Job conditions.
(1) 
Control of traffic.
(a) 
Take measures to control traffic during paving operations. Do not allow traffic on newly paved areas until adequate stability and adhesion have been attained and the material has cooled to 140° F. or less.
(b) 
Employ traffic control measures in accordance with Publication 203.
(2) 
Protection of adjacent areas. Restore existing surface outside the limits of the work, that has been damaged by the contractor's operations, to its original condition at the expense of contractor.
(3) 
Concrete testing: See Article XXVII.
A. 
Concrete.
(1) 
As specified in Article XXVII.
(2) 
For driveway restoration, use air-entrained, PennDOT Class HES (high early strength). (Three-day compressive strength of 3,000 psi, twenty-eight-day compressive strength of 3,750 psi, as per Section 704 of Pub. 408).
B. 
Bituminous materials and aggregates. All bituminous materials and aggregates used in base course construction, paving, and resurfacing are designated in these specifications by, and shall conform to, the applicable portions of the Publication 408 Specifications. See descriptions in Articles VIII and XI.
A. 
Temporary trench paving.
(1) 
Place temporary paving immediately upon completion of trench backfilling. Unpaved trenches shall not remain unpaved longer than five working days after backfilling, nor over weekends and holidays.
(2) 
Shape and compact subgrade material, then place and compact base course to the required thickness.
(3) 
Place temporary paving material. Compact to required minimum thickness with trench roller having a minimum 300 pounds pressure per inch-width of compaction.
(4) 
Continuously maintain temporary paving.
B. 
Permanent trench paving.
(1) 
For bituminous surface course (trench), saw cut existing paving in accordance with Publication RR-459. Remove temporary paving material.
(2) 
Construct permanent base and surface courses to the required compacted thicknesses shown in the Backfill and Surface Restoration Requirements Table,[1] and in accordance with Publication 408 Specifications. In state highways, construct permanent paving in accordance with highway occupancy permit requirements.

Editor's Note: Said table is included as an attachment to this chapter.
(3) 
Maintain permanent paving throughout the contract maintenance period.
C. 
Bituminous overlay: see Article XI.
D. 
Shoulder restoration. Restore shoulders as directed by the municipality. In state highways, restore in accordance with highway occupancy permit requirements.
E. 
Driveways.
(1) 
Trim concrete and bituminous driveway surfaces to remove damaged areas. Saw or cut straight joint lines parallel to the center line of the trench. Cut offsets at right angles to the trench center line.
(2) 
Restore existing concrete driveways with a six-inch layer of concrete reinforced with WWF 6 x 6 - W2.9 x W2.9 (6 ga.) wire mesh, placed two inches from top surface. See Article XXVII.
(3) 
Restore existing bituminous driveways in kind; minimum one-and-one-half-inch layer wearing course over six-inch layer of select granular material (2RC).
(4) 
Restore earth driveways with a six-inch layer of select granular material (2RC).
(5) 
Restore stone or gravel driveways in kind; minimum six-inch layer of select granular material (2RC).
(6) 
Restore brick driveways with like bricks placed on a four-inch thick wet sand bed. Place bricks in like pattern and spacing.
