3.16 TERMINATION AND ROAD BERMS <br /> A. Construct termination and road berms of general earthfill as shown on the <br /> Construction Drawings. Place material in lifts not exceeding 1-foot depth (after <br /> compaction) and compact each lift to approximately 85 percent relative <br /> compaction (ASTM D 1557). <br /> B. The EARTHWORK CONTRACTOR shall repair or replace any geosynthetic <br /> materials damaged during placement and compaction of the termination berms, at <br /> the EARTHWORK CONTRACTOR's sole expense. <br /> C. All geosynthetic materials underlying the berms will be inspected and approved <br /> by the QA/QC CONSULTANT prior to placement of the general earthfill. <br /> D. During all compacting operations, maintain optimum practicable moisture content <br /> required for compaction purposes in each lift of fill. Maintain uniform moisture <br /> content throughout the lift. Insofar as practicable, add water to the material at the <br /> site of excavation. Supplement, if required, by sprinkling the general earthfill. At <br /> the time of compaction, the water content of the material shall be at the optimum <br /> moisture content,±4 percentage points per ASTM D1557. <br /> E. Do not attempt to compact general earthfill material that contains excessive <br /> moisture. Aerate material by blading, discing, harrowing, or other methods, to <br /> hasten the drying process. <br /> 3.17 DITCHES AND TRENCHES <br /> A. Place general earthfill, as necessary, and excavate ditches and trenches to achieve <br /> grade and dimensions shown on the Construction Drawings. <br /> B. Excavate, as necessary, to repair any existing drainage structure damaged during <br /> construction. <br /> C. Minimum width of trenches shall be 12-inches greater than outside diameter or <br /> width of pipe. Maximum trench width is unlimited, unless otherwise shown or <br /> specified, or unless width will cause damage to existing facilities, adjacent <br /> property, or completed work. <br /> D. Pipe bedding grooves shall be semi circular, trapezoidal, or 90 degree V. The <br /> grooves shall be excavated or plowed into the trench bottom. Forming groove by <br /> compaction will not be acceptable. <br /> 3.18 SLURRY CEMENT MIXTURE <br /> A. Place slurry cement mixture at the locations shown on the Construction Drawings. <br /> FORWARD LANDFILL 02300 <br /> 24 EARTHWORK <br />
