Description

Reference 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.
The tire load is focused to the maximum, since the wheel always passes through the same place. It is possible to integrate or not to the wheel an angle allowing to introduce a lateral skidding effect.
Many units of Orniéreur mlpc® have been widely distributed throughout the world, it is an essential tool for the asphalt mix design. The latest generation allows you to go further: higher temperature rise, new body, control and ergonomics redesigned for the needs of today’s laboratories.

 

Automatic measurement
→ At each level, without human intervention and in accordance with the standard.
→ The chain of the different measurement steps without waiting, with greater repeatability of the measurement point 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
→ Optimized interface: large touch screen, numerous connectivities.
→ Ergonomic access: sliding doors, high access, simplified sample transfer.
→ Reduced operating noise.
→ Optimal visibility while testing.
→ Three-color-light system follow-up.

 

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 body 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.

 

Monitoring of test parameters
→ The system monitors the elements that can impact the results (pressure, temperatures, punctures, test of the measurement system, possible faults, etc.) throughout the duration of the test.

 

Durability
→ Units of this traffic simulator that exceed life cycles of over 20 years life spans.

 

Ease of maintenance
→ Thanks to the bodying with removable panels, which can be partially or completely dismantled.
