What Is Tarmac Surfacing? Everything You Need to Know

When it comes to surfacing solutions in the UK, tarmac remains a firm favourite for driveways, roads, car parks, and more. Renowned for its durability, cost-effectiveness, and relatively quick installation, tarmac offers a practical and visually appealing surface that stands the test of time. But what exactly is tarmac surfacing, and is it the right choice for your project?

Kane Construction serves Surrey and London with decades of experience, and are experts in all things tarmac. 

This comprehensive guide will delve into everything you need to know about tarmac surfacing, from its composition and benefits to the installation process and maintenance tips. Whether you’re a homeowner, a business owner, or a property manager, this information will equip you with the knowledge to make informed decisions and achieve a tarmac surface that meets your specific needs.

What is Tarmac? Unpacking the Composition of This Popular Surface

Tarmac, short for tarmacadam, is a composite material primarily used for surfacing roads, driveways, and other outdoor areas. It’s composed of:

• Aggregate: Crushed stone, gravel, or slag that provides the bulk and structural integrity of the material. The type and size of aggregate used can influence the texture and appearance of the finished surface.
• Bitumen: A black, sticky, and highly viscous liquid or semi-solid form of petroleum. Bitumen acts as the binder, holding the aggregate particles together and providing the flexible and waterproof characteristics of tarmac.
• Other Additives: Depending on the specific application and desired properties, tarmac may contain other additives, such as polymers, fibres, or pigments, to enhance its performance, durability, or aesthetic appeal.

The mixture of these materials is heated and then laid and compacted to form a solid, durable surface.

The Benefits of Tarmac Surfacing: Why Choose Tarmac for Your Project?

Tarmac surfacing offers a wide range of benefits, making it a popular choice for various applications:

• Durability: Tarmac is highly resistant to wear and tear, weathering, and traffic, making it ideal for high-use areas.
• Cost-Effectiveness: Compared to other surfacing materials, such as block paving or resin-bound gravel, tarmac is often a more cost-effective option, both in terms of initial installation and long-term maintenance. At Kane Construction, we pride ourselves on offering cost-effective quotes that are as efficient as possible.
• Quick Installation: Tarmac can be laid and compacted relatively quickly, minimising disruption to your property or business operations. As showcased in our Aldershot project, tarmac surfacing can be completed within just 3 days, and without workflow disruption.
• Smooth and Even Surface: When properly installed, tarmac provides a smooth and even surface, making it suitable for vehicles, pedestrians, and cyclists.
• Weather Resistance: Tarmac is resistant to water damage, frost, and other weather conditions, making it a reliable surfacing solution in the UK climate.
• Easy Maintenance: Tarmac requires minimal maintenance. Occasional cleaning and crack repairs are typically sufficient to keep it in good condition.
• Versatility: Tarmac can be used for a wide range of applications, including driveways, roads, car parks, footpaths, playgrounds, and more.
• Customisation: While often associated with a black finish, tarmac can be coloured using pigments to create different aesthetic effects. Additionally, decorative edgings can be added for a more visually appealing result.
  *Pothole Repair friendly: As we understand the detrimental effects of unsightly potholes on roads and car parks, tarmac makes it easy for us to effectively repair potholes and restore the surface to its original condition, with cutting-edge techniques and high-quality materials for long-lasting and reliable repairs.

The Tarmac Surfacing Process: From Preparation to Completion

The tarmac surfacing process typically involves the following steps:

1. Site Survey and Planning:
   • A qualified surveyor will assess the site to determine the existing ground conditions, drainage requirements, and any potential obstacles.
   • Based on the site survey, a detailed plan will be developed outlining the scope of work, the materials to be used, and the project timeline.
2. Preparation:
   • The site will be cleared of all vegetation, debris, and any existing surfacing materials.
   • The subgrade (the layer of soil or aggregate beneath the surface) will be prepared to ensure a stable and level base for the tarmac. This may involve excavation, compaction, or the addition of a subbase layer.
3. Laying the Tarmac:
   • Hot asphalt is delivered to the site in specialised trucks.
   • The asphalt is spread evenly over the prepared base using paving equipment.
   • The asphalt is compacted using heavy rollers to create a smooth, dense, and durable surface.
4. Finishing:
   • The edges of the tarmac surface are carefully trimmed and finished to create a clean and defined edge.
   • Any necessary drainage adjustments are made.
   • Line markings (e.g., parking spaces) are applied if required.
5. Curing:
   • The tarmac surface is left to cool and cure for a specified period (typically 24-48 hours) before it can be used.

Types of Tarmac Surfacing:

Different types of tarmac are available, each suited for specific applications:

• Dense Bitumen Macadam (DBM): A general-purpose tarmac suitable for roads, driveways, and car parks.
• Hot Rolled Asphalt (HRA): A durable and smooth tarmac ideal for high-traffic areas, such as major roads and airport runways.
• Stone Mastic Asphalt (SMA): A highly durable and rut-resistant tarmac used for heavily trafficked roads and industrial areas.
• Asphalt Concrete: A mixture of asphalt and fine aggregate, used for smoother surfaces such as driveways or pathways.

Maintaining Your Tarmac Surface: Ensuring Longevity and Performance

Proper maintenance is essential for extending the lifespan of your tarmac surface:

• Regular Cleaning: Sweep or hose down the surface regularly to remove dirt, debris, and vegetation.
• Crack Repair: Repair any cracks or potholes promptly to prevent water damage and further deterioration.
• Seal Coating: Consider applying a seal coat every few years to protect the tarmac from weathering, UV damage, and oil spills. A fresh overlay layer can breathe new life into existing tarmac or concrete driveways – saving money and minimising workflow disruption.
• Avoid Heavy Loads: Avoid driving heavy vehicles or placing heavy objects on the tarmac surface, as this can cause damage.
• Address Drainage Issues: Ensure that the drainage system is functioning properly to prevent water from pooling on the surface.

Tarmac Repairs: Restoring Damaged Surfaces

Over time, tarmac surfaces can develop cracks, potholes, or other forms of damage. Prompt and effective repairs are essential for preventing further deterioration and maintaining the safety and appearance of the surface.

• Pothole Repair: Potholes can be repaired by filling them with a cold-mix asphalt patching compound or by using a hot-mix asphalt repair method.
• Crack Sealing: Cracks can be sealed with a flexible crack sealant to prevent water from penetrating the surface.
• Overlaying: Severely damaged tarmac surfaces can be overlaid with a new layer of tarmac to restore their integrity and appearance.

Is Tarmac Surfacing Right for You? Factors to Consider

When deciding whether tarmac surfacing is the right choice for your project, consider the following factors:

• Budget: Tarmac is generally a cost-effective surfacing option, but it’s important to obtain multiple quotes and compare prices.
• Traffic Volume: Tarmac is well-suited for areas with moderate to heavy traffic.
• Aesthetic Preferences: While tarmac is often associated with a black finish, it can be customised with different colours and edgings to suit your aesthetic preferences.
• Maintenance Requirements: Tarmac requires minimal maintenance, but regular cleaning and crack repairs are necessary.
• Environmental Considerations: Consider the environmental impact of tarmac and explore sustainable alternatives, if appropriate.
