HIGHLIGHTS
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
