4 Test methods
4.1 Principle
The test consists of compacting an asphalt layer of a determined composition on a bitumen sheet laid on a base specimen.
It may be carried out in two alternative ways:
– -。 Method 1: The asphalt layer is laid directly on the sheet bonded to the base specimen;
-Method 2: A de-bonding interface is laid between the base specimen and the sheet and between the sheet and the asphalt layer.
After compacting of the test specimen, the bitumen sheet is recovered for observation of its condition and any perforations. Depending on the results of the observations, the watertightness of therecovered bitumen sheet should be checked.
