Cold milling and overlay is a cost-effective technique that addresses surface-level pavement issues while preserving the underlying structure. Understanding the costs involved in this process will help you budget appropriately and make informed decisions for your pavement maintenance.

What Is Asphalt Milling?

Asphalt milling (also called cold milling) is a controlled process that removes a predetermined depth of existing asphalt surface using specialized milling equipment. This creates a textured surface that serves as an excellent bonding platform for a new layer of asphalt overlay. The process addresses surface defects while maintaining proper curb heights and drainage patterns.

Average Cost to Mill Asphalt

Asphalt milling is typically priced by square yard or by lane mile. Keep in mind that the figures given below represent averages and may vary based on the requirements of your specific projects and current market conditions.

Per Square Yard

• Basic milling (1-2 inches deep): $2.50 to $5.00 per square yard

• Medium-depth milling (2-4 inches): $5.00 to $8.00 per square yard

• Deep milling (4+ inches): $8.00 to $12.00 per square yard

Per Lane Mile

• Standard 12-foot lane, 2-inch depth: $20,000 to $35,000 per mile

• Standard 12-foot lane, 3-inch depth: $30,000 to $45,000 per mile

• Standard 12-foot lane, 4-inch depth: $40,000 to $60,000 per mile

Factors Affecting Asphalt Milling Costs

Depth of Milling

The depth of milling massively impacts overall project costs. Shallow milling (one to two inches) is sufficient for surface corrections and preventative maintenance. On the other hand, deeper milling addresses more severe structural issues.

Each additional inch of depth increases equipment demands, processing time, and material handling requirements, which directly affects your project budget. 

Project Size & Scale

Economies of scale apply strongly to milling operations. Larger projects typically benefit from lower per-unit costs, since mobilization expenses are distributed across more square yardage.

Small projects under 5,000 square yards may face higher per-yard costs since equipment mobilization and setup costs will represent a larger percentage of the total project expense. 

Traffic Control & Lane Closures

Projects on busy roadways or commercial properties need comprehensive traffic management plans. These can include:

• Flagging crews
• Temporary signage
• Barricades and cones
• Electronic message boards

These safety measures increase overall project costs, but they’re vital for protecting public safety and staying in compliance with Michigan Department of Transportation (MDOT) regulations.

Additionally, night work to minimize traffic disruption on major Michigan highways typically commands premium rates of 15-30% above standard pricing. 

Equipment & Labor Costs

Milling machines are sophisticated pieces of equipment that require skilled operators. Don’t forget to account for these expenses in your project budget. Such costs include:

• Equipment rental and/or utilization fees
• Operator labor costs
• Support equipment like sweepers, water trucks, or loaders
• Fuel and maintenance expenses

Michigan’s seasonal construction market can affect labor availability and costs, with peak season (May through October) typically bringing higher rates due to demand. Plus, the brief construction window in Michigan’s climate means you should schedule your project early to secure optimal prices. 

Disposal & Recycling Fees

Milled asphalt material requires proper handling. While most milled material is recyclable, transportation and processing costs apply, including:

• Hauling costs to recycling facilities
• Processing fees
• Environmental compliance expenses with Michigan EGLE requirements

Working with contractors who maintain their own recycling capabilities (like Michigan Paving & Materials) can reduce these costs while boosting your project’s sustainability. 

How to Save on Your Asphalt Milling Project

1. Partner With a Local Contractor

Choosing a Michigan-based contractor like Michigan Paving & Materials reduces transport costs and supports businesses familiar with local conditions and regulations. Michigan’s freeze-thaw cycles require specialized knowledge of appropriate milling depths and overlay specifications so you get the longest-lasting results.

Additionally, local contractors typically maintain relationships with nearby material suppliers and recycling facilities, which further reduces your logistics costs. Michigan Paving & Materials operates multiple asphalt plants across the state, which translates to fresh materials and reduced transportation expenses for your project. 

2. Consider Milling vs. Full Replacement

For many pavement rehabilitation projects, milling and overlay provides most of the benefits of a full replacement at around half the cost. As long as the underlying structure is sound, the milling and overlay process addresses surface issues while preserving most of your existing pavement investment. This is particularly cost-effective for preventative maintenance. 

Michigan’s freeze-thaw cycles accelerate pavement deterioration, so regular milling and overlay programs can extend pavement life at a fraction of the cost. It’s an easy way for municipalities and commercial properties to maximize their maintenance budgets. 

3. Plan for Optimal Timing

Scheduling your project during Michigan’s shoulder seasons (late April through early May or September through October) may result in better pricing since contractors will be looking to fill their schedules during less busy periods. Additionally, bundling multiple properties or coordinating with nearby businesses for joint projects can improve economies of scale. 

Planning ahead by three to six months is highly recommended to secure your contractor at an optimal price. 

How to Choose the Right Contractor

Selecting the right asphalt contractor is vital for your project to succeed in Michigan’s challenging climate. Look for:

• Experience and reputation: Companies with track records in Michigan, like Michigan Paving & Materials, understand local conditions and regulations. Look for a contractor with experience in your specific region of Michigan.

• Equipment capabilities: Modern, well-maintained equipment yields high-quality results. Michigan’s short construction season demands contractors with reliable equipment that can perform efficiently within tight timeframes.

• Material production facilities: Contractors like Michigan Paving & Materials who produce their own materials often deliver better quality control and pricing.

• Sustainability practices: Companies that recycle and reuse materials demonstrate environmental responsibility and often provide cost advantages. 

• Complete services: Contractors offering both milling and paving services provide seamless project completion without the challenges of coordinating multiple vendors.

• Winter prep expertise: Michigan’s harsh winters need special considerations for pavement surfaces. Experienced contractors understand how to properly prepare surfaces for winter conditions to minimize damage from freezing and thawing, not to mention snow removal.
