916 BITUMINOUS MATERIALS . <br /> (REV 8440) (FA 84640) ( 141 ) <br /> SECTION 916 - 1 (Pages 828 - 842) is deleted and the following substituted : <br /> SECTION 916 <br /> BITUMINOUS MATERIALS <br /> 916- 1 Superpave PG Asphalt Binder : <br /> 9164 . 1 Requirements : Superpave Performance Graded (PG) asphalt binders , identified <br /> as PG 64 -22 , PG 67 -22 , and PG 76 -22 , shall meet the requirements of 916 - 1 . 2 , AASHTO M 320 <br /> Table 1 and the following additional requirements : <br /> 1 . The mass loss AASHTO T 240 shall be a maximum of 0 . 5 % for all grades . <br /> 2 . The intermediate test temperature at 10 rad/s . for the Dynamic Shear <br /> Rheometer test AASHTO T 315 shall be 25 °C for all grades . <br /> 3 . An additional high temperature grade of PG 67 is added for which the high test k , <br /> temperature at 10 rad/sec for the Dynamic Shear Rheometer test AASHTO T 315 shall be 67 °C . <br /> 4 . All PG asphalt binders having a high temperature designation of PG 67 or <br /> lower shall be prepared without modification . <br /> 5 . All PG asphalt binders having a high temperature designation higher than <br /> PG 67 shall be produced with a styrene-butadiene- styrene ( SBS ) or styrene-butadiene ( SB ) . ' <br /> elastomeric polymer modifier and resultant binder shall meet all requirements of this <br /> Specification ; in addition the phase angle at 76°C (AASHTO T 315 ) shall be a maximum of <br /> Li <br /> 75 degrees . t <br /> 6 . The maximum viscosity AASHTO T 202 shall be 2400 poises for PG 64 -22 <br /> and 3600 poises for PG 67 -22 . <br /> All hot mix asphalt (except hot mix asphalt containing 20 % RAP or greater) shall <br /> contain Superpave PG asphalt binder grade PG 67 -22 unless otherwise specified in the plans <br /> and/or Specifications for the hot mix asphalt product. <br /> For all PG binder used in all hot mix asphalt, silicone may be added to the PG <br /> binder at the rate of 25 cubic centimeters of silicone mixed to each 5 , 000 gallons of PG binder. If <br /> a disbursing fluid is used in conjunction with the silicone , the resultant mixture containing the <br /> full 25 cubic centimeters of silicone shall be added in accordance with the manufacturer ' s <br /> recommendation . The blending of the silicone with the PG binder shall be done by the supplier <br /> prior to the shipment . <br /> All PG binder and asphalt rubber binder for Friction Course mixes and for other <br /> hot mix asphalt products containing RAP shall contain 0 . 5 % heat stable anti - strip additive by <br /> weight of PG binder unless specifications for the hot mix asphalt product requires testing by <br /> FM 1 -T 283 and the test results indicate it is not required, or the mixture contains hydrated lime . <br /> Where FM 1 -T 283 indicates an anti - strip additive is required, it shall be from 0 . 25 to 0 . 75 % . <br /> The anti - strip additive shall meet the requirements of 916 - 5 . The anti - strip additive shall be <br /> introduced into the PG binder by the supplier during loading . <br /> Where PG binder is used in mixes containing reclaimed asphalt pavement (RAP) , <br /> the requirements of 334- 2 . 3 . 4 must also be met . <br /> 9164 . 2 Qualified Products List : The Superpave PG asphalt binders supplied under this <br /> Specification shall be one of the products included on the Qualified Products List as specified in <br /> 6 - 1 . Manufacturers seeking evaluation of their product shall submit an application in accordance <br /> -205 - <br /> FPID ( S ) : 4231864 - 58 - 01 <br />
