South Jersey's weather creates a uniquely challenging environment for asphalt driveways and parking lots. With hot, humid summers, cold winters with frequent freeze-thaw cycles, approximately 45 inches of annual rainfall, coastal influences, and intense UV exposure, local asphalt surfaces face more environmental stress than most regions. Harrison Paving has been installing and maintaining asphalt across South Jersey since 1985. Here is how each weather factor affects your pavement and what you can do about it.
South Jersey logs abundant sunshine from May through September, and ultraviolet radiation is one of asphalt's worst enemies. UV rays break down the petroleum-based binder that holds the aggregate together — a process called oxidation. You can see oxidation happening when your driveway gradually changes from dark black to medium gray. As oxidation progresses, the surface becomes brittle and develops hairline cracks that allow water entry. South Jersey's summer temperatures also soften asphalt surfaces, making them vulnerable to scuffing from turning tires and indentation from kickstands, jack stands, or heavy loads parked in one spot. Professional sealcoating every two to three years blocks UV damage and prevents oxidation.
South Jersey receives an average of 45 inches of rain annually, plus occasional nor'easters and tropical storm remnants that can dump several inches in a single event. Water is the primary enemy of asphalt pavement because it attacks from both above and below. Surface water enters through cracks and pores, reaching the crushed stone base where it weakens the foundation. Heavy rainfall can also erode unprotected driveway edges and wash away shoulder material that supports the pavement edge. Proper grading, sealcoating, crack filling, and drainage management are your defenses against water damage.
South Jersey experiences 30 to 50 freeze-thaw cycles per winter, where temperatures cross the 32-degree threshold repeatedly. This is actually more damaging than consistently cold regions where the ground freezes once and stays frozen until spring. Each cycle causes trapped water to expand and contract, progressively widening cracks and creating potholes. The areas of South Jersey with clay soils (common in Gloucester County) experience additional damage from frost heaving, where the expanding ice in water-saturated clay pushes the driveway surface upward.
Winter deicing chemicals affect South Jersey driveways both directly from homeowner application and indirectly from road salt splash carried by passing traffic. Sodium chloride degrades the asphalt binder over time and accelerates surface deterioration. Properties near busy roads or intersections where salt trucks make frequent passes experience more chemical exposure. Using calcium chloride instead of rock salt and applying it sparingly reduces this impact.
Shore community properties face additional challenges including salt spray from ocean winds, higher humidity that prolongs surface moisture contact, and occasional storm surge that deposits sand and salt water on paved surfaces. These factors can accelerate surface deterioration and require more frequent maintenance scheduling.
The most effective strategy against all weather-related asphalt damage in South Jersey is a combination of quality initial installation with proper base preparation, regular sealcoating every two to three years, prompt crack filling before winter, proper drainage maintenance, and careful snow removal practices. This maintenance program costs a fraction of premature replacement and can double your driveway's effective lifespan.
