You can expect your asphalt pavement to last anywhere from 20 to 30 years, or 25 years on average. The life expectancy of your asphalt driveway depends on the climate, the amount of traffic, and how well you maintain it. While you can’t necessarily control some of these factors, you can control the amount of maintenance effort you put into your driveway. 

To prevent your asphalt from deteriorating prematurely, you should follow a good maintenance routine involving regular cleaning, reparation work, and resealing.

You should place a layer of thick landscaping fabric directly over the concrete slab and then a thin layer of leveling sand over that to protect the pavers from moisture. For border pavers, you should plan on locking them in place with polyurethane adhesive. This will prevent them from shifting under foot traffic.

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.

To adhere pavers to concrete, you can use either mortar or a concrete-specific adhesive. For border pavers, a polyurethane-based adhesive is a good choice as it expands and contracts with temperature changes, keeping them firmly in place. For the non-border pavers, polymeric sand is used between the joints to prevent shifting. In most cases, it is also recommended to lay a permeable sand layer below the pavers to ensure proper stability and drainage. Before starting, always take the proper preparatory steps for a professional result.
