All open drains will be cut to natural surface and will not contain fill material unless otherwise directed by the Supervisor. The height of concrete stabilised backfill above the top of the culvert will be as shown on the drawings. Compaction of the backfill material will be by hand operated mechanical vibratory compaction equipment. The mortar mix and method to be used will be approved by the Supervisor. Rock pitching will be placed in the mortar whilst still wet, each rock being hand placed and firmly bedded into the mortar and against adjoining rocks. Rock pitching will proceed in a similar upward progression up the angle being covered, following the mortar bedding.
Rock pitching shall be placed in the mortar whilst still wet, each rock being hand placed and firmly bedded into the mortar and against adjoining rocks. Rock pitching shall proceed in a similar upward progression up the slope being covered, following the mortar bedding. On the day after the placement of the rocks, a stiff cement mortar mix shall be carefully worked in to the joints between adjacent rocks to provide an even, solid, tight surface. The mortar mix and method to be used shall be approved by the Superintendent.
Open drains shall include table rains, catch drains and dispersal drains. All open drains shall be constructed to the levels and grades shown on the drawings. All open drains shall be cut to natural surface and shall not contain fill material unless otherwise directed by the Superintendent. Embedded steelwork included in the concrete structures such as open grating, support channels, manhole cover and the like shall be constructed to the details shown on the drawings and in compliance with the specification.
Backfill shall be placed equally each side of the culvert to avoid disturbing the approved installed box culvert. The depth of cement stabilised backfill above the top of the culvert shall be as shown on the drawings. Additional backfill material shall be placed on top of the cement stabilised backfill as required to obtain correct finished levels. This material shall be as detailed on the drawings. Backfill shall be placed equally each side of the pope to avoid disturbing the approved installed pipe conduit.
Suitable backfill material shall be placed around the pipe to a depth of 300 mm above the top of the pipe or as detailed on the drawings. The remainder of the trench shall be backfilled to finished ground level with material previously excavated from the trench. All backfill shall be compacted to 90% of maximum dry density as measured by AS 1289 Part 3, except under roadways and access areas where the backfill shall be compacted to 95% of maximum dry density. Compaction of the backfill material shall be by hand operated mechanical vibratory compaction equipment. Compaction shall not be used within 150 mm of the pipe.
