3、 July 2010.1. Scope1.1 This specification covers cutback petroleum asphalts ofthe slow-curing type for use in the construction and treatmentof pavements.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. Thevalues stated in each system may no

4、t be exact equivalents;therefore, each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.2.
