(A) After the pipe has been laid and the joint completed, sand, crushed run stone, grits, bank run sand and gravel or selected trench excavation, if approved by the Director of Utilities, shall be placed and tamped along the sides of the pipe and worked under the sides without “lifting” the pipe or causing other movement which will break the joint or cause the pipe to move off alignment. The foregoing material shall be used as backfill to halfway up the pipe. Select earth backfill shall be placed along the sides of the pipe and thoroughly tamped in six-inch layers up to the top of the pipe. Then, using select material, the trench shall be backfilled by hand up to a point at least six inches over the top of the pipe. Mechanical or other means of accomplishing the balance of the backfill may then be used for filling the remainder of the trench.
(B) At all trench and excavation locations which are subject to traffic, such as in or across streets, highways and driveways, No. 9 aggregate (Ohio State Highway Specifications) or other suitable materials, properly compacted, shall be used for trench backfill. The pavement shall be replaced with a pavement composed of base and wearing courses equal to the original.
