Wheel Tracker Large Device with automatic measurement
NF EN 12 697-22 (Large Device)
PAVEMENT RUTTING TESTER: Orniéreur Test methods for determining the susceptibility of bituminous materials to deform under load. Level 2 of the French Mix Design procedure.
Laboratory equipment designed to study the rutting of asphalt mixes under conditions comparable to the stresses on pavements under traffic, according to standard EN 12697-22.
Two asphalt specimens are simultaneously subjected to repeated passages of a wheel equipped with a tire, under a certain load and under controlled temperature. It is possible to integrate or not to the wheel an angle allowing to introduce a lateral skidding effect.
Automation cuts the testing time by a factor of three and saves 50% of the laboratory worker’s time. The equipment therefore quickly pays for itself compared to a traditional rutting machine.
Many copies of Orniéreur mlpc® have been distributed throughout the world, it is an essential tool for the formulation of asphalt mixes. The latest generation allows you to go further: higher temperature rise, new cowling, control and ergonomics redesigned for the needs of today’s laboratories.
Full automatic testing → At each measurement step, without human intervention and in compliance with the standard; → Uninterrupted sequence of the different steps with improved repeatability of the measurement points positioning.
Optimized operator time → With automatic measurement, no more need to monitor and intervene at each measurement level. Focus on the essentials ! → Can be paused at any time.
User comfort → Easy use thanks to sliding doors, reduced operating noise, large touch screen, numerous connections. → Optimal visibility of the test.
Configurable → Developed to carry out the normative test. → Possibility of research-type tests thanks to the many parameters included (temperature up to 80 °C, number of measurement levels, position of the measurement points, modification of the thresholds, etc.).
Energy efficiency → A cowling with its reinforced insulation, which limits the heating cycles for the rise of temperature, but also to maintain it throughout the test. → The opening of the doors during the test is avoided thanks to the automatic measurement.
Durability → Units with service lives in excess of 20 years in heavy conditions.
Ease of maintenance → Thanks to the cowling, which can be partially or completely dismantled.
