c. Observe specific pipe or conduit manufacturer's recommendations regardingmethods of backfilling and compaction.d. Ensure compaction of each lift to requirements stated in these specifications.2. Compacted backfill. Perform remaining backfill in accordance with the following:a. Place backfill in lifts not exceeding 8 IN (loose thickness).b. Observe specific pipe or conduit manufacturer's recommendations regardingmethods of backfilling and compaction.c. Exercise extreme care in backfilling operations to avoid displacing joints andappurtenances or causing any horizontal or vertical misalignment, separation, ordistortion. Repair damages, distortions or misalignments to full satisfaction ofContracting Officer.d. All excavated material that cannot be utilized as backfill, or in any othercapacity, shall be removed from the National Monument and properly disposedof by the Contractor. No unused, excavated material shall be stockpiled in theNational Monument.3. Place stored native topsoil as final backfill layer for unimproved areas outside paving.C. Water flushing for consolidation will not be permitted.3.05 COMPACTIONA. Compaction requirements: Place and ensure backfill and fill materials to achieve an equal or "higher"degree of compaction than undisturbed materials adjacent to the work; however, in no case shalldegree of compaction be less than "Minimum Compaction" specified.B. Unless noted otherwise on drawings or specified by other sections of these specifications, complywith following trench compaction criteria.LOCATION SOIL TYPE DENSITYCohesionless soils1. Bedding (pipe zone)materials - all areasCohesive soilsRelative density of 70 percent by ASTMD4253 or D425490 percent of maximum dry density byASTM D1557 or D6982. Compacted Backfill:A. Under pavements,roadways surfaces, withinhighway right-of-waysB. Under turfed, sodded, plantseeded, non-traffic areas.Cohesionless soilsCohesive soilsCohesionless soilsCohesive soilsRelative density of 70 percent by ASTMD4253 or D425495 percent of maximum dry density byASTM D698Relative density of 70 percent by ASTMD4253 or D425490 percent of maximum dry density byASTM D1557 or D698C. Moisture content at time of placement to be as follows:02320 - 504/08 UTILITY TRENCHING AND BACKFILLING
1. Under roadway crossings or pavements, moisture content to be 2 percent plus/minus ofoptimum moisture content, as specified in accordance with ASTM D698.2. In all other areas of trench construction, the moisture content will be adjusted by either thedrying of the materials or wetting of the material to a percentage required to obtain thecompaction as specified.3.06 PAVEMENTA. Temporary Backfill1. All trenches in or adjacent to the National Monument entrance road shall be temporarilybackfilled prior to darkness, weekends, and holidays.B. Permanent Pavement1. Permanent pavement shall conform to the requirements of the San Benito County andCALTRANS Standard Specifications.3.07 FIELD QUALITY CONTROLA. Testing1. Perform inplace moisture density tests as directed by the Contracting Officer to ensure trenchbackfill complies with specified requirements. Pay for all costs associated with compactiondensity tests. Where backfill compaction does not meet moisture density test requirementsand after backfill has been removed as directed by Contracting Officer and situationcorrected, perform additional tests as directed until compaction meets or exceedsrequirements.2. Moisture density tests are to be taken at a minimum of one test every 24 IN lift per 75 linealFT of trench.END OF S<strong>EC</strong>TION02320 - 604/08 UTILITY TRENCHING AND BACKFILLING
