Asphalt Pot Hole Repair

When asphalt potholes and localized damage go unrepaired, the structural health of the pavement deteriorates through a predictable sequence of failure:

1. Sub-Base Erosion: Unsealed potholes act as funnels, allowing rainwater and surface runoff to flow straight into the aggregate sub-base beneath the asphalt. This moisture softens, washes away, and weakens the underlying soil foundation that supports vehicle weight.
   
2. Expansion and Alligator Cracking: As vehicles drive over the weakened, hollowed-out sub-base, the unsupported asphalt edges surrounding the pothole flex and snap. The initial hole rapidly widens and deepens, while surrounding areas break into interconnected "alligator" cracks that spread across the lot.
   
3. Freeze-Thaw Destabilization: In cold climates, trapped water freezes and expands under the pavement, heaving the asphalt upward. When the ice melts, void spaces remain, causing massive sections of the surrounding pavement to collapse.
   
4. Complete Foundation Failure: Over time, localized surface defects turn into widespread base failure. Once the sub-base is compromised across large areas, basic patching is no longer effective. The property owner is forced to pay for a full removal and sub-base reconstruction—a capital expense that can cost up to 3 to 5 times more than timely patching.
   
5. Surmounting Liability and Vehicle Damage: Beyond structural costs, deep unrepaired potholes create immediate trip-and-fall liability, disrupt ADA compliance, and cause severe vehicle damage like blown tires, bent rims, and misaligned suspensions.
