The   Hamburg   (Dry   &   Wet)   Wheel   Tracker   WTIM-A   is   a   precision dual-arm   system   designed   to   assess   asphalt   mixtures   for   rutting resistance   and   moisture   susceptibility   under   both   wet   and   dry conditions.   Fully   compliant   with   AASHTO-T324   and   EN   12697-22 standards,   it   is   future-proof,   energy   efficient,   and   ideal   for   both quality control and advanced research applications. The   system   provides   automatic,   continuous   rut   depth   measurement at   230   points   across   each   sample,   allowing   detailed   surface   analysis and    roughness    evaluation.    Its    advanced    scotch    yoke    mechanism ensures    perfect    sinusoidal    wheel    motion    with    an    industry-leading RMSE   of   0.039mm,   independently   verified   in   NCHRP   testing.   Flexible test    profiles    allow    automatic    testing    of    one    or    two    specimens, adapting easily to varied laboratory needs. Wheel   load   can   be   adjusted   from   520N   to   1600N   in   1N   increments, with   wheel   speed   variable   from   10   to   36   cycles   per   minute.   Three temperature   probes   ensure   uniform   chamber   conditions,   maintaining a   control   accuracy   of   +/-0.1°C.   Automated   water   filling   and   levelling systems     comply     with     EN     and     AASHTO     requirements,     while     a redesigned   dry   hood   allows   effortless   switching   between   wet   and   dry tests. A   universal   mould   clamping   system   accommodates   multiple   sample sizes—305x305mm,   260x320mm,   305x400mm   slabs,   and   cores   up   to 200mm    diameter—without    additional    parts.    Operator    comfort    and safety     are     enhanced     through     independently     lifting     arms,     three integrated     emergency     stops,     and     quick-release     panels     for     easy maintenance. Combining   precision   engineering,   flexibility,   and   safety,   the   WTIM-A delivers   unmatched   performance   for   Superpave   testing,   balanced   mix design,   rutting   resistance,   and   environmental   research,   setting   a   new standard in asphalt performance evaluation. MAIN APPLICATIONS • Superpave Testing • Balanced Mix Design • Quality Control RESEARCH APPLICATIONS • Resistance to rutting • Moisture susceptibility • Recycled material studies • Environmental studies • Resistance to abrasion • Scuffing • Pothole evaluation • Road markings evaluation SOFTWARE PACKAGE • Both preconfigured and fully flexible test profile configurations • Multiple    test    routines,    which    include    AASHTO,    EN,    BS,    AGPT, TxDOT, and CalTrans • Multi-language    capability    in    the    test    software    and    reports. Reports   can   be   configured   to   a   specific   language   and   specific test method • Automatic final rut profile screenshots at the end of the test • The   reporting   tool   can   be   installed   on   any   networked   or   remote PC

TRUE SINUSOIDAL MOTION Our    Scotch    yoke    mechanism    produces    perfect    sinusoidal    motion throughout    the    stroke    in    full    compliance    with    major    international standards.   This   results   in   consistent,   repeatable,   and   reproducible   test results. RESEARCH GRADE Our   data   acquisition   system   precisely   records   rut   depth   in   230   points across   the   sample.   The   load   can   be   set   from   520N   up   to   1600N   in   1N increments.   Variable   test   parameters   and   flexible   analysis   tools   are included    to    suit    any    research    project    and    future    changes    in    the standards. CONTRACTOR GRADE Our   machine   is   a   smart   solution   for   quality   control.   The   focus   during design   was   to   optimise   workflow   and   testing   time.   With   our   automatic test    scheduling    tool    and    preconfigured    standard    test    routines,    the operator will save time planning and executing tests. ENERGY EFFICIENT An   eco-friendly   smart   heating   system   and   highly   accurate   temperature control with three temperature probes help reduce power usage. USER FRIENDLY New   and   easy-to-use   guard   and   extra   emergency   stop   buttons   with easy    access    from    any    side    protect    the    users    to    the    highest    level. Electromechanical   automatic   arms   reduce   heavy   lifting   demands   from the operator.
