About | People | Equipment | Location


The major objective of the pavement engineering research at the Memorial University of Newfoundland is to contribute to the development of sustainable roads and highways in Canada. Professor Dr. Kamal Hossain and his research group, Advanced Road and Transporation Engineering Lab (ARTEL) conduct research in multiple areas of pavement engineering. The research group focuses on the development and use of more sustainable pavement materials and alterative design technologies and science-based pavement and highway management practices.

Indirect Tensile Strength (ITS) testing system

ITS Testing Machine is used to determine the tensile strength of compacted bituminous mixtures. It can also be used in multiple experiments like Quick Undrained Triaxial, Unconfined Compression and CBR testing with proper accessories.


  • High precision load cell, class 1, and class 0.5 calibration
  • 1/50,000 force resolution
  • 0.5~60 mm/min test speed (upgradable option)
  • User-friendly remote for chuck control
  • Overload protection limit sensor
  • Emergency power cut off button
  • Interchangeable tensile insert grip system

Rotational Viscometer

The rotational viscometer is used to measure the viscosity of a fluid. At a constant speed, torque is produced to rotate a spindle submerged in a fluid. Time-dependent fluid analysis has been conducted with the continuous rotation of the spindle. For materials with low, medium, and high viscosity digital models can be used.


  • Using Rotational Viscometer, AASHTO T 316 and ASTM D 4402 can be conducted.
  • Spindle barcode for auto spindle recognition
  • Quick and easy automatic or manual gap setting
  • Quick profiling of viscosity vs. temperature
  • User-friendly LCD touch screen with graphical display
  • 11 memory slots for structured multi-step test programs
  • Auto spindle identity recognition
  • Quick connect coupling for easy spindle attachment
  • Temperature control from -20°C to180°C
  • Maximum Torque: 100 mN·m
  • Torque Resolution: 0.15 μ N·m
  • Speed: 0.01-1,300 rpm

Convection Oven

The convection oven is used for drying, preheating, curing, dehydrating, aging and many other processes.
