Slurry Testing Machine

Clear

High quality, simple and reliable machine, complies to EN 12774-5 for the determination of wearing and minimum binder content

The slurry surfacing test machine CRT-STM also known as Wet Track Abrasion Test Machine was developed to simply and reliably determine the minimum binder content of the mix under wet track abrasion conditions according to the determination of wearing test: EN 12274-5.

Standards

  • EN 12274-5
  • ASTM D3910
  • ISSA TB100

Key Features


  • Abrasive head according to EN 12274-5
  • Planetary gear system providing the abrasive head with rotating speed of 144rpm for 61 complete cycles of the planetary system
  • Test bath fitted with three spindles to fix the test base plate
  • 310mm diameter and 5mm thick test base plate with 3 or 4 knurled head screw fasteners
  • Hose can be supplied made from 80° shore hardness rubber. The rubber is reinforced with double cord surface
  • The hose has an internal diameter 19mm and an external diameter of 31mm
  • Integral timing device stops the test automatically after 300 seconds
  • Type A,B,C and D Ring shaped annular metal moulds available


Key Uses

  • Determination of wearing
