ASTM D8 defines many terms common to asphalt cement. 3.1.2. asphalt binderan asphalt-based cement that is pro
9、duced 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., SP
10、G 67-19 or SPG 73-25). 5. MATERIALS 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
11、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 175C. 5.4. The asphalt binder must be at least 99.0 percent soluble, when determined in
12、accordance with T44, ASTM D5546, or ASTM D7553. 5.5. This specification is not applicable to asphalt binders in which fibers or other discrete particles are larger than 250 m in size. 5.6. The grades of asphalt binder must conform to the requirements given in Table 1. 6. SAMPLING 6.1. Sampling will
13、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, or ASTM D5546, T 48, T 55, T 313, T 315, T 316, and ASTM D7553. 8. INSPECTION AND CERTIFICATION 8.1. Inspection and certification of the material wi
14、ll 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. 2018 by the American Association of State Highway and Transportation
