Macadamized (5)
I believe the answer is:
paved
'macadamized' is the definition.
(similar in meaning)
This is the entire clue.
(Other definitions for paved that I've seen before include "Covered with slabs" , "(Ground) covered with stone or brick" , "Covered with flat stones" , "Covered with flagstones" , "Covered with a firm surface" .)
