What Is Asphalt Milling
Asphalt milling removes the top layer of pavement at a controlled depth to correct grade issues, smooth surface irregularities, and prepare the area for a new overlay. Cold planers grind the asphalt into a consistent profile, with milling depths typically ranging from half an inch to several inches.
Milling is effective when the surface is worn but the base remains stable. It maintains proper elevations and curb reveal at transitions, drains, and ADA-accessible areas while creating a level foundation for resurfacing. The removed material can also be recycled or incorporated into asphalt reclamation processes on larger rehabilitation projects.
What Is Asphalt Resurfacing
Asphalt resurfacing, often called an overlay, places a new asphalt layer over a prepared surface. It is a sensible option for commercial asphalt resurfacing projects where the pavement exhibits surface wear, cracking, or fading but lacks deeper structural issues. Most overlays range from 1.5 to 3 inches thick, depending on traffic demands.
A resurfaced pavement can provide 8 to 15 years of service with routine maintenance. It also improves appearance, drivability, and overall performance.
What Does It Mean to Repave Asphalt
Repaving is recommended when pavement damage extends below the surface, and the structure can no longer support daily traffic. Depending on the level of deterioration, the work may involve partial-depth or full-depth removal.
Partial-depth repaving replaces only the upper asphalt layers, while full-depth repaving rebuilds both the pavement surface and its supporting base. These improvements restore the strength needed for commercial traffic, delivery routes, and heavier equipment.
Preparation may also include targeted repairs such as skin patches for shallow distress, partial-depth patches for moderate failures, and full-depth patches for severe or structural damage. These steps help ensure the pavement is ready for long-term performance as part of Finley’s broader asphalt repair capabilities.
