In cases of emergency or at times when the City offices are closed, such notification and inspection arrangements shall be made at the earliest time possible after such paving out has been made. For purposes of this Ordinance, "person" is illustrated by but not limited to any firm, utility company, corporation or construction company. SECTION 2: PAVEMENT REPLACEMENT: The Contractor shall repair a� pavement that he cuts. All pavement replacement shall be performed immediately after the pipe laying operations so that the area can be re -opened for traffic as soon as practical. Where pavement is to be patched, the Contractor shall tamp all of the backfill in the trench with air tamps in layers not exceeding 4 inches in thickness. Each layer shall be tamped until it is at the same or greater density as the soil in the undisturbed earth adjoining the trench. The earth backfill shall be tamped from the bottom of the trench to the level of the subgrade of the paving base. This tamping shall be performed as soon as the pipe has been laid. If additional earth is required to complete the backfill of the trench under pavement, the Contractor shall haul the dirt in. If excess spoil remains after the tamping of the badfill is completed, the Contractor shall dispose of the excess immediately. As soon as the tamping is completed, the Contractor shall immediately pour the base for the pavement. The base shall consist of six (6) inches of concrete mixed using high-early strength concrete. As soon as the concrete has set, the Contractor shall cover the concrete with paper curing mats, or with cloth mats that have been thoroughly soaked with water, and allow the concrete base to cure for 24 hours. After 24 hours curing time, the Contractor shall complete the pavement replacement immediately. If the original pavement was asphalt, the Contractor shall install a rock asphalt wearing course. Before applying the rock asphalt, the Contractor shall clean the surface of the concrete base course completely and apply a tack coat of RC-2 to the surface at the rate of 1/4 gallon per square yard. This tack coat shall be mopped on and shall cover the surface of the concrete completely. The Contractor may out back the RC-2 with white gasoline if necessary to make it cover the surface without applying an excessive amount of RC-2. The fresh asphalt shall be covered immediately with a thin, uniform layer of clean, sharp sand. The rock asphalt shell be applied at the rate of one ton to each 13 square yards and thoroughly rolled with a flat wheel roller weighing 300 lbs. per linear inch. The roller surface may be moistened lightly with water occasionally if necessary to prevent the rock asphalt from adhering to the roller. The compacted thickness of the rock asphalt shall average ll§ inch, and it shall not be less than one (1) inch thick at any place. The finished surface of the rock asphalt shall be at the same elevation and grade as was the original pavement before cutting. In the event there is any settlement in the rock asphalt pavement patch, the Contractor shall apply a new tack coat to the surface of the pavement and build it back up to the original grade with additional rock asphalt. Where it is necessary for the Contractor to out concrete pavement, including driveways more than eight-feet wide, he shall furnish a concrete saw and saw two parallel lines in the concrete with the distance between the saw cuts being 12 inches more than the ditch width. The depth of the saw out shall be not less than two (2) inches. He shall then break out and dispose of the concrete between the saw cuts where the ditch is to be excavated. The backfill in this area shall be air tamped as previously described. The pavement patch in these areas shall be made with eight (B) inches of the high-early strength concrete, rather than a six (6) inch concrete base with a different wearing course as described for asphalt and brick pavements. The surface of the concrete pavement patch shall be flush with the adjoining concrete pavement. After the concrete has been poured and set up thumbprint bard, it shall be trowelled smooth and then brushed lightly with a soft brush to give a non-slip finish. No topping will be permitted on the concrete pavement patch. After the brushing process, the concrete shall be permitted to set hard; then it shall be covered for 24 hours with a curing mat. In the event settlement occurs in the concrete pavement patch, the Contractor shall chip out the patch to a minimum depth of 1'5 inch, clean the chipped surface of the concrete thoroughly to remove all dirt, chipped concrete, etx., paint it with a slush coat of one part Portland cement and one part Embeco, or approved equal, mixed with sufficient water to make a creamy mixture, and then fill the patch back to the property elevation with Etmbeco mortar mixed with one part Portland cement, one part concrete sand, and one part Embeco, or approved equal, mixed with the proper water to give the correct consistency. The patch shall be trowelled, brushed and cured. All pavement replacement shall be done immediately after the pipe is laid in each section, so that the street can be opened for traffic just as soon as possible. The Contractor shall maintain lights and barricades around the work areas until the pavement is replaced and ready for traffic. The Contractor shall perform the pavement patching as soon as possible and shall open the patched area for traffic as soon as possible. In the event the Engineer is of the opinion that the Contractor is not performing his pavement patching with all proper diligence to keep it immediately behind his pipe laying operation, or is opening excessive length of ditch ahead of the pipe laying, the right is reserved for the Engineer to require the Contractor to cease any further excavation until the pavement patching is completed up to immediately behind the point of excavation. The pavement patching payment will be based on the amount of patching required for a reasonable amount of excavation for the pipe laying. Before the patching is begun, the Contractor shall cut the pavement and base material back to a straight end on solid, undisturbed soil. Normally, this should be about six (6) inches back from the edges of the trench, which should be 12 inches wider than the outside diameter of the pipe, so the normal pavement patch should be about 24 inches wider than the outside diameter of the pipe. In the event the Contractor makes excessive excavation, he shall perform all pavement patch required, but he shall be paid only for the pavement required for a normal width of patch. In the event it is necessary for the Contractor to out pavement to repair a leak, or to perform other work that should have been done as the pipe was being laid, the pavement patching required by this work shall be performed by the Contractor without payment. SECTION 3: BACKFILL AND CLEANUP: Where the pipe is laid in paved streets, the backfill shall be tamped from the bottom of the ditch to the top as described in the section on pavement replacement. Where the pipe is laid in oiled, gravelled, or dirt streets, or at any location where there is not any pavement, the backfill shall be performed as described in this section. After the pipe has been bedded as previously specified, additional backfill may be made by machinery or otherwise until the trench is backfilled to approximately 12 inches of the ground level. The trench shall then be flooded with water until water is standing or running over the top of the backfill. This water will be furnished without charge by the Owner, but the Contractor must furnish his own pipe, hose, tools, and whatever else is needed to get the water from the nearest fire hydrant or outlet on the new pipe to where the water is needed. In general, the water can be put in the trench from a fire hydrant and hose to a high point in the line, and allowed to flow down the trench to the valleys. After the trench has been flooded to the satisfaction of the Engineer, the backfill shall then be completed immediately while there is still water in the trench and the preceding backfill is still saturated. Any surplus spoil remaining shall be either pushed aside out of the way, if possible to do so without hindering the surface drainage in the area, or hauled off if necessary to gat it out of the way. After each rain, or at any other time the backfill in the ditches settles, the Contractor shall add more dirt to the ditches and level off the surface again. During the time the backfill in the ditches remains soft after flooding, the Contractor shall keep flares burning and barricades erected if necessary to keep the traffic off the ditebline until the backfill has dried and consolidated to the point where the backfill will support the traffic. As the backfilling is being performed, all materials that were surplus in that area, and all the construction debris shall be removed and the area cleaned up. The backfilling may be performed with a bulldozer or any other machinery the Contractor cares to use, the cleanup of the area after the trench has been flooded shall be made with a maintainer. The Contractor shall also use the maintainer to keep the ditebline and surrounding area smooth and uniform after the backfill dries and consolidates, and he shall clean up the ditchlines with the maintainer whenever they become rough or sunk -in or otherwise require maintenance. The Contractor will not be required to replace oiled dirt, gravel, grass, or any surface that he is directed to out other than pavement. The Contractor shall maintain the backfilled ditches in a condition not hazardous to traffic from the time the ditch is backfilled until the job is accepted as finally complete by the Owner. The Contractor shall make his cleanup immediately behind his pipe laying operations. He shall not have more than 1,000 feet of ditch open per trenching machine and pipe laying crew at any one time. In the event any ditching machine gets as far as 1,000 feet ahead of the backfilling, he shell shut down his machine and direct his activities to getting the pipe laid up to the machine and getting the backfill in the trench up to the point the pipe is laid to. After the pipe has been laid and the job appears to be complete and ready for final inspection, before this in- spection, the Contractor shall go back over all diteblines with his maintainer and grade them up smooth and even in first class shape. He shall dispose of any excess earth remaining and shall remove any final construction debris remaining. The Contractor will be required to perform any work necessary to provide access to driveways blocked by his ditching operations as soon as possible. This includes backfilling in front of the driveways as soon as possible, and adding gravel in line with the driveways when the backfill is too wet for the earth to support a car, or provide other suitable means of access to the driveways. This work shall be done and materials necessary furnished by the Contractor without additional payment other than the contract price for the pipe per foot. SECTION 4: PENALTY: Every person who shall omit or refuse to comply with, or who violates any of the provisions of this Ordinance, shall be deemed guilty of a misdemeanor and upon conviction thereof shall be fined in any sum not more than two hundred dollars ($200.00) for each offense and each and every day that the provisions of this Ordinance are violated shall constitute a separate offense; provided, however, that such penal provision shall not preclude a suit to enjoin such violation. SECTION 5: REPEAL: All Ordinances or parts of ordinances in conflict herewith are hereby repealed and declared of no further force and effect.
