702.01 Asphalt Binders.
General. According to AASHTO M 320-23 Table 1 and Supplement 1105 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 Manufacture. Replace the requirements of AASHTO M 320-23 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 enha ncement. 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 th e event of a failure investigation where asphalt binders exhibit unusual properties a supplier may be requested by OMM to supply information 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 appreciably in routine storage), and that is dissolved or reacted in asphalt binder to improve its performance. Do not use par affin wax, organic wax, or like materials. 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 supplier 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 mean immediate removal from Supplement 1032 certification. Do not use recycled engine oil bottoms (REOB), vacuum tower asphalt extender (VTAE), or like materials as modifiers. 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 deleterious 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 nega tive result by means of the Spot Test per AASHTO T 102 using standard 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 or ensure that the PG Binder meets a maximum of 1.0 percent ash content as determined by AASHTO T111. 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 PAV aged all PG grades at 212 ºF (100 ºC). 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 butadiene 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 concrete mixing plant (post-blend) or prior to shipment to the asphalt concrete mixing plant (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 have 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 requirements 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 more 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.

b.CRS-2P, test within 20 days of project sampling. Limits for both certified source and project samples.
c.CRS-1P and HFRS-1P, test within 20 days of project sampling. Limits for both certified source and project samples.
d.See Supplement 1013. For Type C if natural latex is used, use the Oven Evaporation method in AASHTO T 59 in place of distillation and use this residue for further testing.
e.Straight molds. Hold at test temperature for 90 minutes. Place in ductilometer and elongate 20 cm at 5 cm/min. Hold for 5 minutes and cut. After 1 hour retract the broken ends to touch and note elongation in cm (X) to the nearest 0.01cm. Percent Recov ery = ((20-X)/20) x 100. Report elastic recovery to nearest 0.1%.
f.SBR, SBS, & SB
g.Minimum of 70 SFS for project acceptance
h.CSS-1hM, test within 30 days of sampling. Limits for both certified source and project samples. Do not use port addition of the polymer to the emulsified asphalt. Include the percent residue on the Bill of Lading.
i.On base asphalt only
j.Effective January 1, 2027, the Rotational Paddle Viscometer (DPV) will be required for viscosity testing. Suppliers may use either the Saybolt Furol or DPV prior, however, the Saybolt Furol will be used for referee testing until January 1, 2027.
