Paving Cost-Effective:
Tarmac is one of the most affordable paving materials, both in terms of initial installation and long-term maintenance. It’s an economical option for large surfaces like driveways, roads, and parking areas.
Quick Installation:
Tarmac can be laid quickly and efficiently, reducing the disruption caused by long construction periods. It also dries fast, meaning areas can be used soon after installation.
Durability:
Tarmac is tough and resilient, making it ideal for high-traffic areas like roads and driveways. It can withstand heavy loads, such as vehicles, without cracking or breaking easily.
Low Maintenance:
Tarmac requires minimal maintenance over its lifespan. Simple repairs like patching cracks or resurfacing can prolong its life, and the material itself is relatively resistant to weather and wear.
Smooth Surface:
Tarmac provides a smooth, even surface that is comfortable to drive or walk on. This makes it ideal for roads, pathways, and driveways, reducing the risk of tripping hazards.
Weather Resistance:
Tarmac is resistant to different weather conditions, from rain to snow and heat. It performs well in cold climates because it can flex with freeze-thaw cycles, preventing cracking.
Recyclable:
Tarmac is an environmentally friendly option because it is 100% recyclable. Old tarmac can be reheated and reused, reducing the need for new materials and minimizing waste.
Skid Resistance:
Tarmac provides good traction for vehicles, reducing the risk of skidding, especially in wet conditions. This makes it a safe choice for roads and driveways.
Disadvantages of Tarmac Paving
Limited Aesthetic Appeal:
Tarmac is mostly available in black, offering little in terms of design or visual appeal compared to more decorative materials like stone, brick, or resin-bound paving.
Maintenance Over Time:
While durable, tarmac is prone to developing cracks, potholes, and ruts over time, especially in areas with heavy use. Regular maintenance, like filling cracks and sealing, is needed to maintain its integrity.
Shorter Lifespan in Harsh Conditions:
In extreme climates, especially very hot weather, tarmac can soften, deform, or develop ruts from heavy traffic. In such cases, its lifespan may be shorter than that of more rigid materials like concrete.
Surface Water Retention:
Tarmac is not permeable, so water does not drain through it. In areas without proper drainage, surface water can pool, potentially leading to flooding or the breakdown of the tarmac surface.
Vulnerability to Oil and Chemicals:
Tarmac can be damaged by oil, gasoline, and other chemicals, which can weaken or degrade the surface over time. Driveways or parking lots where vehicles may leak fluids are particularly vulnerable.
Environmental Impact:
The production of tarmac involves the use of fossil fuels, contributing to environmental pollution. Although recyclable, its manufacturing process has a larger carbon footprint than some other materials.
Color Fading:
Over time, the color of tarmac can fade from black to a dull gray due to exposure to sunlight and the elements. This fading may require resurfacing to restore its appearance.
Susceptible to Freeze-Thaw Damage:
In colder climates, tarmac can be affected by freeze-thaw cycles. While it performs better than some materials, water that seeps into small cracks can freeze, expand, and worsen existing damage.
