The reason airport concrete strips are referred to as tarmac is because the company that made the product was called Tar MacAdam, which was shortened to tarmac. Airports during WWII extensively used the product, and the term carried through the decades exclusively when referring to airport concrete, whether or not tarmac is actually used.
I would think the closest synonym might be "runway". Tarmac is a macadam road surface, used for streets, highways, and runways. But it is usually just in reference to airport runways you hear it referred to as "tarmac".
The 1903 trademarked name "Tarmac" derives from "tarmacadam" (1882). By 1919, generally used in Great Britain to describe a runway.
Yes, you need to know the density of tarmac which varies depending on the aggregate used but is around 2.4 tonne per cubic metre
Tarmac Limited's population is 12,500.
Tarmac Limited was created in 1903.
If we didn't have Tarmac roads the roads would be bumpy and dusty, the dust would go in to the air and cause people to cough and could cause crashes. The inventor of Tarmac is Edgar Hooley he invented Tarmac in 1902. Tarmac is heated and then poured on to road.
Tarmac, short for tarmacadam, was patented in the 19th century by Scottish engineer John Loudon McAdam. It is a road surfacing material made of crushed stone mixed with tar or bitumen, primarily used for surfacing roads and pavements.
When installed, tarmac is a mixture of solid aggregate in liquid asphalt. When the mixture cools, the finished tarmac pavement is solid.
Only if... (a) you know the weight of a measured amount of tarmac - and (b) you know what depth the tarmac is. If you can calculate the volume of tarmac, and you know the weight of a specific amount - you can convert to tonnes.
