Scope

This European Standard specifies a method for the quantitative determination of recovered binder and oil distillate in bitumen emulsions composed principally of a semisolid or liquid bituminous base, water and an emulsifying agent.

The method can be used for the quantitative determination of recovered binder and oil distillate in bitumen emulsions for specification acceptance, service evaluation, control and research. The method can also be used to obtain residue and oil distillate for further testing.

NOTE 1. The properties of the material recovered in the test are not necessarily the same as those of the original materials from which the emulsion was produced, especially for polymer modified bitumens.

NOTE 2. The method described recovers only oil distillate as defined in 3.1.

NOTE 3. In the case of delay of distillation during testing of polymer modified bitumen emulsions, the test method shoudl be used in accordance with prEI 13074 : 1997 (IP 493)
