The street surface shall be permanently restored twelve inches beyond
the excavation on all sides by milling the surface surrounding the
excavation to a depth of two inches to extend the surface course restoration.
The permanent restoration shall consist of a minimum of six inches
of dense graded aggregate, four inches of bituminous stabilized base
course and two inches of FABC-1 surface course applied with appropriate
tack coat to the adjacent pavement surface or a pavement cross section
consistent to the existing pavement section.
