Section 14 – Restoration of Surfaces

The edges of the existing pavement shall be given a tack coat of asphaltic emulsion. The

trench shall then be filled and compacted, in layers not to exceed two inches (2”), with asphalt

concrete, Type "A", conforming to Section 23, “Asphalt Concrete”, of these Specifications until

the trench has been brought to approximately three-quarter inch (3/4”) below the finish grade

and cross section of the street. The Contractor shall immediately repair any settlement more

than one inch (1”) below finish grade.

Prior to placement of the second lift, the surface of the first lift of pavement and the edges of

the existing pavement shall be given a tack coat of asphaltic emulsion. The trench shall then be

filled and compacted with asphalt concrete Type "A", one-half inch (1/2”) maximum gradation,

as specified above, until the pavement has been brought to the final grade and cross section of

Unless otherwise noted, a single seal coat (see Section 14-3.03.A) shall be applied after

placement of the final lift of asphalt concrete.

Final pavement surface for trenches greater than three feet (3’) in width that are mostly

parallel to the centerline of the street shall not vary from the edge of a 10-foot straight edge

(placed parallel and perpendicular to the trench) by more than 3/8-inch, except at intersections

or changes in grade.

Final pavement surface for trenches three feet (3’) or less in width, bore holes having an

area less than fifty (50) square feet, and trenches of any width that are not mostly parallel to the

centerline of the street shall match the smoothness of the existing pavement, except final

pavement surface grade shall not exceed three-eighths of an inch (3/8”) above a line between

the existing pavement surface at each edge of the excavation. Final pavement below this line is

Pavement not meeting the above requirements shall be removed and replaced to a

minimum depth of one and one-half inches (1-1/2”) for the full width of the trench. The minimum

length of removal along the trench shall extend to four feet (4’) beyond the ends of the non-

conforming areas, but in no case shall the removal and replacement exceed the limits of the

original excavation.

Density of compacted asphalt concrete may be tested at the discretion of the inspector.

Core samples taken for testing compaction of asphalt concrete shall be tested in accordance

with ASTM D2726-89 and shall be ninety-two percent (92%) or greater of the maximum

Theoretical Density as determined by ASTM D-2041 (based on the full depth of the asphalt

Seal coat treatment shall be applied at locations specified, as shown on the Plans or as

directed by the Agency. Seal coat shall not be placed until at least seventy-two (72) hours after

placement of the final paving lift.

14-3.03.A Single Seal

Alternate 1 - Slurry seal shall be furnished and placed as specified in Section 37-2,

“Slurry Seal”, of the State Specifications, with the exception that the fifth paragraph

of Section 37-2.06, "Placing", shall be modified to provide that the thickness of

application of slurry seal shall be adjusted to provide one (1) layer not less than one-

eighth inch (1/8”) thick nor greater than one-quarter inch (1/4”) thick. The

requirement for wetting surface prior to placement of slurry seal is waived.

Alternate 2 - Sand seal shall be furnished and placed as specified in Section 37-1, "Seal

Coats”, of the State Specifications with the exception of the requirements for the

asphaltic binder and aggregate. Asphaltic binder and aggregate shall be as follows:

The asphaltic materials for the construction of sand seal shall conform to the

requirements in Section 50-17, “Asphalt, Liquid Asphalt, and Asphaltic

Emulsion”, of these Specifications. The asphaltic materials shall be CRS 1.
