Tarmac is an oil-based product; the binder is a heavy tar or bitumen and as such, it can be 'thinned' by the addition of a lighter oil, such as paraffin, petrol or even turpentine. Many automotive oils, such as petrol, diesel or even brake fluid, can 'dissolve' the binder of a tarmac and there's no way of 're-sticking' the aggregate back together. Further, the contaminating oil will seep and spread, degrading all the tarmac that it contacts. Given a few days, a petrol leak will 'eat' its way through a 75mm thick tarmac driveway; a screwdriver or stiletto heel will easily penetrate the previously 'set' surfacing and before long, the now unbound aggregate will begin to be scattered everywhere. And once a hjole appears in a tarmac surface, it just gets bigger and bigger as the edges 'crumble'.
A tire risks melting when making contact with surfaces over 250 degrees.
Yes, if the pavement is hot enough. They are normally fine, but don't wear them to Volcanoes National Park in Hawaii.
Tarmac is not a rock, but a man-made road surfacing material.

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
When installed, tarmac is a mixture of solid aggregate in liquid asphalt. When the mixture cools, the finished tarmac pavement is solid.
Yes but the nobbly tyres don't grip on tarmac in the wet.
The materials used in auto track pavement include cement and asphalt. Tarmac is sometimes used as well or stones to place on top of the surface and give a nice finish.
Tarmac appears darker when wet because the water fills the pores in the surface, reducing the reflection of light. The water on the surface creates a smooth layer that decreases light scattering, making the pavement appear darker.

Not usually, no. The "ramp" or "apron" is the part of the airport where airplanes park to load or unload. "Tarmac" is a more generic term referring to any paved part of the airport. It may be used to refer to the ramp, the taxiways, the runways, or indeed even when referring to the pavement itself in a more general sense.
Tarmac Limited's population is 12,500.
Tarmac Limited was created in 1903.
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.
