Tarmac Calculator Online
Welcome to our tarmac calculator. Accurately estimate the volume (cubic feet, cubic yards, or cubic meters) and weight (tons or tonnes) of tarmac needed for roadways, driveways, and parking lot projects. Our tool uses the standard density of conventional hot mix asphalt for precise calculations.

How to Use the Tarmac Calculator
Estimating the amount of tarmac, also known as asphalt or bitumen, is crucial for precise project planning. Use our tarmac calculator to simplify this process:
- Input your project dimensions: width, length, and thickness.
- Use the standard density of tarmac, 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 Tarmac and Asphalt
Understanding the different types of tarmac and asphalt is crucial for choosing the right material for your project. The differences primarily arise from the temperature used during the mixing process.
Tarmac Varieties
| Type | Description |
|---|---|
| Hot Mix Asphalt | Commonly used for various traffic conditions, it is known as "Dense-Graded Mix." |
| Warm Mix Asphalt | Produced at lower temperatures, suitable for off-season and night works. |
| Driveway Mix Asphalt | A cost-effective mix for driveways and parking areas, includes crushed stone, sand, and gravel. |
| Porous Asphalt | Allows water to permeate, reducing drainage needs. |
The tarmac calculator defaults to an average density of 2322 kg/m³. If your density requirements differ significantly, use the appropriate specification.
Tarmac Maintenance and Longevity
Proper maintenance is crucial for maximizing the lifespan of your tarmac surface. Regular care can prevent costly repairs and extend the life of your pavement.
Essential Maintenance Practices
- Regular Cleaning: Remove debris and clean surface regularly
- Crack Sealing: Address small cracks before they expand
- Surface Treatments: Apply sealcoating every 2-3 years
- Drainage Maintenance: Ensure proper water drainage
- Winter Care: Proper snow and ice removal techniques
Professional Tarmac Installation Guide
Quality installation is essential for durable tarmac surfaces. Follow these professional guidelines:
- Site Assessment: Evaluate ground conditions and drainage
- Base Preparation: Proper sub-base material and compaction
- Edge Support: Install proper edging and containment
- Material Selection: Choose appropriate tarmac mix
- Weather Conditions: Install in suitable weather
Tarmac vs Alternative Materials
| Material | Advantages | Disadvantages |
|---|---|---|
| Tarmac |
- Cost-effective - Quick installation - Easy repairs |
- Regular maintenance needed - Temperature sensitive - Oil susceptible |
| Concrete |
- Long lifespan - Low maintenance - High durability |
- Higher initial cost - Longer curing time - Difficult repairs |
| Block Paving |
- Aesthetic appeal - Easy repairs - Permeable options |
- Higher cost - Time-consuming installation - Weed growth between blocks |
Environmental Considerations
Modern tarmac installation must consider environmental impact. Key considerations include:
- Recycled Materials: Use of recycled tarmac in new installations
- Water Management: Proper drainage and runoff control
- Temperature Impact: Heat island effect mitigation
- Emissions Control: Low-emission installation methods
- Sustainable Practices: Eco-friendly maintenance techniques

Frequently Asked Questions
How long does tarmac take to cure?
Tarmac typically takes 24-48 hours to cure sufficiently for light traffic, but full curing may take up to 30 days. Weather conditions can affect curing time.
What is the lifespan of a tarmac surface?
With proper maintenance, a tarmac surface can last 15-20 years. Regular maintenance and timely repairs can extend this lifespan significantly.
Can tarmac be laid over existing surfaces?
Yes, tarmac can be laid over existing surfaces if they are stable and properly prepared. However, the condition of the base surface will affect the final result.
