Specific Weight of Asphalt Millings: Weight of 1 m³, Density and Reference Table
Asphalt millings (also called reclaimed asphalt pavement or asphalt granulate) are a recycled road construction material obtained by crushing or cold milling old asphalt pavement. The material consists of crushed stone, sand, mineral filler and residual bitumen.
The technological value of asphalt millings is due to the remaining bitumen, which improves the bonding of particles after compaction. As a result, the material is widely used for road construction and repair, temporary access roads, parking areas, shoulder reinforcement and pothole repairs.
Typical applications include:
- construction of temporary roads and access routes;
- reinforcement of road shoulders and slopes;
- repair of potholes and damaged pavement;
- preparation of base layers for road surfaces.
Asphalt Millings Density Table
Although many users search for the “specific weight of asphalt millings”, engineering calculations usually rely on the material density.
Specific Weight and Weight of 1 m³ of Asphalt Millings
| Material | Density (g/cm³) | Weight of 1 m³ (kg) |
|---|---|---|
| Asphalt millings | 1.5–1.9 | 1500–1900 |
The actual value depends on particle size distribution, compaction level and residual bitumen content.
Specific Weight Calculation
Specific weight is calculated using:
γ = ρ × g
where γ is the specific weight, ρ is density, and g is the gravitational acceleration (9.81 m/s²).
In practical engineering calculations, density expressed in kg/m³ is used more frequently.
Density of Asphalt Millings
Density represents the mass contained in one cubic meter of material. It depends on particle size, compaction, residual bitumen and moisture content.
For most applications, asphalt millings have a density of 1500–1900 kg/m³. A value of 1.5 t/m³ can be used as an approximate estimate for preliminary calculations.
Conclusion
The density of asphalt millings generally ranges from 1500 to 1900 kg/m³, corresponding to a weight of 1500–1900 kg per cubic meter. For precise engineering calculations, use the characteristics of the specific material being supplied.
Frequently Asked Questions
How much does 1 m³ of asphalt millings weigh?
In most practical calculations, 1 m³ of asphalt millings weighs about 1500–1900 kg. A value near 1500 kg/m³ is often used for rough estimates, but the actual weight depends on gradation, moisture, residual bitumen and compaction.
Why do loose and compacted asphalt millings have different weights?
Compaction reduces the voids between particles, so more material fits into the same volume. That is why 1 m³ of compacted asphalt millings usually weighs more than loose material.
Can the table be used to estimate delivery volume and truck loads?
Yes, the table is suitable for preliminary estimates of mass and truck loads. For ordering and transport limits, use the bulk density of the specific batch provided by the supplier.
