Introduction
If you’re looking for a cost-effective, eco-friendly paving option, recycled asphalt millings might be the perfect solution. These millings are made from old asphalt that’s been ground up and reused, offering a durable surface without the high cost of fresh asphalt. In this guide, we’ll explain what asphalt millings are, where they work best, and the pros and cons of using them.
What Are Recycled Asphalt Millings?
Recycled asphalt millings are chunks or ground pieces of asphalt pavement removed during resurfacing or reconstruction projects. Instead of being discarded, these materials are crushed and reused as a substitute for gravel or new asphalt. They are compacted to form a stable surface for driveways, roads, or parking areas.
How They’re Made
- People take off old asphalt from roads and parking lots.
- It’s transported to a processing facility where it’s crushed and screened.
- The resulting product is compacted and sometimes mixed with a binding agent for better cohesion.
Advantages of Recycled Asphalt Millings
1. Cost-Effective
Millings are significantly cheaper than new asphalt or concrete, making them a smart, budget-friendly option for driveways and private roads.
2. Environmentally Friendly
Recycling old asphalt reduces trash in landfills and saves resources. It also reduces the carbon footprint of your project.
3. Durable and Low Maintenance
When properly compacted, asphalt millings create a durable, weather-resistant surface that resists cracking and shifting.
4. Excellent for Rural and Low-Traffic Areas
They’re ideal for long driveways, farm roads, and rural paths where a fully paved surface isn’t necessary.
5. Good Drainage
Millings allow for better water drainage than solid asphalt, helping reduce pooling and erosion.
Disadvantages of Recycled Asphalt Millings
1. Less Aesthetic Appeal
Millings can appear rough and dusty, lacking the smooth finish of fresh asphalt.
2. Loose Particles
Without proper compaction or a binding agent, the surface may shed particles or become uneven over time.
3. Not Ideal for High-Traffic Areas
Millings aren’t always the best choice for heavily trafficked urban areas or commercial parking lots.
4. May Need Regrading
Over time, weather and use may cause the surface to shift or develop ruts, requiring periodic regrading to maintain a level surface.
Best Uses for Asphalt Millings
- Driveways – A durable, affordable choice for residential properties.
- Private roads – Especially in rural or farm areas.
- Parking areas – Great for low-traffic zones.
- Trail and path construction – Millings provide a solid base with good drainage.
How to Install Recycled Asphalt Millings
- Clear and grade the surface – Remove any rubbish and level the area.
- Lay the millings – Spread them evenly across the surface.
- Compact the material – Use a vibratory roller to press the millings firmly into place.
- Optional: Apply a sealant or binding agent – This enhances durability and reduces dust.
Maintenance Tips
- Inspect regularly for low spots or ruts.
- Recompact if the surface loosens or shifts.
- Add new millings as needed to maintain a consistent thickness.
Conclusion
Recycled asphalt millings provide an affordable and environmentally conscious alternative to traditional paving materials. While they may lack the smooth polish of hot-mix asphalt, their durability and cost savings make them ideal for many residential and rural applications. Proper installation and occasional maintenance ensure a long-lasting surface that performs well in a variety of conditions.
