Asphalt is known for its strength, flexibility, and affordability — but even the most durable pavement is not invincible. Over time, environmental factors, heavy traffic, and lack of maintenance can take their toll. Understanding the most common causes of asphalt damage can help homeowners and property managers prevent costly repairs and extend the life of their pavement.
At Paterson Asphalt Paving, we’ve seen every type of asphalt problem imaginable. From cracks and potholes to surface fading and drainage issues, most pavement damage can be traced back to a few key causes. This guide explains those causes, why they occur, and what you can do to stop them before they worsen.
1. Water Damage
Water is asphalt’s worst enemy. While asphalt itself is water-resistant, cracks and openings allow water to seep into the base and sub-base layers, where it causes erosion, softening, and eventual failure.
During winter, trapped water can freeze and expand — breaking the pavement apart through the freeze-thaw cycle. Over time, this leads to widespread cracking, potholes, and structural instability.
Proper drainage design and regular sealcoating are key to preventing water infiltration. Sealcoating acts as a waterproof barrier, while proper grading ensures water flows away from the surface.
Tip: Check for standing water after rainfall. If puddles remain for more than a few hours, it’s time to consult a professional for drainage correction or resurfacing.
2. Poor Drainage Design
Inadequate drainage is one of the most preventable causes of asphalt deterioration. Without a proper slope, water can pool on the surface or seep into the foundation, undermining the structure from below.
For parking lots, driveways, or roadways, a slope of at least 1–2% (or ⅛ to ¼ inch per foot) is recommended to promote effective runoff. If this isn’t achieved during installation, water damage is inevitable.
Our asphalt paving experts at Paterson Asphalt Paving carefully evaluate each site to ensure optimal grading and water management before installation.
| Drainage Issue | Effect on Pavement | Solution |
| Standing water | Weakens surface and sub-base | Regrading or milling |
| Blocked drains | Causes flooding and cracking | Drain cleaning and maintenance |
| Poor slope | Accelerates erosion | Re-leveling or new drainage system |
Preventive Measure: Schedule a yearly inspection to assess drainage effectiveness, especially after winter seasons or heavy storms.
3. Heavy Traffic Loads
Asphalt is designed to handle a specific amount of weight and pressure. When subjected to heavier vehicles or constant high-volume traffic, the surface can deform, rut, or crack.
Over time, the pavement begins to compact unevenly, leading to depressions and structural fatigue. For commercial lots, delivery routes, or industrial zones, thicker asphalt layers and reinforced sub-bases are required.
At Paterson Asphalt Paving, we tailor each project to its intended use — ensuring that the pavement thickness, material mix, and compaction meet load-bearing requirements.
Tip: If your asphalt frequently supports heavy trucks or machinery, consider periodic asphalt resurfacing to restore strength and smoothness.
4. UV Rays and Oxidation
Sunlight may seem harmless, but ultraviolet (UV) radiation gradually breaks down asphalt’s chemical bonds. The process, known as oxidation, dries out the asphalt binder, making the surface brittle and prone to cracking.
This damage is visible as color fading — asphalt turns from deep black to dull gray over time. As the surface hardens, small cracks appear, eventually leading to major deterioration.
Regular sealcoating restores the protective layer that shields asphalt from UV exposure, keeping it flexible and resilient.
Preventive Measure: Apply sealcoat every 2–3 years to preserve color, elasticity, and strength.
5. Improper Installation
No amount of maintenance can compensate for a poor installation. When asphalt is installed without proper base preparation, compaction, or temperature control, problems arise quickly.
Common installation errors include:
- Insufficient base thickness, leading to soft spots and rutting
- Uneven compaction, which causes surface waves or depressions
- Incorrect asphalt temperature, resulting in weak bonding between layers
At Paterson Asphalt Paving, we follow precise installation standards — from sub-base grading to rolling — to ensure durability from the ground up.
Tip: Always choose a licensed, experienced contractor who follows best practices for compaction, drainage, and layer thickness.
6. Freeze-Thaw Cycles
In regions like New Jersey, where winter temperatures frequently drop below freezing, freeze-thaw cycles are a major contributor to asphalt damage.
When moisture seeps into cracks and freezes, it expands by nearly 10%, widening the cracks and loosening the surrounding materials. As the ice melts, it leaves behind voids that weaken the structure — and the cycle repeats.
Over time, this constant expansion and contraction lead to potholes, raveling, and surface crumbling.
Preventive Solution: Regular crack filling and sealcoating help prevent moisture infiltration and freeze-thaw damage.
7. Lack of Regular Maintenance
Even the best asphalt surface requires maintenance. When small issues go unchecked, they quickly escalate into major damage.
Neglecting maintenance often results in:
- Widening cracks and surface unraveling
- Potholes caused by unfilled voids
- Oxidation and fading
- Uneven wear from vehicle traffic
Routine asphalt maintenance is affordable and saves thousands over time. Simple steps like crack sealing, resurfacing, and sealcoating can double your pavement’s lifespan.
| Maintenance Task | Frequency | Purpose |
| Sealcoating | Every 2–3 years | Protects from UV and moisture |
| Crack Filling | As needed | Prevents water infiltration |
| Pothole Repair | Immediately | Avoids spreading damage |
| Resurfacing | Every 10–15 years | Restores appearance and strength |
Tip: Create a maintenance schedule after installation to prevent unexpected costs and early failure.
8. Oil and Chemical Spills
Oil, gasoline, and other automotive fluids can soften the asphalt binder, causing it to break down. This leads to discoloration, soft spots, and surface erosion.
These chemicals penetrate the asphalt surface and dissolve the bitumen, leaving behind weak, crumbly patches that easily crumble under weight.
The best defense is immediate cleanup. Use absorbent materials like sand or kitty litter to soak up spills, followed by professional cleaning or spot sealing.
Preventive Measure: For commercial parking lots, applying an extra coat of sealant adds a layer of protection against oil and chemical penetration.
9. Tree Roots and Vegetation
Tree roots growing beneath or near the pavement can lift and crack the asphalt from below. Even small roots can exert enough pressure to create visible bumps or surface separations.
Additionally, grass and weeds growing through cracks can widen them over time by holding moisture against the asphalt.
Before installation, our experts evaluate nearby vegetation and recommend root barriers or pre-treatment to prevent future interference.
Tip: Keep vegetation trimmed back, and remove weeds growing through pavement joints.
10. Aging and Natural Wear
All pavement eventually wears out with time. Exposure to weather, sunlight, and traffic naturally causes aging. Over the years, asphalt loses its flexibility and develops surface cracks, fading, and roughness.
While aging is inevitable, proper maintenance dramatically slows it down. Asphalt resurfacing restores appearance and strength without the need for full replacement.
Preventive Measure: Schedule a professional inspection every few years to identify aging signs early and address them before major repairs are needed.
11. Sub-Base Failure
A weak or shifting sub-base is another major cause of pavement distress. When the foundation under the asphalt becomes unstable — often due to poor compaction, erosion, or water intrusion — the surface begins to crack and sink.
This typically appears as alligator cracking — a network of interconnected cracks resembling reptile scales.
Repairing sub-base failure often requires full-depth reconstruction, but regular inspection and prompt maintenance can prevent it from reaching that stage.
At Paterson Asphalt Paving, we use high-quality materials and proven installation techniques to build strong, well-compacted foundations that resist long-term movement.
12. Extreme Temperature Fluctuations
Temperature changes throughout the year cause asphalt to expand and contract. When this happens repeatedly, small surface fractures can develop into larger cracks.
In hot weather, asphalt softens and may rut under heavy loads; in cold weather, it hardens and becomes more brittle.
Preventive Measure: Applying a high-quality sealcoat helps maintain flexibility and prevents temperature-related cracking. For commercial projects, choosing the right asphalt mix also improves resistance to temperature stress.
13. Overloading and Improper Use
Asphalt surfaces are designed for specific purposes. When used beyond their intended capacity — such as parking heavy construction vehicles on a residential driveway — deformation and cracking are inevitable.
Overloaded areas experience base compression, leading to ruts or sinkholes. Ensuring proper design thickness during installation prevents this issue from the start.
If overloading is unavoidable, periodic asphalt resurfacing can help reinforce the surface.
