Four Point Bend Test for UTM and AsphaltQube

Precision-engineered Four Point Bend jig specifically designed for performing the Four Point Bend test on UTM-30, UTM-130, AsphaltQube and AsphaltQube Pro.

Four Point Bend Jig

• Innovative “floating straight-edge” on specimen transducer displacement measurement eliminates errors
• Optional fixed point strain measurement referring from outer pivots
• Designed to subject an asphalt specimen to four point bending with backlash free rotation and horizontal translation of all load and reaction points
• Sinusoidal or haversine controlled strain or controlled stress loading
• Controlled force, motorized specimen clamping
• Non-linear regression data fitting ensures reliable determination of phase and modulus
• Can be used with existing UTM or AsphaltQube systems
• Cost effective solution for high volume testing
• Specimen laterally positioned by hand using etched lines as visual guide for two specimen sizes, nominally 50 and 63.5 mm in width
• Vertical clamping of the specimen is achieved by servo-motor driven ball screws, which are operated continuously during the test to take up the compliance of the specimen at the clamping surfaces

Extra Large Four Point Bend Jig

• Innovative floating on-specimen transducer eliminates errors caused by frame compliance
• Backlash free rotation and translation on all load and reaction points
• Controlled force and motorized specimen clamping
• Specimen rollers with pneumatic lift and lowering for easy loading of specimen
• Automated self-aligning specimen yokes for easy specimen insertion
• Specimen roller with pneumatic lift and lowering provide the user with easy test set-up across a range of extra-large specimen sizes
• Vertical clamping of the specimen is achieved by servo-motor driven ball screws, which are operated continuously during the test to take up the compliance of the specimen at the clamping surfaces
