ASTM D6154-15 PDF Download

The ASTM D6154-15 standard describes the requirements for chemically modified asphalt cements. These cements are prepared by refining crude petroleum using suitable methods.

The standard specifies that chemically modified asphalt cements are typically produced by adding a chemical stabilizer, although other asphalt modifiers may be used as long as they meet the required test results when blended with the desired asphalt. The tests conducted include measuring properties such as penetration, viscosity, flash point using the Cleveland open cup method, solubility in trichloroethylene, softening point, and residue from the thin-film oven test.

It is important to note that this standard is not intended to be a performance-based specification. Instead, it provides a reference for specifying chemically modified asphalt cement and reflects the properties of currently available commercial products. The tests outlined in the standard aim to measure the degree of modification rather than the performance characteristics of the asphalt cements.
