19、ple After preparing flexible sheets of the polymer-modified bitumen emulsion, the specimens are placed in a refrigerated box at a defined low temperature for a period of at least 1 h 10 min. After that time the specimens are bent around the bending steel. 5 Apparatus 5.1 Refrigerated box, the temper
20、ature of which can be regulated between (-10 1) C and (+10 1) C (minimum range). 5.2 Mandrel according to EN ISO 1519 of wood or steel with a diameter of 30 mm (see Figure 1). 5.3 Foil (e.g. polyethylene) as a substrate for the application. 5.4 Frame or gauge.

To
22、provide the specified dry layer thickness the wet coating has to be levelled off with the aid of a frame or a gauge on the foil at room temperature as specified in the manufacturers instructions. The thickness of the wet layer shall be such that the dry layer is (3 0,3) mm. The preparation is to be
23、carried out without any reinforcement. The specimens shall then be stored in a standard climate of (23 2) C and a relative humidity of (50 5) % for 28 days in accordance with ISO 554. Remove the foil after 14 days. 8 Procedure After 28 days the test specimens shall be cut to the size specified in Cl
24、ause 6. The five specimens shall be placed in a refrigerated box with a temperature of (0 0,5) C with the madrel for a period of at least 1 h 5 min. Each specimen shall be bent with constant speed around the mandrel inside the refrigerated box for 3 s. 9 Expression of results and precision 9.1 Expre
