• Abstract:
  This work involved making a portable X-Ray Fluorescence Spectroscopy device available to district personnel and training them to use the device on a routine basis to analyze tire rubber-modified asphalt binder for tire rubber content. The Performing Agency worked with the Receiving Agency and producers from around the state to develop calibration standards that can be used to determine the tire rubber content using the portable XRF units and conducted a round-robin analysis of samples from across different laboratories. The Performing Agency also revised test procedure Tex 553-C, “Determination of Re-Refined Engine Oil Bottoms, Polyphosphoric Acid, and Tire Rubber Content in Asphalt using X-Ray Fluorescence Spectroscopy” to account for procedures to use in the field since the device is portable.
