Joint material shall be installed according to the menntectmer's recommendations Auer the gasket has been affixed, the pipe shell be handled to avoid bumping the gasket, kncelmg out of position or loading it with dirt or other foreign material. Any gradd on dwterbed shall be removed, Minced, deaned and relube icded before the joint s made. The pipe shall be properly aligned before the joint is forced home During insertion of the tounge or spigot, the pipe shall be partially supported by hand, sting or sane as required to m+*in+ ;z ^:lateral pressure on the gasket and to maintain concentricity until the gasket is properly poWianed.

The bedding shall be well tamped and made smooth end level to own uniform contact support to the pretest elements All lift holes and the madde and outside face of rubber gesketed joints between precast sections slid be thormaghly wetted, pointed, then Mod with mortar, and smoothed loth inside and .oat Prevost sections shell be placed and aligned to provide vertical -aides and vertical alignment of ladder rouge. The completed manhole shah be rigid, true to dimension and welertight Manholes set in paved drub or other paved areas shall be set to the fmidued grade of the paving. When required, the manhole frame shall be toed to conform to the grade of the payed surface. Manholes not set in paved areas shelf be set at a &Mad grade slightly higher than that at the surrounding terrain to prevent surface water infiltration into the system. Manholes set in unpaved areas shall have an asphalt pad 2' thick and 8' in diameter placed around the manhole reefing. Manholes at the end of a line with no inflow, shall have eloped floor to drain to the outflow K there is fnDmr, a cbennd shall be provided Unless needed to dear a payed road, stab – outs and channel intended to facbate future backup shall be emitted.

Pipe connections jbll be made by use of a rubber boot connector, Kor –N- Send or equal 3 -12 BACKFILLING No bacldiling shall be performed until after the District has inspected the installation of the pipe and bedding and approved' backbiting• The initial badM shall be hand placed select material spread evenly over the bedding material and compacted by hand to an elevation of 6 inches above beefifing will not disturb the pipe in any way. Subsequent No of not more than 2–foot thickness shall be placed as shown an the Standard Details and individually compacted to a mininiu m of 90 percent maxmum density. Subsequent badMmg shall be performed by pushing materiel from the end of the trench : -long and directly one the pipe so that the material will be applied in a rolling slope, rather than by side falling.
