The amount of coverage you can expect from 1 ton of tarmac for your driveway depends on several factors. According to the first source, Aggregate Industries, their asphalt calculator can help you determine the tonnage of asphalt you will need for your project. It takes into account the type of asphalt, as well as the width, height, and depth of the area you want to cover.
The calculator also factors in a minimum level of required asphalt to avoid wastage, and it’s recommended to allow for a 5% margin to cover additional needs. The calculator provides an estimate of the asphalt required in tonnes. Additionally, the second source provides a comprehensive guide on how to calculate the quantity of asphalt needed. It explains that you need to know the length, breadth, and depth of the area you want to cover.
By multiplying the length and breadth, you get the square footage, and then multiplying this by the depth gives you the cubic feet of asphalt required. The density of the asphalt can vary, but a common density used in calculations is 2.4 tonnes per cubic meter. By multiplying the cubic meters by the density, you can determine the number of tonnes of asphalt needed. It’s important to note that asphalt comes in batches of 1 tonne, so you may need to purchase more than 1 tonne to cover your entire driveway.
Stay tuned for the next section where we’ll discuss the factors that can affect the coverage of a tarmac driveway.
Factors Affecting Tarmac Driveway Coverage
When planning tarmac driveway projects, it’s essential to consider various factors that can affect the coverage achieved with 1 ton of tarmac.
These factors include the size and shape of the driveway, the condition of the existing surface, the desired thickness of the asphalt layer, and the preparation work involved.
Additionally, regular maintenance and sealing can play a role in prolonging the lifespan of the driveway and reducing the need for additional asphalt in the future.

The size and shape of the driveway are key factors in determining the amount of tarmac needed. Larger driveways will naturally require more asphalt to cover the entire area compared to smaller driveways. Additionally, irregularly shaped driveways may have more complex dimensions that affect the coverage calculation.
If you’re planning to resurface an existing driveway, the condition of the current surface will impact the coverage. Deep cracks or potholes may need repair before applying the new tarmac, requiring additional asphalt to fill these areas. It’s important to assess the condition of the driveway and address any necessary repairs beforehand.
Another factor to consider is the desired thickness of the asphalt layer. A thicker layer will require more asphalt, providing a more durable surface for heavier traffic loads. Conversely, a thinner layer may be suitable for lighter traffic areas but will provide less coverage with 1 ton of tarmac.
Furthermore, preparing the site for tarmac installation can influence the amount of asphalt needed. Excavation and leveling work may be required to create a smooth and even surface for the tarmac. These additional steps can affect the overall coverage calculation.
In addition to these factors, regular maintenance and sealing of the tarmac driveway can significantly extend its lifespan. Proper maintenance practices, such as regular cleaning, crack repairs, and sealing, can help prevent damage and weathering, reducing the need for additional asphalt in the future. By taking these factors into account, you can ensure optimal coverage and durability for your tarmac driveway.
Choosing the Right Type of Tarmac for Your Driveway
When it comes to creating a durable and visually appealing tarmac driveway, choosing the right type of material is essential. Asphalt is the preferred choice for many homeowners due to its smoother finish and quieter driving experience compared to traditional tarmac. Additionally, asphalt offers a range of options, including colored asphalts, that can enhance the overall aesthetic of your driveway.
It’s recommended to consult with professional driveway contractors who have expertise in tarmac driveways. They can provide valuable advice on the best materials and techniques for your specific project. These contractors can guide you through the selection process, taking into account factors like durability, weather resistance, and cost-effectiveness.
Furthermore, sealing your tarmac driveway is crucial for long-term protection against cracks, damage, and weathering. Regular maintenance and sealing can significantly extend the lifespan of your driveway, reducing the need for costly repairs in the future. Driveway sealing can also help maintain the color of colored asphalts and enhance their appearance.
Table: Types of Asphalt Materials
| Type of Asphalt | Recommended Use |
|---|---|
| Standard Asphalt | Residential road surfacing |
| Colored Asphalt | Enhanced aesthetics for driveways, car parks |
| Industrial Estate Asphalt | Durable surfacing for industrial estate roads |
