Grasspave2 Sign: A sign to ideatify the presence of Grasspave2 paving, stating that special . <br /> maintenance is required, with the Nlanufacturer's phone number, and made of durable materials for 5 6 3 9 <br /> outdoor exposure shail be provided and installed. <br /> I. Firelane Si,pnage & Deiineation: Firelanes must be identified regarding their entrance and physical <br /> tocation with the placement of signs, gates, curbs, bollards, etc. Specific signage wording and other <br /> details must be coordinated with and approved by Iocal fue authorities. <br /> PART 3 - EXECUTION <br /> 3.01 Iaspectioe <br /> (It is recommended that Fire Department inspectors be scheduled to inspect instatlation of Grasspave2 <br /> during preparation of the subbase, installation of the base course, and installation of Grasspave2 units. <br /> Most smaIl projects can accommodate these inspections aIl on the same da.y. Verify with Fire <br /> Department if certificates of inspection are required.} <br /> A. Examine subgrade and base course installed conditions. Do not start Grasspave2 installation <br /> until unsatisfactory conditions are corrected. Check for improperly compacted trenches, debris, and <br /> improper gradients. <br /> B. Installation constitutes acceptance of existing conditions and responsibility for satisfactory <br /> performance. If existing conditions are found unsatisfactory, coatact Project Manager for resotution. <br /> 3.02 Preparallon <br /> (Ensure that subhase materials aze structura.ity adequa.te to receive designed base course, wearing course, <br /> and c3esigned Ioads. Generally, excavation into undisturbed normal strength soils will require no <br /> additional modification. Fill soils and otherwise structurally weak soils may require modifications, such <br /> as geotextiles, geogrids, and/or compaction(not to exceed 90%). Ensure that grading and soil porosity <br /> of the subbase will provide adequate subsurface drainage.} <br /> A. Place base course material over prepared subbase to grades shown on plans, in Iifts not to exceed <br /> 150 mm(6"), compacting each lift separately to 95% Modified Proctor. Leave minimum 25 mm(1") to <br /> 35 mm(1.5") for Grasspave2 unit and sandlsod fill to Final Grade. <br /> B. Spread all Hydrogrow mi:c provided (spreader rate =4.53 kg per 100 m2 (10 lbs per 1076 ft2) <br /> evenly over the surface of the base course with a hand-held, or wheeled,rotary spreader. The <br /> Hydrogrow mix should be placed 'unmediately before instailing the Grasspave2 units to assure that the <br /> polymer does not become wet and expanded wtten instailing the units. <br /> 3.03 Installation of Grasspave2 Units <br /> A. Install the Grasspave2 units by piacing un'tts with rings facing up, and using pegs and holes <br /> provided to mainta.in proper spacing and interlock the units. Units can be easily shaped with pruning <br /> shears or knife. Units placed on curves and slopes shall be anchored to the base course, using 16d <br /> Common nails with fender washer, as required to secure units in place. Tops of rings shall be between 6 <br /> mm to 13 mm(0.2�" to 0.5") below the surface of ad,jacent hard-surface pavements. <br /> B. Install sand in rings as they are Iaid in sections by "backdumping" directly from a dump truck, or <br /> 6/25/2007 <br />
