AS 1141.66-2012

Scope

This Standard sets out a method for determining the methylene blue adsorption value
(MBV) for fine aggregate and mineral fillers.
This method applies to aggregate of less than 5 mm nominal size and may be used for both
natural and manufactured sands. The application of the test to slag, other artificial
aggregate or to recycled aggregate has not been evaluated. The method tests the passing
75 ìm fraction of a laboratory dried, unwashed fine aggregate sample.
For mineral fillers for asphalt, the test may be applied to fillers from bag house fines or
from ground limestone products or to mixtures of these two materials. The test is not
suitable for cement or fly ash fillers, as, by definition, mineral fillers are 90% or more
passing the 75 ìm sieve. The test applies to the total sample of mineral filler and not to a
test portion.
This Standard was developed from the International Slurry Surfacing Association (ISSA)
Technical Bulletin No. 145, Test method for the Determination of Methylene Blue
Adsorption Value (MBV) of Mineral Aggregate Fillers and Fines, proposed February 1989,
1st Revision 2005 and as modified by the Ohio Department of Transport with respect to
solution concentration (also known as the AASHTO T330-2007 method).
