1 AS 5101.2.2—2008 Australian Standard® A S Methods for preparation and testing of stabilized 5 1 0 1 materials . 2 . 2 — Method 2.2: Sampling—Preparation of stabilized 2 0 0 8 pavement materials 1 SCOPE This Standard sets out the method for the addition in the laboratory of cementitious stabilizing binders such as lime, blended lime mixtures, cement, blended cements, bituminous or other materials to soils, gravels and crushed rock pavement materials, in preparation for use in an appropriate test method. The size fraction of the material to be prepared will depend on the test to be performed on the stabilized material. For unconfined compressive strength tests and California bearing ratio tests, the fraction used has to be that passing the 19.0 mm sieve. NOTE: The binders usually used for stabilized pavements are covered by the following Standards: (a) Limes, AS 1672.1. (b) Cements, AS 3972. (c) Bitumens, AS 1160 and AS 2157. 2 REFERENCED DOCUMENTS The following Standards are referred to in this Standard.
