ASTM D5976-00 PDF Download

The ASTM D5976-00 standard provides specifications for asphalt cements that have been modified with an appropriate polymer for use in pavement construction. This standard serves as a reference for specifying polymer-modified asphalt and reflects the properties of currently available commercial products. It is important to note that this specification is not intended to be a performance-based standard.

According to the specification, Type I polymer-modified asphalts are typically made with styrene-butadiene-styrene block copolymers, although other polymers may be used as long as they meet the required test results when blended with the desired asphalt. This ensures that the polymer modified asphalt meets the necessary performance requirements for use in pavement construction.
