The City Engineer, at the time the permit is issued, will specify whether the base is to be replaced with cement concrete or a full depth structural bituminous concrete patch.
(1) 
Replacement with rigid cement concrete base.
(a) 
When cement concrete is to be used to replace the excavated base material, all reinforcing steel encountered when removing the cut back concrete shall not be cut off but retained and used to tie in the reinforcing in the new concrete patch. Reinforcing shall be furnished, in the area to be patched, to provide the equivalent of No. 4 reinforcing bars on twelve-inch centers, each way. Where granite block is encountered under the bituminous paving, these blocks shall be removed and the area replaced with cement concrete in accordance with the requirements of this section.
(b) 
The thickness of the concrete placed shall be a minimum of six inches or equal to the depth of the existing base, whichever is greater.

When a full depth bituminous concrete patch is to replace the excavated concrete base, the concrete base shall be cut back minimum of 12 inches beyond the edges of the trench after backfilling has been completed and before the new bituminous base is placed. The thickness of the bituminous concrete base shall be minimum of six inches. The top surface of the bituminous concrete base shall be finished to allow placement of three inches of bituminous concrete wearing surface.
(b) 
Bituminous concrete base shall be three-fourths-inch (binder) pavement placed and compacted in two-inch layers in accordance with the Maine Department of Transportation Standard Specifications for Highways and Bridges, latest edition.

Bituminous paving shall be performed in accordance with MDOT Standard Specifications for Highways and Bridges.
B. 
Bituminous paving on flexible base.
(1) 
When a street opening permit is issued on a street which has been constructed for heavy traffic and has a bituminous surface without a cement concrete base, the same amount of gravel shall be replaced in the trench as is removed when the excavation is made where this material exceeds the twenty-one-inch depth as specified in § 271-33C.

Temporary and permanent surfacing.
(1) 
The contractor to whom a street opening permit has been issued shall provide a temporary patch (coldpatch) of the street opening, generally within 24 hours after the trench has been backfilled and compacted according to the requirements contained in § 271-33C and D.
(2) 
The temporary patch shall be made using premixed bituminous material (coldpatch), which shall remain in place until the permanent patch has been installed.
(3) 
Within 30 calendar days from the date of trench backfill, but not later than November 1, the contractor shall provide permanent pavement replacement in accordance with § 271-34A or B and the detail sheet provided with the permit. For emergency winter work, the permanent trench repair must be completed by June 15.

(2) 
If the applicant does not repair the defective work within 24 hours of notice, then the City Engineer will act to have the work performed by the City, and the applicant shall pay a penalty equal to the whole of said expense incurred by the City, with a surcharge of 50%. No additional permits will be issued to the contractor until this cost has been paid.
