AS 2341.30:2021 pdf free download – Methods of testing bitumen and relatedroadmaking products Method 30:Recovery of residue from bituminous emulsion.
The water phase of a bituminous emulsion is evaporated from a weighed sample on a hotplate to recover the binder phase for further testing. The test is carried out under an inert atmosphere to minimize binder hardening during evaporation.
This method is applicable to bituminous emulsions used In the construction and maintenance of pavements (as specified in AS 1160).
This method may also be used to dctcrmirw the residue from evaporation of a bituminous emulsion, if specified.
2 Scope
This document sets out a procedure for the recovery of the residue from a bituminous emulsion for further testing. It also provides a means by which the residue from evaporation of a bituminous emulsion can be determined.

The following criteria should be used for judging the acceptability of residue from evaporation resultsobtained using this test ([95 % probability):
(a) Repeatability Duplicate results by the same operator should not be considered suspect unlessthey differ by more than 0.4 % mass.
(b) Reproducibility The results submitted by each of two laboratories should not be consideredsuspect unless the two results differ by more than 1.0 % mass.
