1、Designation: D946/D946M 09aD946/D946M 15Standard Specification forPenetration-Graded Asphalt CementBinder for Use inPavement Construction1This standard is issued under the fixed designation D946/D946M; the number immediately following the designation indicates the yearof original adoption or, in the

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:
