ADDITIONAL INFORMATION

The EN 12697-12 Determination of water sensitivity of bituminous specimens, and EN 12697-23 Determination of the indirect tensile strength of bituminous specimens, require a typical Marshall tester fit with the Indirect tensile test accessories (see 76-B0078/B and 76-B0078/C devices), capable of producing a test graph.
EN 12697-34 Marshall test, correspond to the ASTM/AASHTO standards but, as the above, a test graph is required.

AASHTO T283-03 Resistance of compacted asphalt mixtures to moisture-induced damage can also be performed with the Marshall tester fit with the accessories 76-B0078/B or 76-B0078/C devices.

The Marshall/Indirect tensile testers fully satisfy this requirement as they are fit with the Digimax Touch data acquisition and processing system which can be connected to a PC and printer to produce a test graph and test certificate.

For the determinations of the EN 12697-12, EN 12697-23 and AASHTO T283 standards, as specified, the machine has to be used with the accessories 76-B0078/B, 76-B0078/C Tensile splitting devices (see accessories) while, for the EN 12697-34 and all ASTM/AASHTO standards, the machine has to be used with the 76-B0033 or 76-B0033/C stability moulds.
