te . The pipe spigot shall be centered in and aligned with its mating bell prior to insertion and forced evenly in a straight line to seating depth, taking care not to over-bell the joint. Where required, deflections shall be made after the joint is seated. f. Joining shall generally be done by hand or by push-bar with a cushion block whenever pipe size and weight permit. When a mechanical pushing/pulling device such as chain-puller, come- ' along, and the like is required, the device shall be used in a manner that will not deform gouge, chip, or otherwise damage the pipe or cause significant disturbance of the prepared bedding. In no case ' shall joints be made by "popping-on" or swinging the spigot into the bell to seat the joint. ' g . Fittings and appurtenances shall be fully, independently supported on the bedding or on a permanent foundation so as not to bear on the pipe upon completion of the installation. h .

Standard Specifications for Road and Bridge Construction. Backfill shall be placed in lifts not to exceed 12 inches loose depth and compacted to 95 ' percent of maximum density per AASHTO T- 180 in unpaved areas and to required subgrade density in areas of paving or curbing . ' 3 ) Density tests shall be taken on the compacted backfill at all manholes . There shall be a minimum of one test location for each manhole . The test location shall be taken at the location designated by the Engineer' s representative . ' The density tests shall be taken at each location at one foot intervals beginning at the bottom of the excavation and ending at the final grade . The costs of all testing shall be paid for by the Contractor. ' CADown1oad\techspec-0260Ldoc SC601 - 10
