Joske EPDM…
Product Description
The Joske EPDM is a Paved in place Polyurethane and rubber running track system. The permeable running track system consists of (1) base primer, (2) EPDM rubber and Polyurethane shock mat, (3) Line Striping. What makes the Joske EPDM better than other systems in its class is the quality of materials and equipment used in the installation. The Joske EPDM 5/8î is the thickest polyurethane surface of its type. A.T.G. Sports only uses test proven materials and specific equipment designed for this specialized type of surfacing.
Materials
A) Polyurethane Pavement Primer - .35 lbs/yd
B) Industrial EPDM Rubber - 16.50 lbs/yd
C) Shock Mat Polyurethane - 4.0 lbs/yd
Installation
A) Pavement Inspection - Check pavement for any irregularities. All paved areas, which are to receive synthetic surfacing, shall be straight so as not to vary more than 1/8” when an 11’ straight edge is place over it. Minor irregularities (less than 3/16” in 11’) can be repaired with shock mat material at an extra cost. All areas designed to have more than 1/8” variance will not be paved. No fillers may be used to repair low areas.
High spots shall be ground off prior to installation of shock mat material. Asphaltic pavement must have cured at least 14 days prior to surfacing installation. Concrete surfacing shall have a minimum of 30 days cure time. All areas to be surfaced must be clean from dust or other matter prior to installation.
B) Primer - Polyurethane based Primer shall be applied to the pavement at a rate of .35 lbs per square yard. Primer shall be formulated to insure adhesion between the paving and the new polyurethane surfacing. Shock mat is to be installed within 24 hours of applying primer.
C) Shock Mat - Prior to installing the Shock Mat, the paving shall be surveyed and marked so that all seems are within 2” of the nearest stripe. Start/Spots shall be place to fall under the nearest cross mark such as a finish line. Shock Mat is manufactured from Polyurethane Binder and Industrial grade rubber (black surface) The Polyurethane and rubber shall be mixed in a continuous mixer M-6000 at a ratio of 100 lb. EPDM rubber to 23 lb. of Polyurethane. Batch mixing will not be allowed. Shock mat shall be applied with sports paver specifically designed for running surfaces with a heated vibrating screed. Use of an SMG Plano Matic with 11’ screed shall insure seems fall within 2” from the center of the line stripe. Start/Stops should be place under the finish line nearest PC#1 and PC#3. If PC3# does not have a finish line, the Start/Stop shall be installed at the PC line. Minimum EPDM rubber is 16.5 lbs/yd. for 5/8” surface. Minimum Polyurethane is 23 parts per 100 parts of rubber. Industrial grade EPDM rubber granules processed to a size of between 1mm-3mm. free of fabric and foreign material. Recycled tire rubber will not be allowed. Moisture content shall not be more than 3%.
D) Temperature - Installation of surfacing shall be limited to ambient temperatures between 60 degrees and 100 degrees and surface temperature between 60 degrees and 105 degrees. For best results install when surface temperature is between 60 to 90 degrees.
