    Equipment you can include

    Common equipment for service requests

    These are common repair lanes, not a limit. If the item supports asphalt, aggregate, binder, or QC lab work, send it and we will review it.

    NCAT and ignition furnaces

    Controls, heating issues, sensors, switches, cabinets, and common wear items.

    Gyratory compactors

    Mechanical, electrical, and setup issues that affect repeatable compaction.

    Load frames and Marshall equipment

    Repair support for equipment that needs stable force, speed, and readings.

    Ovens, water baths, and hot plates

    Temperature, controller, circulation, and day-to-day reliability problems.

    Balances and moisture equipment

    Issues that can affect weights, moisture checks, and production decisions.

    Not sure where it fits?

    Send the make, model, photos, and symptoms. We will route it to the right repair path.

    What happens next

    How the service request works

    1. 1

      Describe the issue

      Tell us what changed, what failed, and whether production or an audit is affected.

    2. 2

      Add useful context

      Photos, error codes, make, model, serial number, and recent service history all help.

    3. 3

      Choose ship-in or onsite

      We confirm the practical path, expected timing, and any parts needed before work moves forward.

    Repair path support

    Get a clear service path

    GTSSI focuses repair work where we have the training, parts knowledge, and equipment context to help. If a factory or partner route is the better answer, we will say so.

    • Factory-trained where applicable
    • AASHTO-aware procedures
    • Updates from intake to return

    Service options

    Choose ship-in or onsite service

    Ship-in repair

    Often the fastest route for portable instruments, controllers, boards, and parts that can safely travel.

    Onsite repair

    Best for fixed equipment, difficult-to-ship systems, or repairs that need to happen in the lab.

    Rush review

    Tell us when production, acceptance testing, or an audit is at risk so we can triage urgency clearly.
