To be precise, "tarmac" is not used much any more, the correct terminology being "coated macadam" or "asphalt paving". This is because tar, being a by product of the coking industry, is no longer produced in this country. Today's road making material has no tar in it, the binder or cement used to "bind" the aggregates together being bitumen which is a naturally occurring material like oil, coal or pitch.
Most bitumen used in this country is imported from Venezuela.
However, tarmac used to be used on the hard shoulders of motorways because fuel is more likely to be spilled when a lorry or car stops on the hard shoulder and the tar is less soluble than bitumen in diesel fuel. For the same reason, airport aprons are usually constructed using concrete rather than materials containing bitumen.
In conclusion, I find no reason for tarmac to exist in today's society and have therefore voted accordingly
