Kasch Park Soccer Fields Addendum No. 01 Synthetic Turf Replacement Phase 2 March 1, 2016 3. Single Layer Installation: The paved-in-place (in-situ)elastic layer shall be installed in one lift to a minimum thickness of 25mm. The elastic layer shall contain only the following: Components % by Weight Granulated SBR rubber(1-5mm) 43-47% Clean-washed "bird's-eye" aggregate (3-6mm) 44-48% Single component high quality polyurethane binder 6-8% 4. The exact material mix ratio may be altered to provide strength, shock attenuation (in conformance with the 110G limit specified herein)and to provide permeability as approved by the Engineer. Successful bidder may submit an elastic layer formulation with minor modification for Engineer's consideration and approval. 2. Section 32 18 23 Infilled Synthetic Turf ADD Section 3.02 B as follows: B. Elastic Layer Pad Installation 1. The Superintendent shall thoroughly inspect all materials delivered to site both for quality and quantity to assure that the entire installation shall have sufficient material to maintain proper mixing ratios. 2. Installation of the elastic layer shall not take place if the ambient temperature is below 50 degrees F,if the material is wet, or if rain is falling or pending. 3. The material to be placed shall be mechanically mixed to obtain a homogeneous mixture. Extreme care shall be taken under the immediate supervision of the Superintendent in the weighing and mixing of the components to maintain a uniform mixture with predicable and consistent performance characteristics across the entire field area. The polyurethane shall be of sufficient volume to obtain satisfactory long-term bonding of the components but shall not be of such volume as to render the elastic layer hard and uncomfortable for athletic use. 4. The elastic layer shall be installed with a paving machine that utilizes an electrically heated finish surface screed bar. The paving machine must be operated by a minimum of two skilled technicians at all times. 5. All seams shall be hand rolled and cold pad joints shall be primed with a polyurethane primer supplied by the binder manufacturer. 6. The Superintendent must consistently monitor thickness of the elastic layer and supervise all mixing ratios by means of component weight checks. 7. The elastic layer pad must cure free of foot and equipment traffic for 48 hours after placement. 8. The finished elastic layer must be properly compacted, uniform in texture, 3
