly clean your pavers and try to keep them dry. You can also seal your paver as a semi-permanent solution — just make sure you reseal every 3 to 5 years.
