What Is Tarmac And How Is It Used?
You have probably heard of the term “tarmac” in relation to airports. However, you may not know what it actually is.
Tarmac is a type of road surface made from crushed stones mixed with tar. It is commonly used at airports where planes taxi from the runway to the apron and back again. It is also useful to understand the process of resurfacing tarmac if you have a driveway that needs repaired.
What Is Tarmac?
Essentially, it’s crushed aggregate or stone coated with hot tar. The tar is added to the stone and sand mixture before being laid down. It is then compacted with a vibrating roller, making it durable and smooth. It is sometimes referred to as tarmacadam or bitumen.
In modern times, tarmac is typically made with asphalt concrete rather than just tar. The addition of asphalt helps to increase its strength and durability.
Tarmac is easy to lay, quick to cure and suitable for use in most weather conditions. It is also a very cost-effective material to use when laying driveways, roads or other surfaces.
How Is Tarmac Used?
While tarmac is often used in airports, it’s also very useful for driveways and other surface areas. It is a very durable material and can hold up to the weight of heavy airplanes and highway vehicles. It is also very quick and easy to install. This makes it a great option for those looking to make their driveways look nice and new.
The word tarmac actually comes from a British construction company called Tarmac Limited. The company is still in business today, but they have since expanded their operations to include other products.
Tarmac VS Asphalt
When it comes to paving your driveway or other outdoor surfaces, you have plenty of choices. Two popular options are tarmac and asphalt. While we often use the terms interchangeably, they are not the same thing. Tarmac is a mixture of tar and crushed stone that cures very quickly. It is an ideal surface material for roads, pavements and driveways because it is hard-wearing, long-lasting, and can withstand the weather conditions in your area.
Asphalt is a similar product, but it uses bitumen rather than tar. While this doesn’t seem like a big difference, it makes a significant difference when you consider the environmental impact of each material.
What Are The Benefits?
Tarmac is hard-wearing and water resistant, making it the perfect material for a driveway or road. It also has the ability to withstand various weather conditions, which makes it a great choice for those living in colder climates.
The first macadamized road was invented by John Loudon McAdam, but it wasn’t until Edgar Purnell Hooley added tar that paved the way for modern-day tarmac. This addition enhanced the existing macadam method and made it dust free. Today, tarmac is made from mineral aggregates coated with bitumen. This material is commonly used for car roads, airport runways, and parking areas.
