with these Specifications and the CQA Manual. <br /> G. Protection: <br /> 1. Do not route or allow construction traffic, except as necessary, on top of <br /> clay liner once material has been placed and compacted. <br /> 2. Constructed clay liner shall be maintained to meet the requirements of this <br /> Specification until final completion and acceptance of the Work. This shall <br /> include all measures to prevent erosion. During seasonal or other extended <br /> shutdowns, all exposed surfaces shall be protected as detailed in Article 3.1, <br /> PROTECTION OF EXPOSED SURFACES, of this Section. In addition, <br /> the clay liner shall be protected from any contamination that increases the <br /> hydraulic conductivity. Any contaminated material shall be removed and <br /> replaced at no cost to the OWNER. <br /> 3.10 CONSTRUCTION OF CLAY EARTHFILL <br /> A. General: <br /> 3. Clay Earthfill Material shall be processed to meet the requirements of <br /> Article 2.5 of this Specification. The EARTHWORK CONTRACTOR <br /> shall have the option to determine construction procedures to be used, <br /> subject to the approval and acceptance testing by the QA/QC <br /> CONSULTANT. <br /> 4. The EARTHWORK CONTRACTOR shall process the Clay Earthfill • <br /> Material suitable for the purpose intended. After processing, the Clay <br /> Earthfill Material shall be free from dry clods, roots, organic matter, frozen <br /> material, debris, rocks or stones larger than 1 inch, and other deleterious <br /> material. Clay Earthfill Material shall be thoroughly blended and <br /> compacted to provide a homogeneous material relatively uniform in <br /> gradation and moisture content. <br /> 5. The Clay Earthfill Material shall be as uniform as possible, free of <br /> penetrating cracks, and having interlift boundaries completely blended. The <br /> soil shall be compacted to produce a soil structure having low hydraulic <br /> conductivity. <br /> B. Compaction: <br /> 1. Soil shall be spread evenly over the prepared subgrade with a thickness as <br /> required to achieve a 6-inch compacted lift, with a maximum 8-inch loose <br /> lift. <br /> 2. The minimum final thickness and extent of the Clay Earthfill shall be as <br /> shown on the Construction Drawings. <br /> 3. Moisture conditioning shall be uniform throughout each lift <br /> 4. The Clay Earthfill material shall be compacted in-place to a minimum dry <br /> density of 90 percent relative compaction at a water content of 3 to <br /> 5 percent greater than the optimum water content as measured by ASTM <br /> Forward Landfill WMU FU-17 <br /> 02300 17 EARTHWORK <br />
