• Abstract:
  This work involved providing support to the Lufkin, Odessa, and Brownwood Districts during their 2024 seal coat season for determining the tire rubber content using portable XRF units. CTR staff travelled to the three districts to conduct training refreshers and assist in analyzing field samples used in district seal coats. Analysis was performed on the roadside, demonstrating the ability to conduct analysis in the field. Additionally, staff conducted a round-robin analysis of samples from across the three districts using AR binder, which also served to develop a calibration for a specific combination of base binder and tire rubber.
