Black paving material (3)
I believe the answer is:
tar
'black paving material' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tar that I've seen before include "one may need to pay on deck" , "Informal sailor or road surfacing material" , "Old salt or liquid from coal" , "Sticky cigarette residue" , "Sailor - laid on road" .)
