(Specification)Standard Specification for Chemically Modified Asphalt Cement for Use in Pavement Construction
Standard Specification for Chemically Modified Asphalt Cement for Use in Pavement Construction
ABSTRACT
This specification covers asphalt cements that have been modified by the addition of a chemical gellant. The asphalt cement used to prepare the chemically modified asphalt cement shall be prepared by the refining of crude petroleum by suitable methods. Chemically modified asphalt cements are normally produced by addition of a chemical stabilizer. However, any asphalt modifier may be used that will give the required test results when blended with the desired asphalt. Different test methods shall be performed in order to determine the following properties of the cement: penetration, viscosity, flash point using Cleveland open cup, solubility in trichloroethylene, softening point, residue from thin-film oven test.
SCOPE
1.1 This specification covers asphalt cements that have been modified by the addition of a chemical gellant. It was developed to provide a reference for specifying chemically modified asphalt cement and reflects the properties of currently available commercial products. The tests are intended to measure degree of modification not performance characteristics. This is not intended to be a performance–based specification.
1.2 Chemically modified asphalt cements are normally produced by addition of a chemical stabilizer. However, any asphalt modifier may be used that will give the required test results when blended with the desired asphalt.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 The following precautionary statement pertains to the test method portion only, Section 5, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
