. . ' aa�c � vi i <br /> H. Grasspave2 Sign: A sign to identify 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 shall be provided and installed. <br /> I. Firelane Signage & Deiineation: Firelanes must be identified regarding their entrance and physicat <br /> Location with the placement of signs, gates, curbs, bollards, etc. Specific signage wording and other <br /> details must be coordinated with and approved by local fire authorities. <br /> PART 3 - EXECUTION <br /> 3.01 Iaspection <br /> (It is recammended that Fire Department inspectors be scheduled to inspect instatlation of Grasspave2 <br /> duriag preparation of the suhbase, installation of the base course, and installation of Grasspave2 nnits. <br /> Most sma11 projects can accommoda.te these inspections aIl on the same day. Verify with Fire <br /> Department if certificates of inspection aze 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. Instailation constitutes acceptance of existiag conditians and responsibility for satisfactory <br /> performance. If existing conditions are found unsaxisfactory, contact Project Manager for resotution. <br /> 3.02 Preparation <br /> (Ensure that subbase materials aze structurally adequate to receive designed base course, wearing course, <br /> and designed Ioads. Generally, excavation into undisturbed norma.l: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 dra.inage.) <br /> A. Place base course material over prepared subbase to grades shown on plans, in lifts 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 sand/sod fill to Final Grade. <br /> B. Spread�11 Hydrogrow mix 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 immediately before instatling the Grasspave2 units to assure that the <br /> polymer does not become wet and expanded when installing the units, <br /> 3.03 Installation of Grasspave2 Units <br /> A. Install the Grasspave2 units by piacing units with rings facing up, and using pegs and holes <br /> provided to maintain 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 adjacent hazd-surface pavements. <br /> B. Insta.11 sand in rings as they are Iaid in sections by "backdumping" directly fram a dump truck, or <br /> 6/25/2007 <br />
