How long does asphalt last in Florida?
Typical lifespan of asphalt driveways, parking lots and streets in South Florida, what shortens it, and how to tell when to repair or resurface.
Typical lifespan
A well-built asphalt pavement in South Florida commonly lasts around fifteen to twenty years or more before it needs resurfacing, with regular crack sealing and sealcoating. A poorly built one can fail in a few years. The range is wide because lifespan depends far more on the base, drainage and maintenance than on the asphalt itself.
What shortens it
Water in the base is the number one cause: from cracks left open, ponding, or drainage that sends runoff under the pavement. Next is base that was never properly compacted. Then UV oxidation, which dries and embrittles the surface, and heavy loads on pavement not designed for them, such as garbage trucks on a thin residential section.
What extends it
Compacted limerock base of the right thickness, slope that sheds water, crack sealing every year or two, sealcoat every two to three years, and fixing small failures before they spread.
Repair, overlay or replace?
Scattered potholes and cracks over a sound base: repair and seal. Widespread surface cracking and raveling but no base failure: mill and resurface. Widespread alligator cracking, rutting and pumping: the base has failed and full-depth reconstruction is the honest answer.
Common questions
Does asphalt last longer than concrete?
Concrete generally lasts longer with less maintenance, but costs more and is harder to repair. Asphalt is cheaper, faster and easier to patch.
Does Florida heat damage asphalt?
Heat softens fresh asphalt and UV oxidizes it over time. Sealcoat slows the oxidation.
