972-1 Description.
Recycled plastic products shall include certified test reports from an approved independent test laboratory that shows the material meets all specifications herein and the manufacturer shall certify the following:
972-2 Definitions.
972-2.1 Recycled Plastic: Those plastics composed of post -consumer material or
recovered industrial material only, or both, that may or may not have been subjected to additional processing steps designed to afford products such as regrind or reprocessed or reconstituted plastics.
972-2.2 Post-Consumer Materials: Those products genera ted by a business or consumer
that have served their intended end use and that have since been separated or diverted from solid waste for the purpose of collection, recycling, and re -disposition.
972-2.3 Recovered Material: Materials and by -products that have been recovered or
diverted from solid waste, but not including those materials and by -products generated from, and commonly used within, an original manufacturing process.
972-3 Materials.
The materials used for recycled plastic products shall consis t of a minimum of 70% by weight of recycled plastic. The products shall exhibit good workmanship and shall be free of burns, discoloration, contamination, and other objectionable marks or defects which affect appearance or serviceability. Only chemicals, i ncluding fillers and colorants, designed to inhibit photo degradation, biological/biochemical decomposition, insect infestation, or burning will be permitted to enhance durability. The use of sufficient additives to inhibit photo degradation over the lifetime of the product is required.
972-4 Sampling.
One additional product per 1,000, or a minimum of one per order shall be included in the order for Department testing. FY 2023-24 Return to Table of Contents SECTION 973 FIBER REINFORCED POLYMER (FRP) COMPOSITE STRUCTURAL SHAPES
973-1 Description.
This Section covers material and fabrication requirements for fiber reinforced polymer (FRP) composite structural shapes .
973-2 Product Acceptance.
Obtain FRP composites from a producer that is currently on the Department’s Production Facility Listing. Producers seeking inclusion on the list shall meet the requirements of Section 105.
973-3 Thermoset Pultruded Structural Shapes.
Thermose t pultruded structural shapes must meet the requirements in the materials section of the ASCE, Pre-Standard for Load & Resistance Factor Design (LRFD) of Pultruded Fiber Reinforced Polymer (FRP) Structures . Manufactured components shall be inspected accor ding to ASTM D3917 for dimensional tolerances and ASTM D4385 for visual defects. Pultruded profiles located on bridge and overhead sign structures shall meet a flame spread index of Class B in accordance with ASTM E84 and meet the requirements of UL94 wit h a rating of V -1.
973-4 Vacuum Infusion Processed (VIP) Structural Shapes .
973-4.1 Materials:
973-4.1 1 Fibers: Use commercial grade glass fibers that conform to
ASTM D578. Glass fibers may be in any form such as rovings, woven fabrics, braided fabrics, stitched fabrics, continuous fiber mats, continuous strand mats, continuous filament mats (CFM), and chopped stran d mats (CSM) of any size or weight. Each structural element shall contain a minimum of 40% (by weight) of glass fibers oriented in a minimum of two directions in accordance with the manufacturer’s requirements . Tensile strength of glass fiber strands, yarns and rovings shall not be less than 290 ksi in accordance with ASTM D7290, determined by a tension test in accordance with ASTM D2343.
973-4.1 2 Resin: Use a commercial grade thermoset resin for fabricating shapes.
973-4.1 3 Additives: Additives such as fillers, promoters, accelerators, inhibitors,
UV agents, and pigments, used in the processing or curing shall be compatible with the fiber and resin.
973-4.2 Physical and Mechanical Properties: The physical properties of VIP FRP
products shall conform to the requirements of Table 973-1. The characteristic mechanical properties of VIP FRP composite structural members, determined in accordance with ASTM D7290, shall equal or exceed the minimum requirements in Table 973-2 for shapes and Table 973-3 for plates.
