2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers asphalt cementbinder for use in the construction of pavements
3、.NOTE 1For asphalt binders graded by viscosity at 60C, see Specification D3381. For performance-graded asphalt binder, see Specification D6373.1.2 This specification covers the following penetration grades:4050, 120150, and6070, 200300.85100,1.3 The values stated in either SI units or inch-pound uni
4、ts are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.2. Referenced Documents2.1 ASTM Standards:

7、 BinderD7553 Test Method for Solubility of Asphalt Materials in N-Propyl Bromide3. Manufacture3.1 Asphalt cementbinder shall be prepared by the refining of crude petroleum by suitable methods.4. Properties4.1 The asphalt cementbinder shall be homogeneous and shall not foam when heated to 175C 350F.4
8、.2 The asphalt cementbinder shall conform to the requirements given in Table 1 or Table 2, as specified by the purchaser. Ifno table is specified, the default shall be Table 1. Table 2 requirements limit the temperature susceptibility of asphalt over Table1 requirements. Asphalts Asphalt binders tha
9、t meet Table 2 requirements will also meet Table 1 requirements of the same grade.5. Methods of Sampling and Testing5.1 The material shall be sampled and the properties enumerated in this specification shall be determined in accordance withthe following ASTM methods:1 This specification is under the
