Excavation The trench shall be excavated to the line and grade shown en the plans and to the control survey provided by others. There shall be no classification of excavation. B. Dewatering The trench shall be kept free of water until the backfill iz; adequate to prevent flotation of the pipe. Specifically included is dewatering or diversion of flow at the draen- age ditch crossing near Station 1 + 67. i C. Bedding Belding shall be Class B. The bedding shall be carefully placed to assure continuous support beneath the haunches of the pipe by shovel slicing. D. Backfill Hand placed and compacted backfill shall be native material free from stones larger than two (2) inch diameter, organic material, and debris. It shall be placed by hand and compacted by foot tamping and/or shovel slicing. i Common backfill need not be compacted except where the trench crosses existing streets, driveways, or the drainage ditch. At these points it shall be compacted to 95% maximum density accord- ing to the modified AASHO compaction test. t Bank run gravel may be used in lieu of compaction. E. Unsuitable Material Should unsuitable material be encountered the Engineers may direct its removal and replacement with foundation material according to the provisions of paragraphs 61-2. 34 and 61-3.03D. Foundation j k material may be either Class A nr Class B. I� r S p F. Erosion Prctection i At the crossing of the drainage ditch backfill shall be protected from erosion by jute matting and seeding. The drainage ditch W. O. 6432-D Sanitary Sewer August 3, 1965 P•ge-- - --------101-2 channel shall be restored to its original slopes and jute matting laid over the restored slope. The jute matting shall be of a uniform open plain w; ve of undyed and unbleached single jute yarn. The yarn shall be i a 'loosely twisted construction and shall not vary in thickness by raore than one-half (1 /2) its normal diameter. The matting st-all have a: average wc. ht of 0. 92 pounds/square foot. The up-slope and up-stream end or edge shall be buried in a six (6) inch slot with the soil firmly tamped against it. Laps shall be at least six (6) inches with the up-slope or up-stream lap on top. The matting shall be held in place by Engineer-approved wire staples, pins, spikes, or wooden stakes . Stakes shall be placed at three '3) foot intervals along each strip edge and one (1 ) row alternately spaced in the middle. Ends shall be staked at six (6) inch intervals. Stakes shall be long enough to se urely anc'-ior matting against the soil and driven flush with finished grade. Grass seed of a species native and suitable to the area shall be planted beneath the jute matting. Seed and planting ii,.ethod shall be approved by the Engineers. The planting method shall assure that the seed will germinate to perform its function of erosion contrcl. In lieu of jute matting and seeding, the Contractor may strip sod from the trench section before excavation and stake this sod in place on the drainage ditch channel slopes. In general, the backfill finish grade shall be. shaped and sloped so as to minimize erosion. 101 -06 PIPE MATERIALS Reinforced concrete sewer pipe shall c� '.orm to ASTM Designation C76, Class IV.
