TMH AND TRH DOCUMENTS
 The production of essential normative reference methods
which are being done in the next phase were needed before
SABS can publish Sets A to C.
 Work on next phase (Sets 1 to 5) is progressing well
SET 1
• 3001-AG1 The particle size analysis of aggregates by sieving. **
• 3001-AG3 The determination of the flakiness index of coarse aggregate.
• 3001-AG10 Aggregate crushing value of coarse aggregates.
• 3001-AG11 FACT value (10% fines aggregate crushing value) of coarse
aggregates.
• 3001-AG20 The determination of the dry bulk density, apparent relative density
and water absorption of material retained on the 5mm sieve.
• 3001-AG21 The determination of the dry bulk density, apparent relative density
and water absorption of material passing the 5mm sieve.
** Needs to be given priority as it is required as a normative reference for methods in
Pilot Stage.
TMH AND TRH DOCUMENTS
SET 2
• 3001-GR31 The determination of the maximum dry density and optimum moisture
content of laboratory mixed stabilized graded materials.
