Customer Success Story: Auckland Lab Optimises Asphalt and Basecourse Coring with Xcalibre T4D

In 2022, an Auckland lab invested in the Xcalibre T4D coring trailer to streamline their asphalt and basecourse testing. Primarily used for asphalt coring—with occasional work on basecourse or cement-treated basecourse—the trailer accommodates core diameters of 100 mm, 150 mm, and occasionally 200 mm.

Real-World Performance:
Ben, who oversees the operation, shared his experience: initially, the diesel engine was difficult to start in cold and warm conditions, but after repositioning the fuel pump, this issue was resolved. The machine is now permanently connected to a ute, operated by a single person, and consistently meets performance expectations.

They primarily use water grinding for asphalt and dry grinding for basecourse, employing a slotted grinding tube with standard vacuum dust suppression. The trailer is equipped with cameras for precise coring position and area monitoring, a 2-speed motor for coring asphalt, concrete overlays, and treated basecourse. Minor adjustments, such as adding an extra light and initial operator training, were easily managed.

Impact and Benefits:

• The machine fully lived up to expectations.

• Cost savings quickly justified the investment.

• No need for lateral feed movement, as positioning is straightforward.

• Operator-friendly design reduces training and service complexity.

Ben notes that while additional units are unlikely, the lab is also considering a Dynatest FFWD in the next financial year to further improve efficiency. They are gradually moving away from hydraulics where possible, aligning with their operational goals.

The Xcalibre D4 coring trailer has proven to be a reliable, cost-effective solution for the lab, enabling efficient and precise coring operations with minimal staff.
