4.5.1.3. Site specific compaction requirements should be followed in <br /> accordance with the project drawings and specifications. At a <br /> minimum,the level of compaction should be such that no rutting is <br /> caused by installation equipment or other construction vehicles which <br /> traffic the area of deployment(typically 85% of standard proctor or <br /> greater). <br /> 4.5.1.4. The surfaces to be lined shall be smooth and free of any debris, <br /> vegetation, roots, sticks, sharp rocks, or other deleterious materials <br /> larger than two inches as well as free of any voids, large cracks or <br /> standing water or ice. <br /> 4.5.1.5. Directly prior to deployment of the GCL, the subgrade shall be final- <br /> graded to fill remaining voids or desiccation cracks to eliminate sharp <br /> irregularities or abrupt elevation changes. The surfaces to be lined <br /> shall be maintained in this smooth condition. <br /> 4.5.2. Geosynthetic Subgrade - Prior to GCL deployment the geosynthetic surface as <br /> well as other underlying geosynthetics upon which the GCL material will be <br /> installed shall be inspected and approved by the third party CQA inspector in <br /> accordance with the requirements of the project specification documents. <br /> 4.5.3. Anchor Trench - An anchor trench shall be excavated by the earthwork <br /> contractor or liner installer to the lines and grades shown on the project <br /> drawings at the top of slopes. <br /> 4.5.3.1. The anchor trench shall be constructed free of sharp edges or corners <br /> and maintained in a dry condition. No loose soil shall be permitted <br /> beneath the GCL within the trench. <br /> 4.5.3.2. The anchor trench shall be inspected and approved by the CQA <br /> inspector prior to GCL placement, back-filling and compaction of the <br /> anchor key material. <br /> 4.5.4. Subsrade Inspection - The earthen or geosynthetic subgrade shall be <br /> continuously inspected, approved and certified by the CQA inspector prior to <br /> GCL placement. <br /> Subsequent to the CQA inspector's approval, it shall be the installer's <br /> responsibility to indicate to the Engineer any change in the subgrade condition <br /> that could cause it to be out of compliance with any of the requirements of this <br /> section or the project specification. <br /> 4.6. GCL Placement- GCL Material shall be placed in general accordance with the <br /> procedures specified below, or modified to account for site specific conditions. <br /> 4.6.1. GCL Orientation - GCL panels should be placed with the nonwoven side up <br /> (heat burnished side down)to maximize the shear strength characteristics. <br /> In base or flat areas,the GCL does not require any particular orientation. <br /> 4.6.2. GCL Panel Position - Where possible, all slope panels should be installed <br /> parallel to the maximum slope while panels installed in flat areas require no <br /> particular orientation. <br /> Bentofix Drop-In Specification Bentofix is a registered trademark of NAVE GmbH&Co.KG <br /> 9 RI/13/06 <br />
