The roll direcUon of Miragrid should be laid in the direction <br /> of main reinforcement. The conUaclor shall be responsible for correct orientelbn. <br /> Reinforcement should be placed coincident with the compaction ifft nearest the ! <br /> �— �� design elevation on lhe drawing. No partial or half-lifl thickness are required. Geogrids i <br /> '^-� can be placed directly on lhe ex(sling fill surface. No special surface treatment, leveling I <br /> or smoothing, is required.

Adjacent roll widths I <br /> '"�� should overlap a minimum of 4 tnches. Mechanical connections between edjacent rolls ' <br /> can•be made at this time, if required. CeAain fill propenies, fiil placement prxedures, <br /> j( � and/or weather condftions may require the reinforcement to be held in place by slaples, <br /> pins, sand bags, or flll,as directed by the engineer. <br /> The reinforcing maler(al should be cul lo length as shown on the contract drawfngs. ! <br /> �1•�•-� A razor blade, scfsaoro, or aherp knife ere acceptable instruments lo cut lhe materiaL � <br /> Should it be necessary to section a roll width, a high speed, abrasive saw or vibrating <br /> knife edge works well. <br /> 1��j <br /> i <br /> I <br />
