DWT Universal Double Wheel Tracker Kuwait

DWT Universal Double Wheel Tracker Kuwait is Burgan Equipment Co.'s wheel tracking system for measuring the rutting resistance and moisture susceptibility of hot mix asphalt. Built by Controls Group, it is supplied with both stainless steel and rubber wheels and tests in air or water, so a single machine covers both AASHTO T324 Hamburg testing and EN 12697-22. Two loaded wheels run back and forth over two specimens at once while built-in transducers record rut depth throughout the test. Burgan supplies, installs and supports the DWT Universal for highway, research and quality control laboratories across Kuwait.

Key system highlights

DWT Universal Double Wheel Tracker Kuwait: one machine for both AASHTO and EN wheel tracking tests.
Rutting and moisture damage: measures permanent deformation and stripping, key risks for asphalt roads in Kuwait’s heat.
Two wheel types included: stainless steel wheels for AASHTO T324, rubber tyres for EN 12697-22.
Air or water testing: built-in temperature-controlled cabinet for both conditions.
Two specimens at once: fully automatic testing on one or two samples.
Accurate temperature control: ambient to 80 °C, ±0.5 °C in both air and water.
Precise rut measurement: transducers with 50 mm travel and 0.01 mm accuracy, aligned with each wheel’s centre.
Standard-compliant motion: sinusoidal wheel movement and rut depth measured at 11 defined points to AASHTO T324-19.
Variable speed: 20 to 30 cycles per minute over 230 mm wheel travel.
Automatic water filling and levelling: no manual checking of water level during the test.
Motorized wheel lifting: raises the wheel assembly at the end of the test for easy slab removal.
Flexible samples: slabs, 150 mm gyratory cylinders, and 200 mm, 8″ or 10″ cores.
Programmable start: preheating and test start can run without an operator present.
Stainless steel construction: used throughout the machine, not only on wetted parts.
PC and software included: test control, results database and multi-test analysis.
