AS/NZS 2341.23:2002 (R2013) PDF Download

The AS/NZS 2341.23:2002 (R2013) standard provides a standardized procedure for determining the residue from evaporation of bitumen emulsion. This method ensures consistency and reliability in measuring the residue left behind after evaporation.

The standard outlines the detailed steps to be followed for conducting the test. It specifies the necessary equipment and materials required, such as a standard aluminum dish, a suitable drying oven, and an analytical balance. The test involves carefully weighing a sample of the bitumen emulsion, placing it in the aluminum dish, and subjecting it to controlled evaporation in the drying oven.

Once the evaporation process is complete, the residue remaining in the dish is weighed using the analytical balance. This measurement provides an indication of the amount of solid material present in the bitumen emulsion after evaporation. By following the prescribed method, the standard ensures that consistent and accurate results can be obtained, allowing for comparisons between different samples and ensuring quality control in bitumen and roadmaking products.
