, . ., -, RECYCLING AGENTS Recycling Agent Minimum/Maximum Test Conditions Value Viscosity -P (Pa's) 1400F [600C] Target Viscosity ::!: 20% Viscosity Ratio Visco 1400F [600C] after TFOT (Residue from Thin Film Visco 1400F [600C] before TFOT maximum 3 Oven Test) Smoke Point COC minimum 2600F [125OC] Flash Point COC minimum 4000F [205OC] Solubility in Trichlorethylene minimum 97.5% . ..., . . II . .., . , Rack blending of recycling agents (blending from two RA tank sources) will be permitted to meet a required target viscosity value. Silicone shall be added to the recycling agent at a rate of 25 cm3 for each 5,000 gallons [19 m3] of recycling agent. If a dispersing fluid is used in conjunction with the silicone, the resultant mixture containing the full 25 cm3 shall be added, in accordance with the manufacturer's recommendation. The blending of silicone mixture with the residue shall be done by the supplier prior to shipment. The recycling agent shall contain 0.5% heat-stable anti-strip additive by weight of asphalt from an approved source. The anti-strip additive shall meet the requirements of 916-5. The anti-strip additive shall be introduced and mixed into the recycling agent at the terminal. Where a recycling agent is used in mixes containing reclaimed asphalt pavement (RAP), the requirements of 334-2.3.4 must also be met. 916-2.2 Sampling and Reporting: Sampling of recycling agents shall be done in accordance with AASHTO T-40. Initial Specification Compliance test results shall be required for each new LOT of material. A new LOT will occur when the material in a tank changes and the Specification Compliance Test may not be representative of the material in the tank. This may be due to an incoming bulk shipment of material, change in refinery run, the manufacture of a product, or a blend of material in a tank. A monthly report by the supplier containing Specification Compliance Test results for each RA LOT shall be submitted by the supplier in electronic format using the form provided by the Department to the State Materials Office within seven days following the end of the calendar month. Copies of these monthly reports and supporting test reports shall be available at the supply location for a minimum of three years. 916-2.3 Certification and Verification: The supplier shall furnish certification on the bill of lading for each shipment of recycling agent delivered to a Department project that includes: the quantity, the RA target viscosity, the RA LOT(s), a statement that the RA is in conformance with 916-2, and the quantity of silicone and anti-strip agent addition, including product designation (QPL number as applicable). The Department may sample and test recycling agents from the suppliers storage tank, the delivery vehicle, and/or Contractors storage tank to verify and determine compliance with this and other specification requirements. Where these tests identify material outside specification requirements, the State Materials Engineer may require the supplier to cease shipment of RA binder from that RA LOT(s). Further shipment of RA binder from that RA LOT(s) to Department projects may remain suspended until the cause ., . -, . ., . ~ . -, . ..... . .., . ~1 . ., . ..... . . n . -, 09/09 01 000-1 67 03-4122.F .
