tack coat of emulsified asphalt.
L.
All roadways shall be prepared in such a manner that all manholes,
catch basins, valve gates or other structures in a roadway are installed
with bituminous paving around the perimeter of each such structure
such that a smooth transition is maintained between the top of each
structure and the road surface.
M.
If requested by the Board, compaction and plane of finished surface
tests shall be performed on the top course paving once in place. All
