General description
General description
A bench mounted compression frame with motor and worm gear housed within the base unit producing a platen speed of 50.8 mm/min. A limit switch is provided for the bottom limit of travel. The machine is fit with a precision strain gauge load cell and displacement transducer, both connected to the Digimax Touch data acquisition and processing system (which is part of the system) featuring a large display and standard software covering either the Marshall or the Indirect tensile test. For more details see PC software.
The machine can be completed with a PC software (see accessories) suitable for running CBR, Marshall, Indirect Tensile and universal load/displacement tests. Data are presented numerically and graphically in real-time:
  • Saving and management of tests through single files
  • Single and multiple test result management and printout: Data export to MS Excel®
  • Language selection: English, French, Spanish and Italian plus any other custom language
  • Connection to Controls machine with high speed Ethernet connection.

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.
