Summary:
Understanding Asphalt's Vulnerabilities on Long Island
To appreciate sealcoating, it helps to know what damages asphalt paving. Ultraviolet (UV) rays from the sun oxidize the asphalt binder (the black liquid holding it together), making it brittle and prone to cracking. Water penetration, through rain and snowmelt, seeps into pores and can weaken the underlying base, particularly with Long Island’s freeze-thaw cycles causing expansion and contraction. Additionally, vehicle fluids like oil and gasoline can soften and dissolve the asphalt binder.
Sealcoating as a Protective Shield Against Sun Damage
Sealcoating products form a barrier layer that shields the asphalt binder from the sun’s damaging ultraviolet (UV) radiation. By slowing down the oxidation process, the sealer helps the asphalt retain its flexibility for longer, making it less likely to become brittle and develop age-related surface cracks on your driveway paving.
Preventing Water Intrusion and Freeze-Thaw Issues
Sealcoating products form a barrier layer that shields the asphalt binder from the sun’s damaging ultraviolet (UV) radiation. By slowing down the oxidation process, the sealer helps the asphalt retain its flexibility for longer, making it less likely to become brittle and develop age-related surface cracks on your driveway paving.
Resisting Damaging Spills and Restoring Appearance
Sealcoating is made affordable with the use of chemical resistance. The sealed surface prevents automotive fluids like gasoline, oil, and antifreeze from penetrating and softening the asphalt binder, which can lead to rapid deterioration. Beyond protection, sealcoating also offers a significant aesthetic benefit by restoring the deep, black finish of new asphalt, creating a uniform appearance for your driveway.
Filling Hairline Cracks and Halting Minor Damage
While not a substitute for proper asphalt repair of larger cracks, sealcoating does fill very fine, hairline surface cracks. By sealing these tiny openings in your pavement, it blocks the collection of water and debris, which otherwise accelerate into larger, more problematic cracks requiring more involved intervention. This action helps stop minor imperfections from escalating into significant damage that compromises the structure.
The Smart Economics of Preventative Sealcoating
Sealcoating is considered affordable because its cost is minor compared to the expense of major asphalt repair or complete asphalt resurfacing. Regularly applying sealant (typically every 2-4 years, depending on conditions) is a maintenance investment. It delays the onset of major deterioration, pushing back the need for costly repairs or premature replacement, thereby extending the useful life of both residential paving and commercial paving surfaces for long-term value.
