AS 5101.2.2:2008 (R2017) PDF Download

The AS 5101.2.2:2008 (R2017) standard provides guidelines for the preparation and testing of stabilized pavement materials. It focuses specifically on the sampling and preparation of these materials using cementitious stabilizing binders such as lime, blended lime mixtures, cement, blended cements, bituminous, or other appropriate materials.

The standard outlines that the laboratory addition of these stabilizing binders should be performed in a controlled manner before conducting relevant test methods. The size fraction of the material to be prepared depends on the specific test to be performed on the stabilized material. For unconfined compressive strength tests and California bearing ratio tests, the fraction used should be that which passes through the 19.0 mm sieve.

The standard also highlights that the binders typically used for stabilized pavements are covered by separate standards, namely AS 1672.1 for limes, AS 3972 for cements, and AS 1160 and AS 2157 for bitumens.
