About Water In Bituminous Material (Dean-Stark
Specification:
A Water in Bituminous Material Dean-Stark spec refers to a standardized test method, like ASTM D95 or IS 1211:2022, that uses a Dean-Stark apparatus and distillation with a water-immiscible volatile solvent to determine the water content in bituminous materials such as asphalt and bitumen emulsions.The spec outlines the apparatus components and the procedures for conducting the test, collecting, and reporting the water volume from the distilled sample.
Key Components of the Apparatus
Distillation Flask: A glass flask (e.g., 500 ml) where the sample and solvent are heated.
Dean-Stark Apparatus: The condensing and collecting system, which includes a reflux condenser and a graduated receiver trap that separates the water from the solvent.
Electric Heater: A controlled heating device to provide consistent heat for distillation.
Support Stand and Clamps: To hold the flask, condenser, and receiver in place.
Test Method Overview
Sample Preparation:
A sample of the bituminous material and a water-immiscible volatile solvent are placed in the distillation flask.
Heating and Distillation:
The mixture is heated, and the solvent evaporates, rises, and condenses in the condenser.
Water Collection:
The condensed liquid flows into the Dean-Stark trap, where water, being denser, settles at the bottom, while the immiscible solvent overflows and returns to the flask.
Measurement:
The test continues until the volume of water in the trap remains constant.
Reporting:
The collected water's volume is measured from the graduated tube to determine the water content in the bituminous material.
