DIFFERENT JIGS TO BE USED IN THE ABOVE EQUIPMENT

(i) FATIGUE LIFE OF COMPACTED HMA SUBJECTED TO REPEATED FLEXURE BENDING (AASHTO:T 321-07)

Working Principles

1. Fatigue life and energy of 380 mm long x 50 mm thick x 63 mm wide  beam specimens laboratory or field compacted HMA and subjected to repeated flexure bending until failure
2.  Select desired initial strain (250 to 750 microstrain), loading frequency ( 5 to 10 Hz) and the load cycle intervals
3.  Apply 50 load cycles at a constant strain (250 to 750 microstrain) and find stiffness at the 50th load cycle which is used as estimate of the initial stiffness
4. Minimum of 10,000 load cycles ensures specimen does not decrease in stiffness too rapidly
5.  Failure point: Specimen exhibits a 50 % reduction in stiffness relative to initial stiffness

User Instructions
