use the asphalt rubber binder in storage , and where applicable , stop all asphalt rubber blending operations at the project site or asphalt plant and solve the problem . Do not use asphalt rubber binder with low viscosity in mix and interlayer construction, or resume blending operations at the project site or asphalt plant until the Engineer grants approval . The Engineer may require that any mix and interlayer placed with low viscosity asphalt rubber binder be evaluated in accordance with 334 - 5 . 9 . 5 . In the event that the viscosity of the asphalt rubber binder increases to the extent that plant production or paving operations of the mix are adversely affected (i . e . density or texture problems occur) , stop plant operations and resolve the problem to the Engineer ' s satisfaction . 336-5 . 1 .2 Action at Supplier ' s Terminal : If the asphalt rubber binder does not meet the minimum viscosity requirement at the supplier ' s terminal, stop shipment and blending of asphalt rubber binder, and make the appropriate adjustments as necessary to meet the requirements of Table 3361 in order to ( 1 ) correct the viscosity of the blended material in the tank, and (2 ) correct the blending operation . Resume shipment and blending of asphalt rubber binder when a retest indicates the viscosity meets Specifications . Document actions taken in the Quality Control records . 336-5.2 Verification Requirements : The Engineer will test the asphalt rubber in accordance with FM 5 - 548 or AASHTO T 316 randomly on an as needed basis at the project site or asphalt plant, or the supplier ' s terminal to ensure conformance with the minimum viscosity requirement as specified in Table 3364 . 336-5 .2 . 1 Action at Project Site or Asphalt Plant : If the asphalt rubber binder does not meet the viscosity requirements at the project site or asphalt plant, stop use of asphalt rubber binder. Do not use asphalt rubber binder with a viscosity outside of the specified range in mix and interlayer construction until corrective actions , as necessary to meet the requirements of Table 3364 , have been made, verified by passing test results, and the Engineer grants approval . The Engineer may require that any mix and interlayer placed with an asphalt rubber binder with a viscosity outside of the specified range be evaluated in accordance with 334 - 5 . 9 . 5 . In the event that the viscosity of the asphalt rubber binder adversely affects plant production or paving operations , stop plant and paving operations and resolve the problem to the Engineer ' s satisfaction . 336-5 .2 . 2 Action at Supplier ' s Terminal : If the asphalt rubber binder does not meet the viscosity requirements at the supplier ' s terminal, stop shipment and blending of asphalt rubber binder until corrective actions are made to meet the requirements of Table 336 . 1 . 336-5 .3 Asphalt Rubber Binder Blending Quality Control Records : Maintain adequate Quality Control records for the Engineer ' s review of all blending activities . The Quality Control records shall include at a minimum the following information (for each batch of asphalt rubber binder produced) : asphalt rubber binder type, asphalt rubber binder batch quantity, asphalt binder supplier (including QPL number and LOT) , asphalt binder quantity in gallons , ground tire rubber supplier (including QPL number and LOT), ground tire rubber quantity in pounds , individual quantities of asphalt rubber binder shipped, financial project number, shipping date, customer name , delivery location, and viscosity test results . 336-5 .3 . 1 Additional Records for Blending at Project Site or Asphalt Plant : Monitor the ground tire rubber content in the asphalt rubber binder on a daily basis based on one of the following methods : 1 . Record the weight of the ground tire rubber used and the number of gallons of asphalt rubber binder produced. Calculate the percentage of rubber used and confirm - 100 - FPID (S ) : 423186A1 58 - 01
