Requirements for Polyester/Epoxy Resin SystemsThe following procedure is to be used in acquiring approval of Polyester/Epoxy Resin Systems: 1. The manufacturer/supplier will provide the Materials Division with a test report from a recognized laboratory covering the material to be used. The polyester/epoxy resin system will be tested in accordance with ASTM C 881/AASHTO M 235. A recognized laboratory is any State Highway Agency, Federal Highway Administration, or independent laboratory regularly inspected by the National Institute of Standards and Technology. Accompanying this report will be a statement by the manufacturer/supplier certifying compliance of the material with the requirements of ASTM C 881/AASHTO M 235 Type IV, Grades 2 or 3 (Viscosity, Consistency, and Volatile Content may not be applicable to polyester systems) and the suitability of the adhesive system for use in securing steel products to portland cement concrete (ASTM E 488, Single Anchor, Static Tension). The statement will also indicate the temperature Class(A, B, or C) that the material meets. If the material does not meet all the requirements of ASTM C 881/AASHTO M 235 (Type IV, Grades 2 or 3) the manufacturer/supplier will certify to only those requirements the materials meets and note those that it does not meet. Products not fully complying may be considered for and approved for specific or limited uses. 2. A sample of the system will be supplied to the Materials Division for testing. The sample should be sent to the Department and the Division at: Box 2261 or 11301 Baseline Road Little Rock, AR 72203 Little Rock, AR 72209 3. If the test report and AHTD tests indicate compliance with specifications, the product will be approved for use. 4. Destination samples will also be taken as deemed necessary to assure compliance with specifications. Failure of these samples may be considered sufficient cause to reject the material and suspend further use and/or removal from this QPL until tests by the Department determine that the producer's product is in compliance with applicable specifications and requirements. 07/2008 QPL 604.02 CONSTRUCTION RAISED PAVEMENT MARKERS(CRPM)

All reports shall include the manufacturer’s name, address, and name or model of marker. 2. The manufacturer shall submit a sample and product information, including printed instructions for application. 3. If the markers meet the performance criteria, a letter and unsigned certification agreement will be sent to the manufacturer. The product will be placed on the QPL upon receipt of the signed certification agreement. 4. Destination samples will be taken as deemed necessary by the Materials Engineer to assure compliance with specifications. 5. Failure of these samples either in the laboratory or in field applications is sufficient reason to reconsider acceptance of the material. Suspension of further use and/or removal from the QPL may occur until the Materials Engineer determines that the product is in compliance with applicable specifications and requirements. 07/2008 QPL 604.021 CONSTRUCTION CONCRETE BARRIER MARKERS
