Asphalt over time can wear down due to weathering, oxidation, and the destructive softening effect of gasoline, oil and other chemicals. Without proper protection the surface oxidizes, allowing the aggregate in the asphalt mix to wash away. Unprotected asphalt loses desired resiliency, aggregate ravels from the surface, the pavement roughens, and the surface becomes brittle. This causes cracks and sub-base damage. Unfilled cracks allow water to saturate the sub-base rupturing the pavement and turns cracks into potholes. This can lead to costly repairs and may require a pre-mature asphalt overlay. Asphalt should be sealcoated every 3-5 years depending on weather and traffic conditions. Sealcoating extends the life of your asphalt pavement.
Benefits of sealcoating:
Prevents gas, oil and other chemical damage
Slows down weather damage
Restores color to pavement “curb appeal”
Protects your investment!
