Are we talking about a tarmac car park surface edged with kerbstones
and grass growing in the "groove" between the two (and maybe between
the kerbstones)? If so, the best approach is probably a weed burner
(the instructions will say something like singe the top growth but
give the grass a longer shot). Councils and licenced landscapers will
have access to stronger chemicals than you. Few "domestic" products
will be effective in this situation.

Then check the surface and if it's worthwhile, buy a bag of drive
patch stuff from somewhere like Wickes and tamp it well into the gaps
between tarmac and kerbs.
