Triaxial test – Universal and Automatic Triaxial Cell for UTM and AsphaltQube

Universal and automatic triaxial cell for UTM and AsphaltQube testing systems specifically designed to perform triaxial tests on asphalt mix.

Universal triaxial cell and AsphaltQube Pro triaxial cell

• Incorporated low friction linear (Thompson) ball bushing on loading shaft to keep fiction to a minimum
• Limited acrylic (see through) area for greater safety
• Facilitates 2 LVDTs and mounting brackets for precise direct shaft position measurement
• Fitted with pressure relief valve for greater safety
• Facilitates external axial strain transducer mounting system
• Facilitates up to three “through the wall” radial strain transducers (UTM only)
• Facilitates internal temperature measurement
• Facilitates three internal transducers with Lemo “feed-through” connectors as standard and has provision of up to five electrical “feed-through” connectors
• Provision of anchor points for the bottom platen and triaxial cell, to facilitate direct tension testing
• Geotechnical version available with pore and back pressure ports
• Versatile, user friendly and accurate device for triaxial confinement of the specimen
• Suitable for asphalt, soils and unbound granular materials

Automatic triaxial cell

• Automatic pneumatically operated lift cylinders that raise and lower the cell wall
• Fitted with pressure relief valve for greater safety
• Crystal clear heavy duty acrylic cell wall for maximum visibility of specimen
• Low friction loading shaft
• Capable of operating between -15° to +60° C
• Provision for pressure and temperature transducers
• Provision for up to three (internal) on specimen transducers
• Cell pressure up to 275 kPa
• Versatile, user friendly and accurate device for lateral confinement of the specimen
• Suitable for asphalt, soils and unbound granular materials

Triaxial cell to be used only with AsphaltQube, in compliance with EN 12697-25B and AASHTO T378 / TP79, is also available.
