Description

Reference laboratory equipment designed to study the rutting resistance of asphalt mixtures under conditions comparable to those experienced by pavements under traffic, in accordance with standard EN 12697-22.

Two asphalt specimens are simultaneously subjected to repeated passes of a wheel fitted with a pneumatic tire, under a specified load and controlled temperature. The wheel can be fitted with an angle to introduce a lateral slip effect.

Automation reduces the test duration by a factor of three and saves 50% of the operator’s time.

The equipment therefore pays for itself quickly compared with a conventional wheel tracker.

The mlpc® Wheel Tracker has been sold in many units worldwide and is an essential tool for asphalt mix design. The latest generation goes even further: higher temperature capability, full enclosure, and redesigned control and ergonomics to meet the needs of today’s laboratories.

Highlights

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

User comfort

→ Easy use thanks to sliding doors, reduced operating noise, large touch screen, numerous connections
→ Optimal visibility of the test
→ Optimized interface: large touch screen, numerous connectivities
→ Reduced operating noise
→ Supervision by light column

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

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

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.).

Monitoring test parameters

→ 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
