From Dusty to Dazzling: The Art of Tarmac Driveway Construction and Maintenance

A well-constructed and well-maintained driveway not only provides a smooth and durable surface for vehicles but also enhances the curb appeal of your home. Among the various types of driveways, tarmac driveways have gained immense popularity due to their affordability, versatility, and long-lasting nature.

This article delves into the art of tarmac driveway construction and maintenance, highlighting the key aspects that contribute to transforming a dusty patch of land into a dazzling entrance that says “Welcome”.

Stage 1: Construction

Constructing a tarmac driveway requires careful planning, meticulous preparation, and precise execution. Let’s analyse briefly the primary steps involved in the process:

• Site Preparation: Before any construction begins, the area designated for the driveway needs to be cleared of any vegetation or debris. Your tarmac contractor will then dig out the soil to a depth of about 20 cm and fill it with a layer of crushed stone that is compacted with a roller. This is necessary to address any underlying issues, such as poor soil stability, and it ensures a level base for proper drainage. 

• Edge Restraints: To maintain the structural integrity of your driveway, you have to install sturdy edge restraints along the perimeter. These can be made of concrete or brick materials and prevent the edges from crumbling or spreading over time.

• Binder Course: Following the restraints, your contractor will apply a binder course on the bottom layer. This layer consists of coarse aggregate mixed with bitumen or tar, creating a strong bond between the base and the surface layer.

• Surface Layer: The final layer, also known as the wearing course, is where the tarmac driveway truly shines. Your contractor will spread a mixture of fine aggregate, bitumen, and additives evenly over the binder course and use specialised machinery to compact the surface layer, ensuring a smooth and uniform finish.

Stage 2: Maintenance

To preserve the beauty and functionality of a tarmac driveway, it is essential you maintain it regularly. Here are some key maintenance practices to keep in mind:

• Cleaning: No, any ordinary broom won’t do. Buy a power washing machine or contract a lawn service to remove dirt, leaves, and debris that may accumulate on the surface of your tarmac over time. This prevents weed growth and maintains the appearance of the driveway.

• Sealing: Due to environmental conditions, the tar used to hold tarmac aggregates together can degrade over time. To provide a protective barrier that helps prevent water penetration, cracking, and fading caused by sunlight, reapply a sealant every few years.

• Repairing Cracks: Over time, small cracks may appear due to changes in temperature or heavy vehicle traffic. You can fix these cracks with a suitable crack filler, preventing further deterioration and extending the life of the driveway.

• Preventing Damage: Try as much as possible to avoid using harsh chemicals, such as de-icing salts, on the driveway surface. These substances can damage the tarmac and lead to premature wear and tear. Also, avoid parking heavy vehicles or machinery on the tarmac for extended periods in the same to prevent surface depressions.

• Regular Inspections: Conducting regular inspections allows you identificatory any emerging issues, such as potholes or drainage problems. This gives you time to repair it timely, saving you money in the long run by preventing larger-scale damage.

Conclusion

Tarmac driveway construction and maintenance requires a combination of skill, precision, and regular care. Adopting proper construction techniques and diligent maintenance practices will immensely contribute to transforming any dusty plot into a curb to die for.
