The overlay is typically two inches thick, creating a strong bond between layers and ensuring long-lasting performance. For the best results for any kind of asphalt repair, it’s best to hire a professional contractor who can make the appropriate recommendations and handle the repairs for you, ensuring that the work is properly executed.
You should resurface your asphalt driveway if the damage is limited to superficial cracks and minor deterioration, as renewing the top layer extends its life.
