Introduction to Tarmac Laying
Tarmac laying, otherwise known as tarmacking or asphalt paving, remains one of the most popular methods of giving a hard, smooth, and durable solution for driveways and roads. From resurfacing the driveway to building a new car park and right down to pathways, tarmac provides an effective solution that does not require high maintenance.
This article shows the detailed guide for laying tarmac right from preparation to maintenance.
What is Tarmac?
Tarmacadam, also known as tarmac, is a type of road surfacing material made from the combination of crushed stones and tar. It gets laid on the ground, giving it a solid and evenly matched finish. It offers really good durability and lower maintenance; hence, tarmac would be a preferable option for driveways, roads, and pathways in residences, commercials, and public places.
Benefits of Tarmac Laying
Durability and Strength: Tarmac is very durable and can easily withstand heavy traffic and extreme weather conditions. Hence, it is ideal for use in high-traffic-volume areas.
Cost-Effectiveness: Compared to other surfacing options, like concrete and block paving, the cost of tarmac is low. Considering its price, it is of high quality and therefore preferred by both homeowners and major developers.
Quick Installation: The major advantages of tarmac include that it can be laid down rather quickly. It is often used in projects which require quick completion on account of less drying time and ease in application.
Low Maintenance: Tarmac surfaces are relatively easy to maintain. Minor cracks are pretty easy to repair, as is re-surfacing tarmac driveways, thus ensuring the longevity of the surface.
Step-by-Step Process of Tarmac Laying
1. Planning and Preparation
Proper planning precedes tarmacking. This involves the identification of the area to be surfaced, followed by measurement of the area and computation of the volumes of tarmac material to be used. The site should be cleared of all obstacles and vegetation on it. Removal of debris facilitates the attainment of a smooth and level base of the tarmac.
2. Excavation and Base Preparation
After marking, the next procedure is excavation. The ground is dug to a certain depth to commence the work of laying a solid foundation; a layer of crushed stones or gravel is then laid on the ground for proper drainage and bonding of the tarmac. The base is compacted using a roller to stable it for laying tarmac on it.
3. Laying the Tarmac
Actual laying of tarmac involves spreading a layer of hot tarmac over the already prepared base. Two layers are normally applied: a binder layer and a surface layer. The binder layer provides the stability, while the surface layer gives the tarmac a smooth and polished appearance. The tarmac is laid even and rolled with a roller for an even surface.
4. Compaction
Compaction is crucial in the tarmac laying process. A mechanical roller is used to compact the tarmac, ensuring that there are no air pockets. Compacting the tarmac properly prevents cracks from forming, resulting in a strong and durable surface.
5. Curing and Finishing
The tarmac, after compaction, needs to cool and harden; this process is called curing and might take some time, from 24 to 48 hours, depending on the weather conditions. During this period of time, it should not be used at all, nor tampered with.
When it is finally cured, it is ready to use and the result is smooth and reliable.
Common Applications for Tarmac
Driveways: Tarmac is a popular choice for residential driveways due to its affordability and easy maintenance.
Roads: Many public and private roads are paved using tarmac because it is durable and can handle heavy traffic.
Pathways and Pavements: Tarmac is ideal for pathways as it creates an even surface that is comfortable for pedestrians.
Parking Lots: Tarmac's ability to handle multiple vehicles makes it a great option for car parks and commercial spaces.
Tarmac vs. Asphalt: Are They the Same?
While the terms 'tarmac' and 'asphalt' are often used together, there is, in fact, a difference. Tarmac uses tar as a binding agent, whereas asphalt uses bitumen. Keeping this in perspective, asphalt, therefore, has the advantage of performing better in high temperatures and can be smoother. Tarmac, however, normally proves less expensive than its counterpart (depending on factors like location and project size.) and more suited for minor projects, like a driveway or pavement.
Tips for Maintaining a Tarmac Driveway
Regular cleaning: can be carried out every couple of months to keep the tarmac surface clean. The dirt, leaves, and other debris should be cleared off the surface so that moss or algae does not build up on it.
Sealcoating: Sealing coat applied on your tarmac surface extends its life. Seal coating protects from water damage and maintains the freshness of the tarmac surface.
Prompt Repair of Cracks: Any small crack or hole that you notice should be repaired immediately. Regarding this, timely repairs prolong the functional life of tarmacs while maintaining the surface smooth.
Conclusion
Tarmac laying is a practical and realistic choice to develop functional, strong, resistant, and less-maintenance surfaces. Its versatility allows it to meet various needs: from light residential driveways to extensive industrial car parks. A tarmac surface can provide many years of satisfactory service, provided planning, installation, and maintenance are well executed.
