B049-30, FATIGUE TESTING OF ASPHALT BEAMS APP

Λεπτομέρειες
Κατηγορία: Ασφαλτικά / Bitumen - Asphalt

Standard: SHRP M009
      Description: The Beam Fatigue Apparatus is a stand-alone system for fatigue life testing of asphalt beams subjected to repeated flexural bending, giving a measure of maximum tensile strength,maximum tensile strain and flexural stiffness.The cradle mechanism allows for free translation and rotation of the clamps and provides loading at the third points.
Pneumatic actuators at the ends of the beam centre it laterally and clamp it.Servo-motor driven clamps secure the beam at the four points with a predetermined clamping force. Software has been developed to automatically perform the SHRP M009 test.
The latest software allows for both controlled strain and stress loading.
