　　Asphalt fatigue testing machineI, Beijing Zhongde Shenke Technology Co., Ltd., introduced IPC from Australia in accordance with the technical requirements of the industry standard JTG E20-2011 issued by the Ministry of Transport.

standard:

AASHTO T321/TP8

EN12697-24 Appendix D

EN12697-26 Appendix B

Appendix D of prEN13108-20

Application:

Used to test the fatigue life of asphalt mixtures under repeated bending loads.

Introduction:

IPC BFA AustraliaAsphalt fatigue testing machineIt mainly consists of a bracket mechanical system, which is equipped with pneumatic lateral positioning and clamping. A digital servo controlled pneumatic actuator is built into its base.

The Australian IPC BFA pneumatic independent four point bending small beam fatigue test device has a small beam support system designed to apply a 4-point bending load to asphalt mixture small beams, and allows all loading and reaction points to freely translate and rotate.

The servo motor driven by ball screw is used for vertical clamping of the specimen. The motor continues to work during the testing process, tightening the slack formed on the clamping surface due to deformation of the specimen. The clamping force is controlled by adjusting the motor current. The power supply for the motor drive circuit is provided by IMACS.

The Australian IPC BFA pneumatic independent four point bending small beam fatigue test device includes a control and data acquisition system as well as test software.

System features:

-Compact design, independent testing system, no need for UTM series loading rack

-Digital servo controlled pneumatic actuator provides precise loading waveform control

-The new 'floating straight edge' sample surface sensor reduces errors (including errors caused by the flexibility of the bracket)

-Sine or semi sine strain/stress control loading modes

-Electric specimen clamping with controllable force

-Pneumatic lateral fixture helps straighten the position of the small beam
