Grasspave2 Sign: A sign to identify the presence of Grasspave2 paving, stating that special maintenance is required, with the Nlanufacturer's phone number, and made of durable materials for 5 6 3 9� outdoor exposure shall be provided and installed. I. Firelane Signage & Deiineation: Firelanes must be identified regarding their entrance and physicat Location with the placement of signs, gates, curbs, bollards, etc. Specific signage wording and other details must be coordinated with and approved by local fire authorities. PART 3 - EXECUTION 3.01 Iaspection (It is recammended that Fire Department inspectors be scheduled to inspect instatlation of Grasspave2 duriag preparation of the suhbase, installation of the base course, and installation of Grasspave2 nnits. Most sma11 projects can accommoda.te these inspections aIl on the same day. Verify with Fire Department if certificates of inspection aze required.) A. Examine subgrade and base course installed conditions. Do not start Grasspave2 installation until unsatisfactory conditions are corrected. Check for improperly compacted trenches, debris, and improper gradients. B. Instailation constitutes acceptance of existiag conditians and responsibility for satisfactory performance. If existing conditions are found unsaxisfactory, contact Project Manager for resotution. 3.02 Preparation (Ensure that subbase materials aze structurally adequate to receive designed base course, wearing course, and designed Ioads. Generally, excavation into undisturbed norma.l:strength soils will require no additional modification. Fill soils and otherwise structurally weak soils may require modifications, such as geotextiles, geogrids, and/or compaction(not to exceed 90%). Ensure that grading and soil porosity of the subbase will provide adequate subsurface dra.inage.) A. Place base course material over prepared subbase to grades shown on plans, in lifts not to exceed 150 mm (6"), compacting each lift separately to 95% Modified Proctor. Leave minimum 25 mm(1") to 35 mm (1.5") for Grasspave2 unit and sand/sod fill to Final Grade. B. Spread�11 Hydrogrow mix provided (spreader rate=4.53 kg per 100 m2 (10 lbs per 1076 ft2) evenly over the surface of the base course with a hand-held, or wheeled,rotary spreader. The Hydrogrow mix should be placed immediately before instatling the Grasspave2 units to assure that the polymer does not become wet and expanded when installing the units, 3.03 Installation of Grasspave2 Units A. Install the Grasspave2 units by piacing units with rings facing up, and using pegs and holes provided to maintain proper spacing and interlock the units. Units can be easily shaped with pruning shears or knife. Units placed on curves and slopes shall be anchored to the base course, using 16d Common nails with fender washer, as required to secure units in place. Tops of rings shall be between 6 mm to 13 mm (0.2�" to 0.5") below the surface of adjacent hazd-surface pavements. B. Insta.11 sand in rings as they are Iaid in sections by "backdumping" directly fram a dump truck, or 6/25/2007 , i ar,�c �vi � (Crushed shell and limerock alone can set up Iike concrete without sand added.) � ( 3 q B. Hydrogrow Mix: A mixture made &om several commercial products including: 1)cr�ss-Iinked � polyacrylimide (<0.1%)polymer, which is non-toxic and neutral in pH, and will absorb l�Q to 350 times its weight in water&om most tap sources; 2) ZeoPro zeolite minerai, amended with small amounts of starter fertilizers, from Zeoponix, Inc.; 3)Isotite porous ceramic, designed to hold lazge amounts of water without physical degra.dation ar change of size oF particle, from Sumitomo Crroup; 4)and aggromolated Humate, a natural source of nutrients and micronutrients, from Tri-C Enterprises. C. Grasspave2 Cnass Paving Units: Lightweight injection-molded plastic units O.�x0.5x0.02� m (20"x20"x1" t�igh, 2.7 ft2 each) with hollow rings rising from a strong open grid allowing maximum grass root penetration and development. The plastic shaIl be 1Q0%post-consumer recycted plastic resins, predominately HDPE, with muumum 3%cazbon black cancentrate added for W protection. Loading capability is equal to 402 kg/cm2 (�700 psi)when filled with sand, over an appropriate depth of roadbase. Standard color is black. Uait weight= SIO g (18 oz.), volume = 8% solid. Units may also be shipped in pre-assembled into rolls that vary from 10 square meters (1 Q8 s fl to 125 square meters (1345 s�}. D. Sand: Obtain clean sharp sand(washed concrete sand}to fill the 2� mm (one inch) high rings and spaces between the rings when seeding or using 13 mm(half inch) thick sod(soil thickness}. E. Grass: Use species resistant to weaz by tra�c generally a Btue/Rye/Fescue mix used for axhletic fields in northern climates,and Zoysia, Fescue, or Berrnuda rypes in southem climates. (Check with Iocal sod and seed suppliers for preferred mixtures.) (Dedicated firelanes can use same grass species used on surrounding turf.) - (Parking apptications require greatest wear-resistant species possible, generally available only by seed or sprigging.) (Choose one of the following paragraphs to suit project requirements.} 1. Sod: Use 13 mm(0.5") thick(soil tluckness) rolled sod from a reputable local grower. Species should be wear resistant, free from disease, and in excellent condition. Sod sha.11 be grown in sand or sandy loam soils oniy. Sod grown in soils of clay, silt, or high organic materials such as peat, will not be accepted. 2. Seed: Use seed materials, of the preferred species for local envirotunental and projected tr�c conditions, from certified sources. Seed shall be provided in containers clearly labeled to show seed name, lat number, net weight, %weed seed conteat,and guaranteed% of purity and gerrnination. Pure Live Seed types and arnount shall be as shown on plaas. F. Mulch: (Needed only for seeding.) Shall be of wood or paper cellulose types of commercial mulch materials often used in conjunction with hydroseeding operations. Mulches of straw, pine needles, etc. will aot be accepta.ble because of their low moisture holding capacity. G. Fertilizer: A commercial "starter" fertilizer, with Guaranteed Analysis of 17-23-6, or as � recommended by locai grass supplier,for rapid germination and root development. 6/25/2007 . Page 3 of 7 shipped in flat sheets that measure I-meter(40") square. 2. Do not build on frozen work ar wet,satura.ted or muddy subgrade. 5 6 � 9 E. Protect partially completed paving against damage from other construction traffic when work is in progress, and until grass root system has matured (about 3 to 4 weeks). Any bazricades constructed must still be accessible by emergency and fire equipment during and a.fter installation. F. Protect adjacent work from damage dtaring Grasspave2 insta.tlation.

Base Course: Sandy gravel material from local sources commonly used for road base construction, passing the following sieve analysis. % Passine Sieve Size 100 3/4" 85 3/8" 60 #4. 30 #4.0 < 3 #200 1. Sources of the material can include either"pit run" or"crusher run." Crusher run material wiIl generally require sharp sand to be added to mixture (33% by volume} to ensure long term porosity. If there is difficuiry in finding Iocal sources to meet this sieve analysis, and alternative mixture can be created by mixing 2/3 crushed drainage rock (0.7�"dia) with 1/3 concrete or river sand. 2. Selected materials should be neaziy neutral in pH (range from 6.5 to 7.2) to provide adequate root zone develapment for turf. 3. Alternative materials such as crushed shell, limerock, and/or crushed lava may be considered for base course use, provided they are mixed with sharp sand (33%), and brought to proper compacrion. 6/25!2Q07 _ ..o B.

Generally, Grasspave2 is installed at the same time as project grass installation, neazly the last site construction activity. B. A!1 hard surface paving adjacent to Grasspave2 azeas, including concrete walks and asphatt paving must be completed prior to instailation of Grasspave2. C. Gradients for grass porous paving surfaces can vary fram flat to 20%, depending upoa vehicle types to use the surface. Please note that firelanes, or other emergency vehicles,will generally require a gradient that is less than 6%. If there aze any questions regarding existing gradients on this project, please contact the Project Designer, or Invisibie Structures, Inc. D. Cold weather: 1. Do not use frozen materials or materials mixed or coated with ice or frost. Be careful in handIing rolls of Grasspave2 in temperatures below 50 degrees F, as product connectors become stiff and can separate, and Che individual units will retain the roil curl until warmed to room temperature (aided by placement in sun for 15 to 20 minutes).
