(4) Wherever in the Specifications the word "purchaser" appears it shall be taken to mean the Department. Acceptance of reinforcing steel shall be based on test samples taken randomly by the Department and manufacturer ' s certified mill analysis of test results meeting the specification limits of the ASTM or AASHTO designation for the particular size , grade and any additional requirements . Randomly taken test samples and certification of test values , representing each production LOT of reinforcing steel , shall be provided to the Engineer for each Contract prior to use . Randomly taken test samples shall be cut from bundled steel that is shipped to the jobsite . 932 NONMETALLIC ACCESSORY MATERIALS FOR CONCRETE PAVEMENT AND CONCRETE STRUCTURES . (REV 8-240) (FA 84240) (141 ) SUBARTICLE 9324 . 2 . 2 (Page 878 ) is deleted and the following substituted : 9324 . 2 .2 Material : The joint sealant shall be composed of a mixture of materials , typically but not limited to bituminous based, that will melt when heated for application and then solidify to form a resilient and adhesive compound capable of sealing joints in portland cement concrete and/or asphaltic concrete against the infiltration of moisture and foreign materials throughout normal pavement conditions and at ambient temperatures . The manufacturer shall have the option of formulating the material according to their Specifications . e However, the requirements delineated in this Specification shall apply regardless of the type of formulation used. The material shall cure sufficiently to not flow from the joint or be picked up by vehicle tires after 3 hours at 77 ° F . The material shall be capable of a uniform application consistency suitable for filling joints without the inclusion of large air holes or discontinuities and without damage to the material . Materials for pavement joints shall be tested according to ASTM D 5329 . 9324 . 2 . 2 . 1 Physical Requirements of Joint Sealants for Portland Cement Concrete Only : Parameter Limits Pour Point At least 20 °F lower than the safe heating temperature as stated y the manufacturer. Cone-Penetration, Non- Less than or equal to 90 mm immersed at 77 ° F , 150 g, 5 s Flow at 40 ° F , 5 h Less than orequal to 5 . 0 mm Bond, Non- immersed, 0 ° F for 5 No cracking, separation , or opening that at any point is over cycles * 1 /4 inch deep , in the sealant or between the sealant and the substrate . *The depth of a crack, separation or opening shall be measured perpendicular to the side of the sealant showing the defect. At east two test samples in a group of three representing a given sample of sealant shall meet this requirement. 932 - 1 . 2 . 2 . 2 Physical Requirements of Joint Sealants for Portland Cement Concrete and/or Asphaltic Concrete . -213 - FPID ( S ) : 4231864 - 58 - 01
