Whereas, the Council deems it necessary to establish a firm policy for backfilling of excavations and replacement of pavement disturbed as a result of making an opening or excavation in any street, these specifications are set forth and the compliance therewith shall be a requirement of obtaining a permit for said opening or excavation; it shall be the obligation of any person obtaining a permit for an opening or excavation in the public right-of-way to backfill the excavation and replace the pavement as set forth in these specifications.
(A) Backfill. All excavations under pavement shall be backfilled with a reasonably clean granular material with good compaction qualities. The material shall be replaced in layers not to exceed six inches in depth. Each layer shall be thoroughly tamped with a vibratory type mechanical tamper. Special care shall be taken in filling around sewers, water pipes, gas lines and the like to keep the earth at the same height on both sides to avoid shifting of the pipe line. No removed paving materials or debris shall be used in backfilling the excavation. Excavations not under a pavement shall be backfilled with virgin material removed from the excavation by approval of the Town Council or its designated representatives.
(B) Pavement replacer. All pavement shall be replaced with a type of construction equal to or better than that which is removed as approved by the town’s Street Commissioner. All cuts in concrete pavements shall be first outlined with a saw cut not less than one inch to one and one-half inches.
(C) Concrete or brick pavements.
(1) Concrete used in the replacement of concrete or brick pavements not presently surfaced with an asphaltic material shall consist of not less than six bags of air entrained, Type 1-A, portland cement per cubic yard. Slump shall not exceed three inches. Course aggregate shall be limestone or blast furnace slag. No natural gravel aggregate will be allowed. Brick pavements will be replaced with eight inches of concrete, except in some residential streets where the town may require the brick to be replaced.
(2) Where concrete that has an asphaltic concrete surface is replaced, Type I, portland cement shall be used, and the concrete shall be finished flush with the surface of the existing concrete and the asphaltic surface replaced.
(D) Hot asphaltic concrete, sheet asphalt, emulsified asphalt, chip and seals, and oil mat pavements. All asphaltic and oil type pavements sh all be replaced with a hot asphaltic concrete surface conforming to § D-3, Hot Asphaltic Concrete Base, Binder, and Surface of the latest State Highway Standard Specifications. The thickness of the pavement shall be equal to that which existed, but not less than three inches. Not less than eight inches of Coarse Aggregate, Class A or B, Size No. 53, § K-3, or the State Highway Specifications, shall be placed under any asphaltic concrete patch unless a concrete base is necessary. Asphalt placed under a concrete patch shall be cut back six inches around the concrete patch so that the two joints are offset.
(E) Temporary patch. It if is not possible, due to weather conditions, for the contractor to replace the pavement within 14 days following completion of the work, a coarse aggregate base eight inches thick and a cold asphaltic surface shall be applied and maintained as a temporary patch until pavement repairs can be made. In no case shall a temporary patch be maintained more than six months before permanent repairs are made.
