Unitracker – Wheel Tracking Apparatus, Matest Production

This test, developed in laboratory, consists in evaluating the deformation (rut) depth of a bituminous mixture subjected to cycles of passes of a loaded rubber wheel under constant and controlled temperature conditions.
To perform the test, a wheel tracking apparatus is used to simulate the effect of traffic and to measure the deformation susceptibility of the bituminous sample.
Matest wheel tracker performs the test as per procedures A and B (6 or 2 tests), clearly specified by the EN Standard.

Technical specifications
– The machine fully satisfies both EN 12697-22 and BS 598:110 Specifications.
– Travel of the table: 230 +/- 5 mm
– Table cycle frequency: adjustable 15 to 40 cycles per minute.
– Hard rubber tyred wheel having outside diameter 200 mm
– Wheel load on the sample: 700N +/-10N (EN
