5. If acceptance testing by the QA/QC CONSULTANT indicates that the Clay Liner Material does not meet specified requirements for particle size, classifications, plasticity, or hydraulic conductivity, then the Clay Liner Material which failed will be retested. If the second test results indicate failure to meet the specified requirements, the QA/QC CONSULTANT may order a design modification or the removal, disposal, and replacement of the unsuitable Clay Liner Material. 6. Clay Liner Acceptance: Final acceptance of the clay liner will be based on acceptance and control tests made on completed Work, on material samples taken from the completed layer, and the thickness as calculated from the top of subgrade and top of clay liner surveys. Acceptance testing for final acceptance shall be performed by the soil testing laboratory in accordance with these Specifications and the CQA Manual. G. Protection: 1. Do not route or allow construction traffic, except as necessary, on top of clay liner once material has been placed and compacted. 2. Constructed clay liner shall be maintained to meet the requirements of this Specification until final completion and acceptance of the Work. This shall include all measures to prevent erosion. During seasonal or other extended shutdowns, all exposed surfaces shall be protected as detailed in Article 3.1, PROTECTION OF EXPOSED SURFACES, of this Section. In addition, Amhk the clay liner shall be protected from any contamination which increases the hydraulic conductivity. Any contaminated material shall be removed and replaced at no cost to the OWNER. 3.10 COARSE GRAVEL MATERIAL A. General Requirements: Coarse Gravel shall be placed around leachate collection pipe and in sump area as shown on the Construction Drawings and should be fully encapsulated by geotextile. B. Coarse Gravel Placement: 1. The HDPE geomembrane lining underlying the Coarse Gravel shall be inspected and approved prior to placement of the Coarse Gravel. 2. Equipment used to place and compact the coarse gravel shall not travel directly on the underlying geomembrane and without a minimum 12-inch thickness of GDM in place. 3. Method of dumping and spreading materials shall be approved by the QA/QC CONSULTANT and shall ensure uniform distribution of the material and prevent damage to the underlying geotextile and geomembrane lining. Approval does not absolve the EARTHWORK CONTRACTOR of responsibility for damage to underlying components. 4. Compaction of Coarse Gravel shall be accomplished by shovel-slicing during dumping.
