Methods for sampling and testing aggregates; method 30.2: preparation of aggregate reference specimens for visual comparison

This Standard sets out the method for preparing reference specimens that represent each of the visually distinguishable rock types present in a quarried source for use in AS 1141.30.1. The reference materials are sampled on the basis of differences in colour, grain size, texture and grade of weathering, i.e. general appearance. Normally a set of reference specimens are prepared when a source is first sampled. Thereafter, additional reference specimens are prepared whenever previously unsampled materials are encountered in subsequent sampling. Reference specimens are not generally prepared for material that is obviously soft, friable or composed of clay. (a)
