3. TERMINOL .OGY 3.1. Definittions: 3.1.1. ASTM D8 defines many terms common to asphalt cement. 3.1.2. asphalt binder- an asphalt-based cement that is produced from petroleum residue either with or without the addition of non-particulate, non-fibrous organic modifiers. 4. ORDERING INFORMATION 4.1. When ordering under this specification, include in the purchase order the surface performance grade (SPG) of asphalt binder required from Table 1 (e.g., SPG 67-19 or SPG 73-25). 5. MATERIAL .S AND MANUFACTURE 5.1. Asphalt binder must be prepared by the refining of crude petroleum by suitable methods, with or without the addition of modifiers. 5.2. Modifiers may be any organic material of suitable manufacture that is used in virgin or recycled condition and that is dissolved, dispersed, or reacted in asphalt binder to enhance its performance. 5.3. The asphalt binder must be homogeneous, free from water and deleterious materials, and must not foam when heated to 175°C. 5.4. The asphalt binder must be at least 99.0 percent soluble, when determined in accordance with T 44 or ASTM D7553.5.5. This specification is not applicable to asphalt binders in which fibers or other discrete particles are larger than 250 um in size. 5.6. The grades of asphalt binder must conform to the requirements given in Table l. 6. SAMPLING 6.1. Sampling will be in accordance with R 66. 7. TEST METHODS 7.1. The properties outlined in Sections 5.3, 5.4, and 5.6 must be determined in accordance with R 28, T44,T48,, T313,T315, T 316, ASTM D95, and ASTM D7553. 8. INSPECTION AND CERTIFICATION 8.1. Inspection and certification of the material will be as agreed upon between the purchaser and the seller. Specific requirements must be made part of the purchase contract. The seller will provide material handling and storage procedures for each asphalt binder grade certified.9. REJECTION AND RETESTING 9.1. If the results of any test do not conform to the requirements of this specification, retesting to determine conformity is performed as indicated in the purchase order or as otherwise agreed upon between the purchaser and the seller. 10.
