The rock fill or amended soil backfill shall be placed and compacted until a stable surface is achieved. 3.3 REGRADING AND FOUNDATION PAD FILL PLACEMENT A. Contractor shall conduct regrading operations in a manner that will allow continued free drainage of the working surface and the immediately surrounding areas, to the extent Earthwork and Trenching 3.6 1. Use filter fabric where necessary around Stabilization Material, Granular Bedding Material and on the subgrade to stabilize subgrade and prevent fmes from migrating intogranular materials. G. Level and roll subgrade so that surface materials will be compact and bond well with the first layer of the backfill, fill or embankment. H. Underlay slabs on grade with a minimum of 4 inches of granular material, or greater depth if shown on Drawings, covered by 8 mil polyethylene sheeting. I. Place and compact fill to an elevation at least one foot above top of proposed pipe where pipe will pass through backfill or fill prior to beginning trenching. BACKFILL, FILL AND EMBANKMENT A. Import material if compaction cannot be obtained with job excavated material or if job excavated material does not meet the specifications. B. Use of rocks or stones within the allowable size limit in the remainder of backfills, trenches, fills or embanlanents is subject to their not interfering with proper compaction. C. Place on suitably prepared subgrade. D. Spread and compact materials in horizontal lifts not exceeding 8 inches in uncompacted thickness. 1. Spread and level material deposited in piles or windrows prior to compaction. 2. Distribute material so as to preclude the formation of lenses of material differing from the surrounding materials. E. Fill voids caused by excavation of unsuitable material with granular material in areas where structures, foundations, or slabs will be constructed F. Compaction Around Structures. 1. Mechanically compact. a. Use platform type tampers or similar equipment. b. Rolling is permitted provided proper compaction is obtained and adequate measures are taken to prevent damage to structures. 2. Do not backfill against new concrete walls less than 14 days after removal of forms. a. Do not exceed ten (10) foot heights with backfill in less than 21 days after removal of forms. G. Compquipment. action E 1. Use equipment suited to the soil being compacted. 2. Sheepsfoot Roller: If used, provide with cleaner bars so attached as to prevent the accumulation of material between the tamper feet. 3. Rollers: designed so that the effective weight can be increased. Earthwork and Trenching g 02200-8 SECTION 02630 STORM DRAINAGE PART 1 - GENERAL 1.1 DESCRIPTION A.
