The Troxler Disk-shaped Compact Tension and Texas Overlay Test Machine (DCT - OT) offers the following features.

  • Test results are printed and plotted immediately. There is no prost processing.
  • The DCT is completely contained on a rolling portable test frame that is designed to carry the load through the conventional pins used by DCT to load the specimen. 
  • It comes with a Texas Overlay test fixture and a copper tub.
  • The system is designed to meet the most current AASHTO D7313 standard.
  • A built-in insulated chamber in a chest style configuration with a flip top eliminates immediate air exchange when opening the chamber to change a specimen.
  • The system includes a 4500 lb force actuator with low friction seals and a magneto restrictive position sensor that is controlled by a proportional valve for closing the loop to control load, position, or strain.
