AS 2341.9:1992 standard "Methods of testing bitumen and related roadmaking products - Determination of water content (Dean and Stark)" provides a specific procedure for determining the water content of bituminous materials. It is applicable to road tars and bituminous emulsions.

The method described in this standard utilizes the Dean and Stark apparatus, which is commonly used for the separation and quantification of water from organic compounds. The procedure involves the addition of a specified quantity of the bituminous material to the apparatus, along with a suitable solvent.

The mixture is then subjected to heat and distillation, allowing the water content to separate from the bituminous material and dissolve into the solvent. The water is collected in a graduated receiver tube and measured.

By following this standardized procedure, one can accurately determine the water content of bituminous materials, which is crucial for assessing their quality and performance in roadmaking applications.
