Three-Wheel Asphalt Rutting Tester | Hamburg Wheel Tracking Device | EN 12697-22 AASHTO T324 Compliant | High Temperature Stability Test Machine for Bitumen Mixture

The Three-Wheel Rut Tester (Triple Wheel Tracking Device) is essential equipment for evaluating high-temperature rut resistance and moisture susceptibility of asphalt mixtures, widely used in highway research institutes, quality control centers, and asphalt production facilities for mix design and quality assurance.

Key Functions:

• Three-Wheel Independent Drive: Two test wheels driven by separate servo motors, individually controlled; when one specimen reaches target rut depth, it stops automatically while the other continues unaffected

• Multi-Mode Testing: Supports dry (air heating), wet (water bath), immersed, and high-temperature test modes to evaluate rutting characteristics under various environmental conditions

• High-Precision Measurement: Equipped with LVDT or laser displacement sensors, 0.01mm resolution, ±0.05mm accuracy, real-time monitoring of rut depth development

• Intelligent Temperature Control: PID regulation technology, water bath or air bath temperature range ambient to 80°C, ±0.5°C precision, ensuring stable test temperature

• Automatic Protection: Automatic wheel lifting device prevents pre-loading damage; rubber wheel wear marks for roundness inspection; automatic alarms for overtemperature and overload

• Powerful Software: Windows OS, automatic calculation of dynamic stability, creep slope, and strip inflection point, generating test reports compliant with AASHTO and EN standards

• Three-Point Data Acquisition: 5 predetermined measurement points along specimen length, 3 readings per point, 15 rut data points automatically captured for representative results
