(A) Improved streets. On improved streets, a temporary pavement consisting of bituminous cold patch material, not less than three-inch compacted depth shall be installed flush with the surface of the existing undisturbed pavement and shall be maintained until permanent restoration has been completed. On unimproved streets, compacted 2-A stone material, not less than three inches compacted depth shall be installed and maintained until permanent restoration has been completed.
(B) Streets or alleys. On streets or alleys that have been improved within a period of five years or less from the date of the utility disturbance, the contractor shall be required to mill the existing pavement surface between the outside edges of pavement (curb line to curb line) of the existing pavement and to a point not less than two feet beyond the limits of the opening. Trench restoration shall be the same as that described for bituminous pavement, excepting that the entire area shall receive a one and one-half- inch compacted depth overlay of Superpave 9.5 mm wearing material.
(C) Permanent restoration.
(1) Permanent restoration shall be performed and completed as soon thereafter as the utility work has been completed, but in no instance shall permanent restoration be completed any longer than three months from the official date of said completion, except as may be necessitated by winter weather conditions and as approved by the borough. Failure to comply shall result in the penalties as set forth elsewhere herein.
(2) Permanent restoration shall meet the following requirements:
(a) 1. Bitumous pavement restoration shall consist of the following: saw one foot outside the initial excavation and remove temporary paving and base to a depth of seven and one-half inches below the existing finished surface and furnish and install as follows:
a. Thoroughly compact the sub-grade;
b. Place three-inch compacted depth of a 2-A modified stone base;
c. Place three-inch compacted depth of 19.0 mm Superpave binder material;
d. Place one and one-half inch compact depth of 9.5 mm Superpave wearing material; and
e. Immediately following paving operations hand mop and seal all edges where new pavement meets existing surfaces with AC-20 sealing material.
2. When four or greater consecutive openings occur at one time (within a 12- consecutive month period) within one-half of any street (from the centerline to the outside edge of pavement (curb line), the contractor shall be required to perform the following additional work:
a. Mill the existing pavement surface from the centerline to the outside edge (curb line) of the existing pavement and to a point not less, than two feet beyond the limits of the farthest openings; and
b. Trench restoration shall be the same as that described for bituminous pavement, excepting that the entire area shall receive a one and one-half inch compacted depth overlay of Superpave 9.5 mm wearing material.
3. When four or greater openings occur within one block between outside edges of pavement (curb line to curb line), (within a 12-consecutive month period), the contractor shall be required to perform the following additional work:
a. Mill the existing pavement surface between the outside edges of pavement (curb line to curb line) of the existing pavement and to a point not less than two feet beyond the limits of the farthest openings; and
b. Trench restoration shall be the same as that described for bituminous pavement, excepting that the entire area shall receive a one and one-half inch compacted depth overlay of Superpave 9.5 mm wearing material.
(b) 1. Where concrete curb is to be restored, the contractor shall saw out and remove affected curb to the next undisturbed expansion or contraction joint, shall place one-half inch pre-molded expansion joint material and install medium depth 18-inch plain cement curb to match width and reveal of the adjacent existing undisturbed curb.
2. Concrete shall be 4,000 p.s.i. air entrained. All new finished concrete surfaces shall be treated with BASF Enviroseal 40 or equivalent.
(c) 1. Where concrete sidewalk is to be restored, the contractor shall excavate and remove existing affected sidewalk to the next undisturbed expansion or contraction joint shall saw cut smooth and replace full slabs. Specifications shall include a three-inch minimum depth of compacted cinders or crushed stone sub-base and five inch thickness of 4,000 p.s.i. air entrained concrete, with No. 6/6 gauge welded wire fabric one-half inch pre-molded expansion joints where new concrete construction meets existing construction and placed at 30-foot center to center, with contraction joints at ten-foot center to center. All new finished concrete surfaces shall be treated with ASF Enviroseal 40 or equivalent.
2. Additional restoration shall be required as follows.
a. If disturbed lanes adjacent to undisturbed lanes are overlaid, the edge of the disturbed lanes shall be saw cut or milled to a depth of one and one-half inches or the depth of the existing surface course, whichever is less, for the length of the opening to ensure a smooth joint, with proper elevation and cross-sections. A full width overlay may be authorized on various roadways instead of saw cutting or milling the disturbed land.
b. Restored openings in the pavement or paved shoulder shall be sealed in the case of bituminous concrete or in the case of cement concrete.
