ASTM D5840-00 PDF Download

The ASTM D5840-00 standard specifies the requirements for asphalt cements that have been modified with an appropriate polymer for use in pavement construction. The purpose of this standard is to provide a reference for specifying polymer modified asphalt and to reflect the properties of currently available commercial products.

The standard includes tests that measure the compatibility and degree of modification of the asphalt cement, rather than evaluating its performance characteristics. It is important to note that this specification is not intended to be performance-based.

Specifically, the Type II polymer-modified asphalts covered by this standard are commonly made with either styrene-butadiene rubber latex or polychloroprene latex. However, any polymer can be used as long as it meets the required test results when blended with the desired asphalt.
