Anotace

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.
