I'm afraid that doesn't seem to be correct.
"Tarmac (short for tarmacadam) is a road surface material patented in
1901 in the UK. ... It’s essentially crushed rock mixed with cement
then sealed with tar. By today’s standards, it’s a very crude surface
and could never handle a heavy aircraft. Tarmac has not been used as
an airport surface material for decades."
Perhaps you are thinking of asphalt concrete, the substance which is
also frequently (if inexactly) called "tarmac." That substance is in
fact used on various airport aprons, not to mention many roads.
