Bituminous Mixtures - Test Methods - Part 18: Binder Drainage
Also Known As:
The DIN EN 12697-18 standard describes two test methods: the basket method and the beaker method.
The basket method is used to determine the binder drainage of bituminous mixtures. This method directly measures the drainage of the binder, but it may encounter some limitations when used on mixtures with fibres or higher mortar content, as these can cause clogging of the drainage baskets. The basket method can be employed to determine binder drainage for different binder contents or with a single binder content, thereby eliminating the need for repeated measurements. It also allows for the evaluation of the effects of varying fine aggregate types or the inclusion of any anti-draining additives.
The beaker method, on the other hand, is used for determining the binder drainage of bituminous mixtures that are not porous asphalt or for porous asphalt mixtures that incorporate fibers. Similar to the basket method, it can be used to measure binder drainage for different binder contents or with a single binder content. Additionally, it enables the quantification of the effects of varying fine aggregate types or the inclusion of any anti-draining additives.
