The equipment shall be capable of delivering hot water or steam throughout the section by means of a pre- ASC-5 � • I_-'-J PART DA - ADD1TiONAL SPECIAL CONDITIONS strung hose, which has been pefforated per manufacturer's recommendations, to uniformly raise the water temper�ture above the temperature required to effect a cure of the resin. This tempei��ature shall be determined by the resin/catalyst system employed and shall� be per manufacturer's standards. 4. The heat source shall be fitted with suitabie monitors to gauge the temperature of the incoming and outgoing water or steam supply. Another such gauge shall be placed at the remote manholes to determine the temperatures during cure. Initial cure shall be deemed to be com�leted when inspection of the ex}�osed portions of the cured-in-place pipe appear to� be hard and sound. The cure period shall be of a duration recommended by the resin manufacturer, as modified for the inversion process, during which time the recirculation of the water and/or steam and cycling of the heat exchanger to maintain the temperature continues. 5. Cool-down: The Contractor shall cool the hardened cured-in-place pipe to a temperature below 100 F before relieving the static head in the inversion standpipe. Cool-down may be accomplished by introducing cool water into the anversion standpipe to replace water or steam being drained from a small hole made in the downstream end. Care shall be taken in the release of the static head so that a vacuum will not be de�reloped that could damage the newly installed cured-in-place pipe. � F. SERVICE CONNECTIONS: After the„ pipe has been installed, the Contractor shall reconnect the active service connections. This shall generally be done without excavation, and, in the case of non=man entry pipes, from the interior of the pipeline by means of a television camera and a�cufting device that re-established them to not less than 90 percent capacity.

GROUT PLACEMENT: Grout shall be composed of cement, water and air-entraining admixture and sand mixed in the proportions of 1 part of Portland cement to 3 parts of sand, sufficient water to produce a workable mixture, and that amount of admixture which will entrain sufficient air to produce durable grout, as determined by the ENGINEER. Sand for grouting shall conform to the requirements of paragraph: FINE AGGREGATE. The grout shall be mixed in a concrete mixer in the manner specified for concrete except that the time ofi mixing sha11 be increased to that necessary to produce a mixture having a consistency such as to permit gravity flow into the interstices ofi the riprap with the help of limited spading and brooming. The grout sha11 be used in the work within a period of one (1) hour after mixing. Retempering of ground wilf not be permitted. Riprap shall not be grouted when the ambient temperature is below 35 degree F, or above 95 degrees F. unless approved by the ENGINEER in writing; nor when the grout, without special protection, is likely to be subjected to freezing temperatures before final set has occurred. Prior to grouting, all surFaces of riprap shall be wetted. The riprap shall be grouted in successive longitudinal strips, approximately 10 feet in width, commencing at the lowest strip and working up the slope. Grout shall be brought to the place of final deposit by approved means, and in no case will grout be p�rmitted to flow on the riprapped surface a distance in excess of 10 feet. Immediately after dumping the batch of grout, it shall be distributed over ihe surface of the strip by the use of brooms and the grout worked into place between stones with suitable spades, trowels, or vibrating equipment. As a final operation, the grout shall be removed from the top surfaces of the upper stones and from pockets and depressions in the surface of the stone protection. After completion of any strip as specified, no workman or any load shall be permitted on the grouted surface for a period of at least 24 hours.
