A driveway's lifespan varies by material. Asphalt driveways typically last 15 to 30 years, while concrete driveways last longer, between 20 and 50 years. The longevity of any driveway is affected by factors like extreme temperatures, heavy traffic, and the quality of maintenance. Regular upkeep, such as filling cracks, resealing the surface, and ensuring proper drainage, can help extend its life. For gravel driveways, regrading to fill in uneven areas every year or two is recommended.

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.

If your new pavers look dull or unclean, it is likely due to efflorescence, a chalky, white powder that forms when lime in the pavers gets wet. This condition often resolves on its own, as rain will naturally wash it away within about a year. For faster results, you can use a pressure washer to clean the pavers. Alternatively, consider using cleaning products specifically designed to remove efflorescence or applying sulfuric acid crystals.

You can pour concrete over asphalt if it’s in good condition, thick, stable, and well-compacted. Concrete is more durable than asphalt and can extend the lifetime of your driveway without having to pay frequent asphalt driveway repair costs or replace it completely. 

But this is best reserved as a temporary solution based on budget restraints, as asphalt requires more frequent repairs and assessments than concrete. Once that concrete top is poured, it’ll be harder to accurately understand what’s happening beneath that layer, which could lead to more issues.
