Standard Specification for Type III Polymer Modified Asphalt Cement for Use in Pavement Construction (Withdrawn 2005)

SCOPE
1.1 This specification covers asphalt cements that have been modified by the addition of the appropriate polymer for use in pavement construction. It was developed to provide a reference for specifying polymer modified asphalt and reflects the properties of currently available commercial products. The tests are intended to measure compatibility and degree of modification, not performance characteristics. This is not intended to be a performance based specification.  
1.2 Type III polymer-modified asphalts are typically made with ethyl vinyl acetate. However any polymer may be used that will give the required test results when blended with the desired asphalt.  
1.3 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.
WITHDRAWN RATIONALE
This specification covers asphalt cements that have been modified by the addition of the appropriate polymer for use in pavement construction. It was developed to provide a reference for specifying polymer modified asphalt and reflects the properties of currently available commercial products. The tests are intended to measure compatibility and degree of modification, not performance characteristics. This is not intended to be a performance based specification.
Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this specification was withdrawn in June 2005 due to lack of use.
