702.01 Asphalt Binders.

General. According to AASHTO M 320 -10 Table 1 except as follows. Ensure PG 70 -22M, PG 76 -22M, PG 88 -22M, and PG 64 -28 meet the requirements of Table 702.01 -1. An independent laboratory will not be owned or operated, in whole or part, by the binder supplier, Contractor, or affiliates of either. Materials and Manufactur e. Replace the requirements of AASHTO M 320 -10 Table 1 Section 5 “Materials and Manufacture” Section with the following: 5.1 Supply PG Binder from the refining of crude petroleum, or combination of asphalt binders from the refining of crude petroleum, or asphalt binders and suitable liquid from the refining of crude petroleum, and possible organic modifiers for performance enhancement. Material from the crude refining stream is considered neat. Liquid from crude refining may be used for adjustments, but do not used liquid from crude refining for the purpose of substitution of crude refined asphalt binder in a PG Binder. In the event of a failure investigation where asphalt binders exhibit 702.01 716 unusual properties a supplier may be requested by OMM to supply i nformation about the makeup of a PG Binder. Failure to cooperate will mean removal from Supplement 1032 certification. 5.2 A modifier may be any approved material of suitable manufacture that is proven compatible with asphalt binder (does not separate app reciably in routine storage), and that is dissolved or reacted in asphalt binder to improve its performance. Performance enhancement is defined as a decrease in the temperature susceptibility of the asphalt binder while maintaining or improving desirable properties in a neat asphalt binder such as coat ability, adhesiveness and cohesiveness. Unless otherwise noted limit modifiers to no more than 6.0 percent by PG Binder weight. 5.3 The use of previously used materials in a PG Binder must be approved by OMM. Since no standard test procedures exist for reprocessed materials (and original tests were not developed with the use of such materials in mind), appropriate test methods may be chosen by OMM for review. OMM approval does not relieve the binder suppl ier from full responsibility for content and use of any previously used material in a PG Binder nor guarantee suitable performance enhancement as defined above. The detected presence in a PG Binder sample of any unapproved previously used material will me an immediate removal from Supplement 1032 certification. Limit approved previously used materials to 5.0 percent by PG Binder weight maximum and provide a written certification to OMM stating the exact percent used, the source, and any brand or trade names. Approved previously used materials are only allowed to be used to produce PG 58 -28 and PG 64 -28 and suppliers must get recertified per Supplement 1032 for these PG grades . 5.4 Ensure the PG Binder is homogeneous, free from water and delet erious materials, and does not foam when heated to 350 ºF (175 ºC). Prove the asphalt binder (before modification or after modification if liquid modifier used) is fully compatible with a negative result by means of the Spot Test per AASHTO T 102 using st andard naphtha solvent. If standard naphtha shows a positive result, a retest using reagent grade 35 percent Xylene/ 65 percent Heptane (volume) may be used. 5.5 Ensure the PG Binder is at least 99.0 percent soluble as determined by AASHTO T44 or ASTM D7553. Ensure any insoluble component is free of fibers or discrete particles more than 75 µm. 5.6 Ensure flash point is 500 ºF (260 ºC) minimum. Ensure mass change on RTFO of the final PG Binder grade is 0.75 percent maximum. 5.7 Ensure that PG 64 -22 has a Penetration (AASHTO T49) of no more than 77. 5.8 Direct Tension testing is not required, unless otherwise required in this specification. Requirements for PG Modified Binder. Furnish PG Modified Binder according to the requirements of Table 702.01 -1 by modifying a non -oxidized, non -air blown, neat asphalt binder by using a styrene butadiene latex rubber compound (SBR polymer), a styrene butadiene styrene polymer block copolymer (SB, SBS polymer), an ethylene/ nbutyl acrylate/ glycidyl methacrylate co polymer (Elvaloy) as specified or Ground Tire Rubber (GTR) according to Supplemental Specification 887. For SB, SBS products the polymer supplier will certify to the refiner and Contractor that the polymer used meets a minimum 68 percent by weight butadie ne content. Perform SB, SBS, Elvaloy or GTR modification prior to shipment to the asphalt concrete mixing plant (pre -blend). Perform SBR modification at the asphalt 702.01 717 concrete mixing plant (post -blend) or prior to shipment to the asphalt concrete mixing p lant (pre -blend) where allowed by specification. Polyphosphoric acid (PPA) is allowed in PG binders as follows. PPA is a polymer of orthophosphoric acid. When using PPA ensure all the applicable requirements of the required PG binder in Table 702.01 -1 are met. Ensure PPA does not contain water. To retain Supplement 1032 certification, suppliers of PPA modified asphalt will provide a written certification to OMM that the amount of PPA used is less than 1.0% by weight of neat binder. Suppliers of PPA can ha ve their Supplement 1032 certification removed for not following the above PPA requirements. For each project, the PG Modified Binder supplier will give the Contractor a handling guide specifying temperature, circulation, shelf life, and other requiremen ts for assuring the PG Modified Binder will perform as desired. Give this handling guide to the Monitoring Team and place a copy in the plant control room and plant laboratory. If PG Modified Binder is retained at the asphalt concrete mixing plant for mo re than two weeks before use or beyond the supplier recommended shelf life, whichever is less, a top and bottom sample test (material property difference between samples taken from the top and bottom of the storage tank) will be performed by OMM on samples retrieved by the Contractor at the Laboratory’s direction. Do not use material on hand until approved.
