SET C – Covers A7 and A8 of TMH1

• 3001-GR30:06 The Determination of the maximum dry density and optimum moisture content of graded materials.

• 3001-GR31:06 The Determination of the California Bearing Ratio of graded materials.


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-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 DOCUMENTSTMH 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 2

• 3001-CO1 Mixing in the laboratory, sampling of freshly mixed concrete, casting and curing of test specimens.

• 3001-CO2 Consistency of freshly mixed concrete – the determination of the slump.

• 3001-C10 Dimensions, tolerances and uses of cast test specimens.

• 3001-C11 Compressive strength of matured concrete.

• 3001-PR10 The handling, maintenance and sieving techniques for test sieves. **

** Needs to be given priority as it is required as a normative reference for methods in Pilot Stage.


SET 3

First drafts have been submitted by SABITA to their members for comment.

MTC had a meeting in January 2008 with SABITA regarding these test methods.

• 3001-AS1 Making of briquettes for Marshall tests

• 3001-AS2 The determination of Marshall flow and stability

• 3001-AS10 The determination of bulk relative density and void content of compacted asphalt
