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
Can the density of asphalt millings be used for precise calculations?
The density and weight values for asphalt millings in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of asphalt millings differ from the table?
The actual weight of asphalt millings depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of asphalt millings from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of asphalt millings is given in kg/m³ and the volume is in m³, the result will be in kilograms.
