Bitumen Calculator Online
Welcome to our bitumen calculator. Accurately estimate the volume (cubic feet, cubic yards, or cubic meters) and weight (tons or tonnes) of bitumen needed for roadways, driveways, and construction projects. Our tool uses the standard density of conventional hot mix asphalt to ensure precision.

How to Use the Bitumen Calculator
Estimating the correct amount of bitumen, also known as asphalt or tarmac, is essential for successful project planning. Utilize our bitumen calculator to simplify this task:
- Input your project dimensions: width, length, and thickness.
- Use the standard density of bitumen, approximately 145 lbs/ft³ (2322 kg/m³) for calculations.
- Multiply the volume by the density to determine the required weight for your project.
Types of Bitumen and Asphalt
Knowing the different varieties of bitumen and asphalt is crucial for selecting the right material for your project. Key differences are due to the temperature during the mixing process.
Bitumen Varieties
| Type | Description |
|---|---|
| Hot Mix Asphalt | Highly used in various traffic conditions, known for its durability. |
| Warm Mix Asphalt | Ideal for use in cooler temperatures and overnight works due to its lower production temperature. |
| Cold Mix Asphalt | Used for minor repairs or as a patching material in low-traffic areas. |
| Porous Asphalt | Allows water permeability, helping reduce drainage requirements. |
The bitumen calculator defaults to an average density of 2322 kg/m³. Adjust your calculations based on specific density requirements as necessary.
Bitumen Grades and Applications
Understanding different bitumen grades is crucial for selecting the right material for your project. Here are the common grades and their applications:
| Grade | Properties | Applications |
|---|---|---|
| 40/50 | High stability, low temperature susceptibility | Heavy traffic roads, airport runways |
| 60/70 | Good balance of properties | General road construction, highways |
| 80/100 | Higher flexibility | Low traffic roads, cold regions |
Bitumen Maintenance and Care
Proper maintenance is essential for maximizing the lifespan of bitumen surfaces. Follow these guidelines:
Maintenance Schedule
- Daily: Remove debris and inspect for damage
- Monthly: Check for cracks and water pooling
- Annually: Professional inspection and repairs
- Every 2-3 Years: Sealcoating application
- Every 5-7 Years: Major maintenance assessment
Quality Control in Bitumen Projects
Ensuring quality in bitumen construction requires attention to several key factors:
- Material Testing:
- Penetration test
- Softening point test
- Ductility test
- Flash point test
- Temperature Control:
- Mixing temperature
- Laying temperature
- Compaction temperature
- Construction Process:
- Base preparation
- Material spreading
- Compaction methods
Environmental Impact and Sustainability
Modern bitumen construction must consider environmental factors:
- Recycling: Use of reclaimed asphalt pavement (RAP)
- Emissions: Low-temperature mixing techniques
- Water Management: Proper drainage systems
- Energy Efficiency: Warm mix technologies
- Waste Reduction: Material reuse strategies

Frequently Asked Questions
What is the difference between bitumen and asphalt?
Bitumen is the black or dark-colored binding material used in asphalt. Asphalt is the mixture of bitumen with aggregate materials used for road construction.
How long does bitumen last?
With proper maintenance, bitumen surfaces can last 15-20 years. Factors affecting longevity include traffic load, weather conditions, and maintenance quality.
What weather conditions are best for bitumen laying?
Ideal conditions include dry weather with temperatures between 50°F and 90°F (10°C - 32°C). Avoid installation during rain or extreme temperatures.
