Rapid Angle Measurement Device for Superpave Gyratory Compactor

Rapid Angle Measurement Device for Superpave Gyratory Compactor

The Rapid Angle Measurement Device (RAM) is a state-of-the-art instrument designed to quickly and accurately verify and calibrate both internal and external angles on any Superpave Gyratory Compactor using 150mm molds. Engineered for efficiency and safety, the RAM Device streamlines the calibration process, taking only a few minutes to complete the measurements required by AASHTO T312, without the need to handle hot molds or asphalt mix.

The device is entirely self-contained, featuring intuitive push-button controls and a clear LED display, eliminating the need for a computer interface. Simply operate the compactor with the RAM Device inside the mold, remove it, and read the result directly on the display. This straightforward process ensures accurate measurements at room temperature, reducing risk and improving workflow in your lab.

Each RAM Device comes with a NIST traceable certified calibration tube, ensuring the highest level of measurement accuracy and reliability. The certification is valid for one year, giving you peace of mind that your measurements meet the most stringent industry standards.
