Asphalt, also known as bitumen, is actually just a sticky binding substance, very similar to crude oil, but in a solid form. It is only when it is mixed with aggregates, such as gravel or crushed stone, that it becomes asphalt concrete or tarmac, and this is the material we commonly use when constructing roads, driveways or any area trafficked by vehicles.
Most asphalt driveway has 2″ of base pavement (lower course), followed by 1″ of wearing pavement. Open-graded asphalt concrete is mixed with course aggregates (as large as 70mm in diameter), may be permeable and is normally used for the base pavement of the driveway. Close graded asphalt concrete is normally the choice for wearing surfaces as it has a tighter-looking finish, being mixed with fine aggregates (3mm or less) and is often considered a non-permeable substance. The tarmac driveway cost will largely depend upon the look or finish of the wearing surface you choose for your driveway.
The wearing surface can also be ‘dyed’, using a coloured binder, such as coloured aggregates or coated chippings to produce a finish of the desired appearance, which of course will add to the costs for asphalt driveway.
Tarmac Driveway Cost
Although the most common colour for driveways is black, tarmac can be made in almost any colour. A ‘rusty’ red colour is also popular because the ‘quartzite’ aggregate, typically used for this colour, is known for helping the surface retain it colour depth, despite the red pigment added to the bitumen binder having faded. Other popular colours are green and blue which are often employed on sports surfaces, such as tennis and basketball courts. In addition, instead of choosing one single colour for the entire surface of your driveway, you can opt for a decorative finish, which may involve mixing larger coloured aggregates, or ‘chips’, of a contrasting colour into the tarmac.
Choosing to have a coloured or decorative driveway will significantly add the tarmac driveway cost.
Secondly, when considering asphalt driveway cost, you must bear in mind that most asphalt driveway cost is calculated by the ton. Therefore, people, who only need a small area covered, will find that tarmac driveways costs can be relatively expensive in comparison to other materials, since workers will often charge at a day rate plus costs of transporting the necessary equipment to site.
Lastly, the costs for asphalt driveway can be somewhat volatile because the key materials used in constructing them are oil based. Everyone is well aware of how often the price of oil fluctuates, and tarmac driveway cost rise and fall in a likewise manner.
