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.
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.
