Standars AASHTO T307, TP46
Designed and manufactured to high precision and quality, the Universal Triaxial Cell provides a versatile, user friendly and accurate device for testing applications where lateral confinement of the specimen is necessary. This triaxial cell is suitable for a range of materials including asphalt, soils and unbound granular materials.
To comply with AASHTO T307 and AASHTO TP46 the cell incorporates low friction linear (Thompson) ball bushing for the loading shaft to keep fiction to a minimum and facilitates two LVDTs and mountings brackets for precise direct shaft position measurement.

SPECIFICATIONS
Features
• Low friction linear (Thompson) ball bushing on loading shaft (AASHTO/T307).
• Limited acrylic (see through) area for greater safety.
• Fitted with pressure relief valve for greater safety.
• Facilitates external axial strain transducer mounting system (as recommended in AASHTO TP46/T307).
• Facilitates up to three “through the wall” radial strain transducers.
• Facilitates internal temperature measurement.
• Provision of up to five electrical “feed through” connectors (three provided as standard) to accommodate internal transducers.
• Provision of anchor points for the bottom platen and triaxial cell, to facilitate direct tension testing.

How it works
The cell’s innovative modular design allows you to perform tests on a variety of specimen sizes (up to 300mm high) whilst still maintaining good visibility of the specimen during the test and keeping the three through-the-wall ports for on specimen radial strain transducers positioned at the centre of the specimen.
Use water or air for confinement to achieve pressures up to 700kPa or 400kPa respectively. The cell also incorporates provision for internal temperature measurement and up to 5 electrical connections (3 Swiss made connectors fitted as standard) for on-specimen transducers.
A range of top and bottom platens is available to accommodate various specimen sizes (metric and US customary units). By combining the Universal Triaxial Cell with an Universal Testing Machine, IMACS digital controller and UTS software gives you a flexible, powerful and user friendly system that meets international test standards.
