For the purposes of this document, the following term and definition applies.
fines mixing time
time in seconds for the mixability of a mixture of mineral filler and bitumen emulsion without noticeable breaking effect under the conditions specified in this standard.
A specified quantity of filler is added at a uniform rate, with stirring, to a specified quantity of bitumen emulsion diluted with water. Stirring is continued until the mixture becomes pasty and forms lumps which do not adhere to the walls of the pan. This, combined with a noticeable increase in stirring power indicates the end of mixability. The time to reach this point (breaking status) is the fines mixing time.
Use only reagents of recognized analytical grade and water conforming to grade 3 of EN ISO 3696.
Carry out the procedure under normal laboratory conditions (18°C to 28 °C).
Dry the quantities of fller, required for the test, in the oven (6.1) at a temperature of (110土5) °C until constant mass is reached and let it cool to ambient temperature in a dessiccator.BS EN 13075-2 pdf download.
