Common Milling Depths & Applications
How to Use This Asphalt Milling Calculator
Measure Your Project Area
Measure the length and width of the area to be milled. For irregular shapes, break them down into rectangles and calculate each separately.
Determine Required Milling Depth
The milling depth depends on the condition of the pavement and the purpose of milling. Common depths range from 1 to 4 inches for standard applications, with deeper milling for full reconstruction.
Select Milling Type
Different milling types have different applications and costs. Standard milling is most common, while micro-milling provides a smoother surface, profile milling addresses specific contours, and full-depth removal is for complete reconstruction.
Enter Cost Per Square Foot
Milling costs vary by location, project size, and complexity. Contact local contractors for current rates, or use our default value as an estimate.
Asphalt Milling Applications
Pavement Rehabilitation
Milling removes deteriorated surface layers before applying a new overlay, extending pavement life at a fraction of the cost of full reconstruction.
Profile Correction
Milling can correct surface irregularities, improve drainage patterns, and restore proper cross-slopes for better water runoff.
Curb Reveal Restoration
After multiple overlays, curb height can be diminished. Milling removes excess asphalt to restore proper curb height for drainage and safety.
Material Recycling
Milled asphalt (Reclaimed Asphalt Pavement or RAP) can be recycled into new asphalt mixes, reducing costs and environmental impact.
Utility Adjustments
Milling provides access to buried utilities and manholes that need adjustment before new pavement is applied.
Typical Milling Costs by Project Type
| Project Type | Typical Depth | Cost Range (per sq ft) | Considerations |
|---|---|---|---|
| Residential Street | 1-2 inches | $1.00 - $2.00 | Utility adjustments, driveway transitions |
| Commercial Parking Lot | 2-3 inches | $1.25 - $2.50 | Drainage patterns, traffic flow during work |
| Highway/Arterial Road | 2-4 inches | $1.50 - $3.00 | Traffic control, night work requirements |
| Full-Depth Removal | 4-6+ inches | $2.50 - $4.00 | Base repairs, longer project duration |
Frequently Asked Questions
Asphalt milling (also called cold planing) is the controlled removal of the surface layer of asphalt pavement using specialized equipment called a milling machine. The process creates a textured surface that provides excellent bonding for new asphalt layers. Milling is typically performed as part of pavement rehabilitation projects to remove damaged or deteriorated asphalt before applying a new surface layer.
This calculator provides a good estimate based on industry averages and the information you provide. However, actual quantities and costs can vary based on local conditions, contractor pricing, and specific project requirements. Factors such as pavement condition, access constraints, and mobilization costs may affect the final price. We recommend getting quotes from local contractors for the most accurate pricing.
Milled asphalt material, known as Reclaimed Asphalt Pavement (RAP), is typically recycled. It can be:
- Incorporated into new asphalt mixes (reducing the need for virgin materials)
- Used as a base material for roads, parking lots, or driveways
- Used for temporary roads or paths
- Used as fill material for various construction applications
The duration of the milling process depends on several factors, including the size of the project, milling depth, and equipment used. As a general guideline:
- A standard milling machine can typically mill 10,000-20,000 square feet per day at a 2-inch depth
- Smaller residential projects might be completed in a single day
- Larger commercial or highway projects may take several days or weeks
Yes, milled surfaces are generally safe to drive on for short periods, though they provide a rougher ride than finished pavement. However, there are some considerations:
- Reduced skid resistance in wet conditions
- Potential for loose debris
- Exposed utility structures may create hazards
- Reduced comfort due to the textured surface
