Can X- Ray Fluorescence Analysis be Used to Identify Asphalt Binders? Federal Highway Administration Turner-Fairbank Highway Research Center (TFHRC) McLean, VA Terry Arnold, FHWA Susan Needham, SES Group & Associates Anant Shastry, ESC & Associates Petersen Asphalt Conference and P3 Symposium 2010 Is this Binder What We Think It Is? Can XRF help? X-Ray Fluorescence is a simple technique for the quantitative analysis of elements, typically from Sodium to Uranium in the Periodic Table. X-Ray Fluorescence is a simple technique for the quantitative analysis of elements, typically from Sodium to Uranium in the Periodic Table. XRF Spectroscopy Can Detect: Polyphosphoric Acid (PPA) Recycled Engine Oil Bottoms (REOB) Crumb Rubber Modified (CRM) Among Other Things XRF Analysis of PPA Modified Asphalt % PPA Content Actual Found Sample Number Lubricating Oil Additives Contain: Zinc, Phosphorous, Calcium Detection of Recycled Engine Oil Bottoms in Asphalt Binders l Content ppm Metal Phosphorous Calcium Iron Zinc Molybdenum Tin Waste Oil Residue % Crumb Rubber Modified Asphalt The main activator used to assist in the Vulcanization of Rubber is Zinc (Zn) Crumb Rubber also contains: Calcium (Ca) Iron (Fe) Copper (Cu) Lead (Pb) Potassium (K) Titanium (Sn) Bromine (Br) Crumb Rubber ppm 4000 ppm Potassium Calcium Titanium Iron Copper Zinc Bromine Lead Terminal Blend Crumb Rubber Asphalt Pre Modification After Modification with CRM 945 ppm 250 ppm Potassium Calcium Titanium Iron Copper Zinc Bromine Lead Arizona Crumb Rubber Asphalt Pre Modification After Modification with CRM 6330 ppm ppm Potassium Calcium Titanium Iron Cobalt Copper Zinc Bromine Lead Can XRF help with Forensic Analysis?
