This European Standard specifies a method for visualisation of the polymer distribution in a polymer modified bitumen by fluorescent microscopy.

The method is applicable for most of the commercially used polymers, but before the method is used it should be examined whether the test is applicable for the actual polymer.

The method should only be used for identification purposes, i.e. in connection with production control.

NOTE Sample preparation and treatment have an important influence on the test results and it is essential to follow strictly the method described to achieve comparable results.
