Snake stopping on paving (10)

I believe the answer is:

asphalting

'paving' is the definition.
(asphalting is a kind of paving)

'snake stopping on' is the wordplay.
'snake' becomes 'asp' (asp is a kind of snake).
'stopping' becomes 'halting' (halting is a kind of stopping).
'on' is a charade indicator (letters next to each other).
'asp'+'halting'='ASPHALTING'

I've seen this clue in the Sydney Morning Herald.
