To perform Four Point Bend test

Main features

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

Loading frequency up to 60 Hz

Non-linear regression data fitting ensures reliable determination of phase and modulus

Can be used with existing UTM 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
