• Abstract:
  The objectives identified when applying for implementation assistance were as follows: Determine which material properties can be accurately identified using portable XRF. Materials to be included in the proof-of-concept are: Traffic paint – measure Titanium content and check for dilution. Asphalt binder – check for presence of wear metals and lubricants (zinc, copper, molybdenum) which are indicative of recycled lubricating fluids. Portland cement – rapid field chemical analysis. Glass beads – measure arsenic and lead content for EPA compliance. Reinforcing steel – alloy content for corrosion-resistant bars Guardrail & fasteners – measure thickness of galvanized coating Recycled Asphalt Shingles (RAS) – measure copper content for potential use as a means to identify presence of RAS in asphalt mixture. Bridge deck core specimens – measure chloride content Investigate use of FTIR for testing the following material properties: Hydrated lime content of asphalt mixture. Polymer content of asphalt binder.
